Structured data helps search engines understand a page and can make it eligible for enhanced results, but it does not guarantee them, and Google says no special markup is needed for its AI features. Here are five beliefs that come up often, checked against Google's own pages.
Myth: markup guarantees rich results
Fact: Google says structured data "can enable" enhanced results and "might encourage" interaction. Markup can also be ineligible when required properties are missing or guidelines are not followed. Treat it as eligibility, not a promise.
Myth: more markup is better
Fact: Google says complete, accurate recommended properties matter more than adding many incomplete ones. A small correct block beats a sprawling one with gaps.
Myth: you can mark up things the page does not show
Fact: Google says to mark up only information users can see on the page, even if the hidden information is accurate. It also says not to create blank pages just to hold markup. Spammy or non compliant markup can lead to a manual action, which may cause Google to ignore the structured data.
Myth: you need special schema for AI answers
Fact: Google's AI features documentation says you do not need new machine readable files, AI specific text files, markup, or special schema.org structured data. Any markup you use should match visible text.
Myth: a passing test means it works
Fact: The Rich Results Test is for validation during development. After release, Google recommends watching the Rich result status reports in Search Console, because templating or serving problems can break markup later. URL Inspection shows whether Google found the data on a specific page.
A practical routine
- Decide which Google documented feature you are targeting. If there is none, markup may still help understanding but expect no visible change.
- Generate markup from the same data that renders the page, so the two cannot drift.
- Test one page of each template.
- Monitor after every template release.
- Measure impact the way Google suggests: compare similar pages with and without markup in the Performance report.
Mind the retired features
Features come and go. Google's FAQ rich result documentation now carries a notice that the feature stopped appearing in Search from 7 May 2026. See what to do with FAQ markup now. Before investing in any markup, read the current documentation page for that feature.
Quick check
Is JSON-LD required?
No. Google supports JSON-LD, Microdata and RDFa. It recommends JSON-LD for ease of maintenance.
Does Google use schema.org as the final authority?
Google says its own documentation is authoritative for Search behavior, even though most vocabulary comes from schema.org.
