# Every query takes something for granted. Presupposition is the name for what it assumes. Canonical: https://www.searchresultoptimization.com/seo/presupposition/ Author: Johannes Faupel Last revised: 2026-09-16 A query asks one thing and assumes several others. The assumptions decide which answer can help. Presupposition is the part of meaning that a sentence takes for granted. Linguistics has studied it for more than a century. This page states what is settled, what the usual treatment leaves out, and what follows for a page that wants to answer the assumption behind a query as well as the query. Every heading is a question. The answer stands directly under it, in plain words. ## What is a presupposition? A presupposition is a background assumption that an utterance takes to be true without stating it. When did you stop smoking presupposes that you smoked. A query carries presuppositions in the same way, and they are part of the user intent. *How to act on presuppositions with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Write down what your query takes for granted, then search once without it | A notes app, Google search | Options your assumption excluded | | SEO | List what the page's main queries assume and check whether the page names it | Search Console queries tab and Google Sheets | Assumptions the page accepts silently | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:"why does" OR intitle:"how to stop"` | Titles that carry an assumption | *Who benefits from presuppositions, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Names what a query takes for granted | Visibility for people whose need lies beyond the assumption | | SEO | Lists assumptions behind main queries | Content that serves the need, beyond the premise | | Readers | See options their assumption excluded | Better choices | ## What is a presupposition trigger? A presupposition trigger is a word or construction that introduces an assumption, such as stop, again, the, regret or also. The trigger is visible in the words. The assumption it brings is not. *How to act on presupposition triggers with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Look for words like stop, again, still or best in your query | A notes app | The assumption each word brings | | SEO | Filter the page's queries for trigger words | Search Console, custom regex filter for stop, again, still, best | Queries that carry a built-in assumption | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:again OR intitle:still OR intitle:stop` | Titles with trigger words | *Who benefits from presupposition triggers, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | SEO | Filters queries for trigger words | A map of assumptions in search demand | | Content team | Chooses title words that assume only what is true | Titles that do not mislead | | Readers | Notice what their words assume | Clearer questions | Also discussed at [https://plato.stanford.edu/entries/presupposition/](https://plato.stanford.edu/entries/presupposition/#:~:text=forming%20a%20large%20class%20including%20definites%20and%20factive%20verbs) ## How does negation reveal a presupposition? A presupposition survives negation. I did not stop smoking still assumes that I smoked. This test separates a presupposition from what a sentence merely implies. *How to act on the negation test with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Negate your question and see what stays assumed | A notes app | The part you take for granted | | SEO | Apply the negation test to the page's title and check what it still assumes | The page title and a colleague's reading | Assumptions the title makes for every reader | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:"why not" OR intitle:"doesn't"` | Negated titles that may still assume something | *Who benefits from the negation test, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Tests titles for what they still assume | Titles that fit every reader | | Legal and compliance | Finds claims that assume more than stated | Fewer implied promises | | Readers | Get content without hidden assumptions | Trust | Also discussed at [https://plato.stanford.edu/entries/presupposition/](https://plato.stanford.edu/entries/presupposition/#:~:text=Projection%20from%20embeddings%2C%20especially%20negation%2C%20is%20standardly%20used%20as%20a%20diagnostic%20for%20presupposition) ## What is common ground between a searcher and a search system? Common ground is the body of knowledge and beliefs that people in a conversation take as shared. Presuppositions are drawn from it. Between a searcher and a search system, the common ground is thinner than the searcher assumes. *How to act on common ground with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Add context the search box cannot know: your situation, place, prior attempts | Google search | Results that do not rely on missing common ground | | SEO | State on the page the background it assumes readers share | The page itself | Readers who know whether the page applies to them | | Your site | Check your own domain; replace example.com with it | `site:example.com "as you know" OR "of course"` | Pages that assume shared knowledge | *Who benefits from common ground, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | States the background a page assumes | Visitors who know whether it applies | | Customer support | Gets fewer questions caused by missing context | Shorter contacts | | Readers | Know whether a page fits their situation | Less misapplied advice | ## What is presupposition accommodation by a search system? Presupposition accommodation is the process by which a listener silently accepts an assumption that was not yet part of the common ground. David Lewis described it in 1979. Search systems accommodate every assumption in a query, true or false. *How to act on presupposition accommodation with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Treat results that accept your assumption as unproven | A second search that questions the assumption | Whether the assumption holds | | SEO | Find queries whose assumption the page accepts without checking it | Search Console queries tab, People also ask | Where the page accommodates a false assumption | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:"why" "cure" OR "proven"` | Pages that may confirm an assumption | *Who benefits from presupposition accommodation, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Checks assumptions before answering them | Pages trusted for correcting premises | | Legal and compliance | Avoids confirming false claims | Lower risk | | Readers | Are not confirmed in a false belief | Protection from errors | If a model handled a false assumption as well as an ordinary question, both columns would match. For every model the right column is lower. *Acceptable answers to real search queries, with and without a questionable assumption* | Model (no examples given) | Query with sound assumptions | Query with a questionable assumption | | --- | --- | --- | | GPT-3.5 (text-davinci-003) | 56 % | 40 % | | Flan-PaLM 540B | 48 % | 8 % | | PaLM 540B | 28 % | 14 % | | REALM | 26 % | 10 % | | Flan-T5-XXL | 22 % | 10 % | Kim, N., Htut, P.

Human-judged acceptability on 100 questions built from frequent search engine queries, zero-shot setting. ## What is a definite description in a query? A definite description is a noun phrase with a definite article, such as the best treatment. It presupposes that such a thing exists and is unique. Bertrand Russell and Peter Strawson disagreed about it for decades. *How to act on definite descriptions with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Search the best treatment as a treatment, then compare | Google search | Options beyond the one assumed best | | SEO | Check queries with the best or the only and state whether a single best exists | Search Console queries containing the best | Uniqueness the query assumes | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:"the best"` | Titles that assume one best option | *Who benefits from definite descriptions, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Says whether a single best option exists | Visibility for the best queries with an honest answer | | Sales | Compares options openly | Trust from buyers | | Readers | See the real range of options | Better decisions | Also discussed at [https://plato.stanford.edu/entries/presupposition/](https://plato.stanford.edu/entries/presupposition/#:~:text=which%20are%20said%20to%20presuppose%20the%20existence%20of%20a%20unique%20referent) ## How does entailment differ from presupposition? Entailment is a relation in which the truth of one sentence guarantees the truth of another. When the sentence is negated, an entailment falls away and a presupposition stays. The difference shows what a query really takes for granted. *How to act on entailment and presupposition with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Ask which part of an answer must be true if the claim is true, and which part is assumed | A notes app | What is claimed and what is assumed | | SEO | Separate stated claims from assumed background in key passages | The page itself | Claims readers can check separately | | Your site | Check your own domain; replace example.com with it | `site:example.com "this means that"` | Passages that state consequences | *Who benefits from entailment and presupposition, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Separates stated claims from assumed background | Passages that can be quoted precisely | | Legal and compliance | Keeps claims checkable | Defensible statements | | Readers | Check claims separately from their background | Clear understanding | ## How does implicature differ from presupposition? Implicature is meaning a listener infers from context, as Paul Grice described it. It can be cancelled easily, while a presupposition is built into the words. Both carry more than the query says. *How to act on implicature and presupposition with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Check whether a suggestion in a result is stated or only implied | The page itself | Claims the page does not actually make | | SEO | Remove implications in titles that the page cannot back | Search Console titles and the page | Titles that imply more than the page delivers | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:"secret" OR intitle:"trick"` | Titles that imply more than they say | *Who benefits from implicature and presupposition, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | SEO | Removes implied promises from titles | Clicks that turn into satisfied visits | | Legal and compliance | Avoids implications the page cannot back | Fewer complaints | | Readers | Get what titles imply | No disappointment | ## What is a false presupposition? A false presupposition is an assumption in an utterance or a query that is not true. Why does vitamin C cure colds presupposes that it does. Answering such a question as asked confirms the error. *How to act on false presuppositions with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Search the assumption itself with the words fact check or evidence | Google search, Google Fact Check Explorer | Whether the premise of your question is true | | SEO | Find queries built on a false assumption and answer the assumption first | Search Console queries tab, Google Fact Check Explorer | Visitors who get the premise corrected | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:myth OR intitle:"is it true"` | Pages that correct false premises | *Who benefits from false presuppositions, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Corrects the premise before answering | Pages cited as corrections | | Customer support | Links pages that correct common false beliefs | Fewer repeated misunderstandings | | Readers | Learn that the premise was wrong | Better decisions | Also discussed at [https://arxiv.org/abs/2212.10003](https://arxiv.org/abs/2212.10003#:~:text=Questions%20containing%20questionable%20assumptions%20are%20challenging%20because%20they%20require%20a%20distinct%20answer%20strategy) 26 % of these questions rest on a false presupposition. If spotting it were easy, the model and the searching person would score close to the person holding the best reply. *Spotting false presuppositions in questions people asked on Reddit* | Who judges the question | Detection score (macro-F1, test set) | | --- | --- | | Baseline that always says "no false presupposition" | 42.9 | | Best model, reading Wikipedia passages | 67.1 | | Person searching the web | 70.9 | | Person reading the most upvoted reply | 85.1 | Yu, X. V., Min, S., Zettlemoyer, L. and Hajishirzi, H., CREPE: Open-domain question answering with false presuppositions, ACL 2023. 