TL;DR

Eligibility is different from appearance
A rich result adds information or a special display to a search listing. Structured data can make a page eligible for supported features, but Google decides whether to show them. Passing a validation test is not proof of indexing, rankings or increased clicks.
Check the feature before investing
Choose a feature that suits the actual page and business. A genuine product page may qualify for product information when it meets the relevant requirements. Do not add unrelated markup merely because another website has a richer listing.
Some familiar displays have been retired. Google discontinued HowTo rich results in September 2023 and FAQ rich results in May 2026. Useful questions and instructions still belong on pages, but those markup types no longer earn their former Google display.
Diagnose a missing rich result
Check the relevant Google feature documentation, required fields and content policies. Confirm that the page is accessible, the markup describes visible information and the details are current.
Use the Rich Results Test for supported features, then inspect the URL and relevant enhancement reports in Search Console. Fix detected errors, but remember that a valid, indexed page can still appear as a normal listing. Do not change accurate content just to chase a display.
The current Search Gallery is the feature list to check before adding markup. Google says its AI search features have no extra technical or schema requirement. A rich-result test therefore cannot certify AI Overview citation eligibility or future appearance.
Review usefulness and outcomes
Price, availability or other relevant information can help a reader understand a listing. Whether it improves clicks or enquiries depends on the page, query and audience. Compare suitable periods and note content or tracking changes before attributing a difference to markup.
