Price and availability in a listing can filter the wrong visitor out. A higher conversion rate is not a documented, guaranteed effect of structured data.
What can markup change?
The mix of visitors, if a rich result shows a price, a stock state or a rating and some users self-select before the click.
What is this based on?
A higher conversion rate is not directly proven or guaranteed by structured data. Offer, landing page and search intent decide conversion. Changing the mix is not the same measurement as “schema raised conversion rate.”