8,466 labeled questions from r/explainlikeimfive, human scores on 186 questions. ## What are holes that let assumptions pass through a sentence? Holes, in Lauri Karttunen's terms, are expressions that let the presuppositions of an embedded sentence pass up to the whole sentence, such as know or be surprised. The assumption travels outward. The speaker is still committed to it. *How to act on presupposition holes with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Notice verbs like know or be surprised that carry an assumption into your query | A notes app | Assumptions hidden in reported facts | | SEO | Check headlines with know, realise or discover for assumptions they pass on | The page's headings | Headlines that commit the page to a claim | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:"did you know"` | Titles that pass an assumption to the reader | *Who benefits from presupposition holes, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Checks headlines for assumptions they pass on | Headlines the page can stand behind | | Legal and compliance | Avoids headlines that commit to unverified facts | Lower risk | | Readers | Get headlines that assume only what is true | Trust | ## What are plugs that block assumptions in reported speech? Plugs are expressions that block presuppositions of an embedded sentence, such as say or tell. The assumption stays inside the reported speech. The speaker is no longer committed to it. *How to act on presupposition plugs with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Separate what a source says from what the page itself claims | The page itself | Who is committed to the claim | | SEO | Mark reported claims with says or claims so the page is not committed to them | The page itself | Claims correctly attributed | | Your site | Check your own domain; replace example.com with it | `site:example.com "claims that" OR "says that"` | Pages that report claims | *Who benefits from presupposition plugs, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Attributes reported claims clearly | Passages quoted correctly | | Legal and compliance | Keeps the site uncommitted to reported claims | Lower liability | | Readers | Know who claims what | Correct understanding | Also discussed at [https://plato.stanford.edu/entries/presupposition/](https://plato.stanford.edu/entries/presupposition/#:~:text=Plugs%20comprise%20a%20class%20of%20predicates%20and%20operators%20which%20Karttunen%20claimed%20block%20the%20projection%20of%20presuppositions) ## What are filters that let assumptions pass under conditions? Filters are constructions such as if and or that let a presupposition pass under some conditions and block it under others. If John has children, his children are asleep does not assume that John has children. Context decides. *How to act on presupposition filters with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Rephrase your query with if to test a condition | Google search | Results that treat the condition | | SEO | Answer conditional queries with the condition stated | Search Console queries containing if | Answers that keep the condition | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:"what if" OR intitle:"if you"` | Pages for conditional questions | *Who benefits from presupposition filters, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Keeps conditions in answers | Visibility for if queries | | Customer support | Gives conditional answers | Fewer wrong applications | | Readers | Get answers that respect their condition | Correct advice | ## What is an anaphoric presupposition trigger? An anaphoric presupposition trigger, such as again or too, needs something in the prior context to refer to. It cannot simply be accommodated. In a single query without context, it points to something the system never saw. *How to act on anaphoric triggers with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Replace again or too with what you mean in a new search | Google search | Results for the thing you referred to | | SEO | Find queries with again or too that point to a prior event and address it | Search Console custom regex filter for again, too | Needs that depend on earlier experience | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:again` | Pages for recurring problems | *Who benefits from anaphoric triggers, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Addresses recurring problems explicitly | Visibility for again and still queries | | Customer support | Recognises repeat problems | Better help for returning customers | | Readers | Get help that knows it happened before | Solutions that last | Described in a Google patent: [https://patents.google.com/patent/US9547690B2/en](https://patents.google.com/patent/US9547690B2/en#:~:text=terms%20that%20indicate%20contextual%20intent%2C%20e.g.