Short answer: paste a page URL. We find its JSON-LD and microdata, match each item to the Google feature it could earn, such as Product snippet, Recipe or Breadcrumb, and check it against the properties Google’s guide for that feature marks as required. Features Google has stopped showing are labelled, with the date.
What each result means
- Required properties present. The item has everything the guide requires, so it could be eligible. Google’s general structured data guidelines add that correct markup doesn’t guarantee a rich result.
- Missing required properties. An item without them isn’t eligible. We name each one, and list the recommended properties too.
- Google no longer shows this. The markup can still be valid, but the feature has left Search.
What Google has stopped showing
Google’s structured data gallery lists the features that exist today. These are gone or going, from Google’s own documentation updates:
- FAQ: not shown since May 7, 2026, and the guide was removed on June 15, 2026. From 2023 it was limited to well-known government and health sites.
- How-to: removed from desktop on September 13, 2023, after mobile earlier that year.
- Sitelinks search box: removed on November 29, 2024.
- Course info, estimated salary, learning video, special announcement and vehicle listing: removed in September 2025.
- Fact check (ClaimReview): being phased out, and dropped from the Rich Results Test on September 9, 2025.
- Dataset: Google clarified in November 2025 that this markup is used by Dataset Search, not by Google Search results.
Limits worth knowing
We read the HTML your server sends. Markup that JavaScript adds after the page loads isn’t in it, while Google renders a page before reading it, so for a page that builds its markup in the browser use Google’s Rich Results Test. We read JSON-LD and microdata and count RDFa without judging it. Some features need more than markup: vacation rentals need an invitation from Google, the movie carousel needs a list and is for mobile, and events must be in a physical place and open to the public. Each result card lists the limits Google states.
For a deeper pass on the markup itself, use the schema markup validator. To write the JSON-LD, start from the schema markup generator.