%2C%20use%20of%20pronoun%20or%20other%20referential%20term%20in%20the%20query) ## What happens to a truth value when a presupposition fails? When a presupposition fails, the sentence can lack a truth value, as Peter Strawson argued. The king of France is bald is neither clearly true nor clearly false while there is no king of France. A query built on a failed assumption has no correct answer in its own terms. *How to act on failed presuppositions with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | When no answer seems to fit, check whether the question itself is flawed | A second search on the premise | A question worth asking | | SEO | Say plainly on the page when a question has no answer as asked | The page itself | Honest answers to flawed questions | | Your site | Check your own domain; replace example.com with it | `site:example.com "there is no" OR "does not exist"` | Pages that address non-existent premises | *Who benefits from failed presuppositions, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Says when a question has no answer as asked | Pages trusted for honesty | | Management | Chooses honest answers over engagement tricks | Credibility | | Readers | Learn to ask a better question | Time saved | Also discussed at [https://plato.stanford.edu/entries/presupposition/](https://plato.stanford.edu/entries/presupposition/#:~:text=that%20the%20question%20whether%20the%20statement%20is%20true%20or%20false) ## How does presupposition relate to user intent? User intent is the goal and motivation behind a query. Presuppositions are the part of that intent the person no longer questions. They mark where the search intent read from the words and the user intent begin to part. *How to act on presupposition and user intent with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Name the goal behind your query and the assumption you made on the way | A notes app | Where your intent and your words part | | SEO | Ask visitors what they want and what they assumed | Google Forms with two open questions | Assumptions inside the user intent | | Your site | Check your own domain; replace example.com with it | `site:example.com "what you really need"` | Pages that look past the assumption | *Who benefits from presupposition and user intent, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Serves the goal beyond the assumption | Visitors whose real need is met | | Management | Sees demand hidden behind assumptions | New audiences | | Readers | Get help for what they really want | Better outcomes | ## What does the usual treatment of presupposition leave out? What happens when the assumption is wrong. The usual treatment names triggers and accommodation. It leaves out how assumptions project through longer queries, what happens when they fail, how they can be cancelled, and how a system could ask back. For search, that missing part is the whole problem: the headache tablet already assumed a pill. *How to act on what the usual treatment of presupposition leaves out with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | SEO | Track queries where the assumption is wrong and measure what the page does with them | Search Console and Google Sheets | Failed assumptions the page ignores | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:"do you really need"` | Pages that question an assumption | *Who benefits from what the usual treatment of presupposition leaves out, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | SEO | Tracks queries with wrong assumptions | Pages that catch failed assumptions | | Management | Invests in correcting assumptions | Trust and new demand | | Readers | Are not left with a wrong premise | Protection | ## What is the projection problem in longer queries? The projection problem asks when the presuppositions of a part of a sentence become presuppositions of the whole. Karttunen's holes, plugs and filters are one answer. A query with a conjunction or a condition can keep an assumption or drop it, and a system has to know which. *How to act on the projection problem with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Split a long query and see which part carries the assumption | Google search | The assumption that survives | | SEO | Read long queries of the page and mark whether the assumption holds for the whole | Search Console queries tab sorted by length | Assumptions kept or dropped in long queries | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:"your topic" inurl:faq` | Question pages where long, combined queries land | *Who benefits from the projection problem, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | SEO | Reads long queries for kept or dropped assumptions | Answers that fit complex queries | | Content team | Answers combined questions carefully | Visibility for long queries | | Readers | Get answers that follow their full query | Accuracy | Also discussed at [https://plato.stanford.edu/entries/presupposition/](https://plato.stanford.edu/entries/presupposition/#:~:text=that%20the%20full%20complexity%20of%20the%20projection%20problem%20became%20apparent) ## What is presupposition failure? Presupposition failure occurs when an assumption of an utterance is not met. The communication breaks down, whatever answer follows. A system that treats a failed assumption as an ordinary query answers a question that should not be answered as asked. *How to act on presupposition failure with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Stop and reframe when results answer a question you did not really have | A notes app | A better question | | SEO | Add a short passage that corrects the assumption before answering | The page itself | Visitors whose failed assumption is caught | | Your site | Check your own domain; replace example.com with it | `site:example.com "actually" OR "contrary to"` | Pages that correct assumptions | *Who benefits from presupposition failure, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Corrects the assumption before the answer | Visitors whose question is reframed | | Customer support | Gets fewer problems from wrong assumptions | Less rework | | Readers | Ask the right question | Better results | If unanswerable queries failed mainly because the search went wrong, the first row would be small. It is the largest cause by far. *Why questions from Google search had no answer* | Cause of the missing answer | Share of questions | | --- | --- | | The question presupposes something that cannot be verified | 30 % | | Unresolved reference, such as "I" | 9 % | | The answer was in the document after all | 8 % | | The wrong page was returned | 6 % | | The question asks for a subjective judgment | 3 % | Kim, N., Pavlick, E., Karagol Ayan, B. and Ramachandran, D., Which linguist invented the lightbulb?

A factive verb, such as realise, regret or know, presupposes that its complement is true. Paul and Carol Kiparsky described the class in 1970. A query like why do people regret buying electric cars assumes the regret is real. *How to act on factive verbs with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Check whether the fact after regret or realise is really true | Google search on the fact | Whether the premise holds | | SEO | Find queries with regret, realise or know and verify their assumed fact | Search Console custom regex filter | Facts the query assumes | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:regret OR intitle:realise` | Titles that assume a fact | *Who benefits from factive verbs, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Verifies the fact a query assumes | Pages that correct or confirm with evidence | | Legal and compliance | Avoids confirming unverified facts | Lower risk | | Readers | Learn whether the assumed fact is true | Sound decisions | ## What is a lexical presupposition trigger? A lexical presupposition trigger is a single word that brings an assumption, such as stop, again or manage. It differs from structural triggers built into sentence form. Separating the two shows where in a query the assumption sits. *How to act on lexical triggers with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Remove a single trigger word and compare results | Google search | Results without the assumption | | SEO | Build a list of trigger words in your field's queries | Search Console export and Google Sheets | Where assumptions enter queries | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:manage OR intitle:stop` | Titles with lexical triggers | *Who benefits from lexical triggers, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | SEO | Lists trigger words in the field's queries | Targeted corrections | | Content team | Uses trigger words deliberately | Titles without unintended assumptions | | Readers | See how single words shape results | Better queries | ## What is an informative presupposition? An informative presupposition introduces new information in the form of an assumption, as in I have to pick up my sister from the airport said to someone who did not know about the sister. The listener learns it without being told. Queries do this constantly, and the new information shapes what the person needs. *How to act on informative presuppositions with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Notice new information your query reveals about you | A notes app | Context worth adding explicitly | | SEO | Read what queries reveal about the person, such as my sister or my landlord, and serve that situation | Search Console queries with my | Situations hidden in queries | | Your site | Check your own domain; replace example.com with it | `site:example.com "my landlord" OR "my employer"` | Pages for situations people reveal | *Who benefits from informative presuppositions, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Serves situations queries reveal | Visibility for situational queries | | Sales | Recognises the situation behind a request | Offers that fit | | Readers | Get help for their situation | Relevant answers | ## What is a cleft sentence in a query? A cleft sentence has the form it was X that Y, and it presupposes that someone or something did Y. It isolates the new part from the assumed part. Queries phrased this way say which part the person already takes as settled. *How to act on cleft sentences with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Ask whether the part you take as settled really is | A notes app | The settled and the open part | | SEO | Find queries like is it X that and answer the open part | Search Console queries containing is it | What searchers take as settled | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:"is it"` | Pages for is it questions | *Who benefits from cleft sentences, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Answers the open part of is it X queries | Direct answers to focused questions | | Customer support | Answers what customers actually doubt | Faster help | | Readers | Get the part they wanted answered | Precision | ## What is presupposition cancellation? Presupposition cancellation is the removal of an assumption by context, as in he did not stop smoking, he never smoked. Some presuppositions can be cancelled more easily than others. A person can take back an assumption in the next turn, and a system should notice. *How to act on presupposition cancellation with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Correct your assumption in the next search | Google search | Results for the corrected question | | SEO | Look for query pairs where searchers take back an assumption | Search Console, queries of the same page over a week | Assumptions people drop | | Your site | Check your own domain; replace example.com with it | `site:example.com "if not" OR "otherwise"` | Pages that cover the case without the assumption | *Who benefits from presupposition cancellation, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | SEO | Notices when searchers take back assumptions | Pages for the corrected question | | Content team | Covers the case without the assumption | Visitors who changed their mind stay | | Readers | Find content after correcting themselves | No dead ends | ## What is a pragmatic presupposition in relation to user intent? A pragmatic presupposition is an assumption that belongs to the speaker, the belief they take to be shared, as Robert Stalnaker described it. It depends on the context of use, beyond the sentence.

A semantic presupposition is a condition a sentence itself places on its truth. It is a property of the sentence, independent of who utters it. The two kinds together separate what the words assume from what the person assumes. *How to act on semantic presuppositions with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Check what the words of your query assume regardless of you | A notes app | Assumptions in the wording | | SEO | Reword titles whose words assume more than the page means | Search Console titles | Titles without unintended assumptions | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:"when will" OR intitle:"why did"` | Titles whose wording assumes something | *Who benefits from semantic presuppositions, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | SEO | Rewords titles that assume too much | Titles that attract the right visitors | | Content team | Checks wording for built-in assumptions | Precise pages | | Readers | Read titles that assume only what is meant | Trust | ## What is Stalnakerian common ground in a conversation? Stalnakerian common ground is Robert Stalnaker's formal model of common ground as the set of propositions the participants accept for the purposes of the conversation. Each assertion updates the set. It gives shared assumptions a structure a system could track. *How to act on conversational common ground with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Keep a note of what a chat assistant has already accepted from you | A notes app, the chat history | Assumptions that carry through the dialogue | | SEO | Check follow-up questions on a page for assumptions set earlier in the text | The page itself | Sections that rely on earlier assumptions | | Your site | Check your own domain; replace example.com with it | `site:example.com "as mentioned above"` | Pages that rely on earlier context | *Who benefits from conversational common ground, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Checks later sections for earlier assumptions | Pages that make sense when entered mid-way | | SEO | Keeps passages self-contained | Passages that work in answer engines | | Readers | Understand a section on its own | Faster help | Also discussed at [https://plato.stanford.edu/entries/assertion/](https://plato.stanford.edu/entries/assertion/#:~:text=For%20Stalnaker%2C%20the%20common%20ground%20is%20a%20set%20of%20propositions) ## What is a counterfactual conditional in a search query? A counterfactual conditional considers what would be true if something false were true, as in if I had started earlier, would I have ranked. It presupposes that the antecedent is false. A query of this kind asks about a possibility and should be answered as one. *How to act on counterfactual conditionals with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Treat what-if answers as scenarios | The page itself | Possibilities labelled as such | | SEO | Answer would-have queries as scenarios with their limits | Search Console queries with would or if I had | Questions about possibilities | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:"what if" OR intitle:"would"` | Pages for counterfactual questions | *Who benefits from counterfactual conditionals, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Answers what-if queries as scenarios | Visibility for what-if queries | | Legal and compliance | Labels scenarios as scenarios | No false promises | | Readers | Understand possibilities as possibilities | Realistic expectations | ## What is implicit query intent? Implicit query intent is the purpose a query does not state, including the assumptions behind it. It lives beyond the surface words. Reading only the words misses the part the person took for granted. *How to act on implicit query intent with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Add the purpose to your query | Google search | Results for the purpose | | SEO | Group queries by the unstated purpose behind them | Search Console export and Google Sheets | Purposes the page must serve | | Your site | Check your own domain; replace example.com with it | `site:example.com "so that you can"` | Pages that state purpose | *Who benefits from implicit query intent, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | SEO | Groups queries by unstated purpose | Pages built for purposes | | Content team | States the purpose a page serves | Visitors who find the right page | | Readers | Get content for their purpose | Relevant results | ## What is conversational search with stated assumptions? Conversational search lets a person search in several turns, as a dialogue. Assumptions can be stated, questioned and corrected along the way. A single query cannot do that, and a conversation can. *How to act on conversational search with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Tell a chat assistant your assumption and ask it to check it | Free tiers of chat assistants | An assumption questioned | | SEO | Check how chat assistants answer your main queries and whether they correct assumptions | Free tiers of chat assistants | Where your content could supply the correction | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:faq` | Question pages that could serve conversations | *Who benefits from conversational search, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | SEO | Checks how assistants answer main queries | Content that supplies corrections | | Content team | Writes answers that question assumptions | Citations in conversational answers | | Readers | Get assumptions checked in dialogue | Better answers | ## What is a clarification question from a search system? A clarification question is a question a system asks back to resolve what a person means. For a false or unclear presupposition, it is the only honest reply. It is also what a publisher can ask on a page, which is the idea of Supervised Search. *How to act on clarification questions with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Answer clarifying prompts instead of skipping them | Search and assistant prompts | Results for what you mean | | SEO | Add one clarifying question to pages with ambiguous or loaded queries | The page itself, Microsoft Clarity to watch the answers | Visitors routed by their actual need | | Your site | Check your own domain; replace example.com with it | `site:example.com "which of these" OR "are you looking for"` | Pages that ask back | *Who benefits from clarification questions, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Product team | Adds a clarifying question to ambiguous pages | Visitors routed to their need | | Content team | Writes the answer paths | Longer, better visits | | Readers | Are asked what they mean | Search that ends on the page | Also discussed at [https://arxiv.org/abs/1907.06554](https://arxiv.org/abs/1907.06554#:~:text=systems%20can%20improve%20user%20satisfaction%20by%20proactively%20asking%20questions%20of%20the%20users%20to%20clarify%20their%20information%20needs) ## What is the question under discussion behind a query? The question under discussion is a model by Craige Roberts in which every utterance addresses a question the conversation is trying to answer. Questions form a tree of larger and smaller goals. A query is a node in such a tree, and its place decides what counts as an answer. *How to act on the question under discussion with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Write the larger question your query belongs to | A notes app | What would count as an answer | | SEO | Map each query to the larger question it serves | Search Console and Google Sheets | Answers that fit the larger question | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:"complete guide"` | Pages for the larger question | *Who benefits from the question under discussion, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | SEO | Maps queries to larger questions | Pages for whole goals | | Content team | Writes for the larger question | Visitors whose goal is served | | Readers | Get answers that fit their larger aim | Progress | ## What is epistemic stance in a searcher's query? Epistemic stance is the way a speaker signals how certain they are, through words such as surely, maybe or I think. A query can be firm or tentative about its assumption. The same words with a different stance need a different answer. *How to act on epistemic stance with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Say how sure you are in the query, such as is it true that | Google search | Answers that address doubt | | SEO | Separate firm and tentative queries and answer doubt with evidence | Search Console custom regex filter for really, true, maybe | Doubt the page must address | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:"really" OR intitle:"true"` | Pages for doubtful queries | *Who benefits from epistemic stance, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Answers doubt with evidence | Visibility for really and true queries | | Customer support | Recognises doubt in questions | Reassuring replies | | Readers | Get doubt addressed | Confidence | ## What is pragmatic failure in search results? Pragmatic failure is a misunderstanding that comes from mismatched assumptions, beyond wrong words. Jenny Thomas described it in 1983. A result that fits the keywords and misses the assumption produces exactly this failure. *How to act on pragmatic failure with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | When results match words but miss the point, rephrase the assumption | Google search | Results for your real question | | SEO | Find queries with impressions and no clicks where the assumption differs | Search Console, high impressions and low click-through rate | Mismatched assumptions | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:"your topic"` | Pages to check for mismatched assumptions | *Who benefits from pragmatic failure, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | SEO | Finds impressions without clicks from mismatched assumptions | Higher click-through rates | | Content team | Aligns the page with searchers' assumptions or corrects them | Satisfied visitors | | Readers | Get results that fit their real question | Less frustration | ## What is a task-oriented dialogue system that tracks assumptions? A task-oriented dialogue system helps a person complete a goal, such as booking or troubleshooting, through conversation. It has to track what the person assumes and what is still open. Presupposition handling is part of getting the task done. *How to act on assumption tracking in dialogue with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Correct a support bot as soon as it assumes something wrong | The site's chat | The right path | | SEO | Read chat logs for wrong assumptions and fix the content behind them | Chat or support logs, Google Sheets | Assumptions that derail tasks | | Your site | Check your own domain; replace example.com with it | `site:example.com inurl:help` | Help content the dialogue relies on | *Who benefits from assumption tracking in dialogue, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Customer support | Fixes content behind wrong bot assumptions | Tasks completed in chat | | Product team | Improves the dialogue flow | Fewer abandoned tasks | | Readers | Complete tasks without derailing | Time saved | Described in a Google patent: [https://patents.google.com/patent/US8606568B1/en](https://patents.google.com/patent/US8606568B1/en#:~:text=transmitting%20a%20disambiguation%20request%20to%20an%20application%2C%20wherein%20the%20disambiguation%20request%20identifies%20the%20pronoun) ## What is doxastic commitment of a searcher? Doxastic commitment is the commitment a person takes on to believing something. Accepting a presupposition as true and merely going along with it for the moment are different commitments. A searcher may entertain an assumption without holding it. *How to act on doxastic commitment with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Mark an assumption as tentative in your notes | A notes app | Beliefs you have not committed to | | SEO | Avoid wording that forces readers to accept an assumption | The page itself | Readers who can keep an open mind | | Your site | Check your own domain; replace example.com with it | `site:example.com "obviously" OR "clearly"` | Wording that presses commitment | *Who benefits from doxastic commitment, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Avoids wording that presses commitment | Readers who trust the page's fairness | | Legal and compliance | Avoids manipulative wording | Compliance | | Readers | Keep an open mind | Autonomy | ## What is an assertion in a query? An assertion is the main claim an utterance puts forward, as distinct from what it presupposes. Answers address the assertion by default. For a query, the presupposed background can matter more than the asserted question. *How to act on assertions with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Separate the question you ask from the background you assume | A notes app | Both parts of the query | | SEO | Answer the assertion and address the background where it matters | The page itself | Answers that cover both | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:"how to"` | Pages that answer the asserted question | *Who benefits from assertions, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Answers the question and addresses its background | Complete answers | | SEO | Covers both parts of queries | Pages that satisfy fully | | Readers | Get both parts answered | No follow-up search | ## What is a contextual defeater for a query's assumption? A contextual defeater is information in a situation that undermines a belief that would otherwise be justified. It comes from epistemology. A new fact can defeat the assumption a query rested on, and the answer has to change with it. *How to act on contextual defeaters with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Check whether something new has changed the basis of your question | Google News, official announcements | Facts that undo the assumption | | SEO | Update pages when a new fact defeats the assumption of their main query | Google Alerts, Search Console queries over time | Pages that stay correct | | Your site | Check your own domain; replace example.com with it | `site:example.com before:2024-01-01 intitle:"your topic"` | Older pages that new facts may undermine | *Who benefits from contextual defeaters, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Updates pages when new facts appear | Pages that stay correct | | Legal and compliance | Removes outdated statements | Lower risk | | Readers | Get current information | Sound decisions | ## What is an epistemic modal in a tentative query? An epistemic modal, such as might, must or probably, expresses how possible or necessary something is given what a speaker knows. It marks a query as tentative. Tentative queries and certain ones should not receive the same confident answer. *How to act on epistemic modals with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | Searcher | Use might or could in your query when you are unsure | Google search | Answers that respect uncertainty | | SEO | Match the certainty of the answer to the evidence | The page itself | Answers that are not overconfident | | Your site | Check your own domain; replace example.com with it | `site:example.com intitle:"can" OR intitle:"might"` | Pages for tentative questions | *Who benefits from epistemic modals, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Matches certainty to evidence | Credibility with careful readers | | Legal and compliance | Avoids overconfident claims | Lower risk | | Readers | Get answers as sure as the evidence | Calibrated trust | ## Why do presuppositions matter commercially? A query with a false or narrow assumption leads a system to answer inside that assumption. The person who typed headache tablet gets pharmacy results and never hears of acupressure. Every business whose offer lies outside the assumption of a query is invisible to that query. *How to act on presuppositions in business with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | SEO | List offers of yours that lie outside the assumption of your main queries | Search Console queries and Google Sheets | Demand the assumption hides | | Your site | Check your own domain; replace example.com with it | `site:example.com "alternative to"` | Pages that reach people outside the assumption | *Who benefits from presuppositions in business, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Management | Finds offers hidden outside query assumptions | Demand competitors never see | | Sales | Reaches people who assumed another solution | New customers | | Readers | Learn about better solutions | Better outcomes | ## What should a page do about presuppositions in queries? Name the assumption and answer it as well as the question. A page can say what a query takes for granted, correct it where it is false, and ask back what the person actually wants. That is the clarification question moved onto the page, the idea of Supervised Search. *How to act on presuppositions on a page with free means* | Who | What to do | Free means | What it shows | | --- | --- | --- | --- | | SEO | Name the assumption, correct it where false, and ask back what the person wants | The page itself, Microsoft Clarity | Visitors served beyond the assumption | | SEO | Measure which answer to the clarifying question people choose | Google Analytics 4 events | How many searchers held another assumption | | Your site | Check your own domain; replace example.com with it | `site:example.com "what do you actually want"` | Pages that ask back | *Who benefits from presuppositions on a page, and how it pays off in search results* | Who benefits | In everyday use | How it pays off | | --- | --- | --- | | Content team | Names, corrects and asks back | Visitors served beyond the assumption | | Product team | Measures clarifying answers | Insight into hidden needs | | Readers | Are asked what they really want | Search that ends on the page | [Search intent](https://www.searchresultoptimization.com/digital-marketing/search-intent/) First published 2026-09-14.
