Free SEO tool

Structured data checker

Find the schema.org markup on a page, in JSON-LD, microdata or RDFa, and check every item for the properties Google requires.

Free and unlimited: does not use your weekly runs
Free, no sign-up.

What the checker tests

Every JSON-LD block is parsed; a block with a syntax error is ignored by search engines as a whole, so that is the first thing it reports. Every item, nested ones and @graph included, is listed with its type and properties.

For Product, Article, NewsArticle, BlogPosting, FAQPage, BreadcrumbList, Organization, LocalBusiness, Event, Recipe, VideoObject and JobPosting it checks the properties Google requires before it can show a rich result, such as a Product's name and offers, review or rating.

One limitation

The checker reads the HTML your server sends. Structured data that JavaScript adds after the page loads, as some plugins and tag managers do, is not seen. Google's own Rich Results Test does run JavaScript.

Does this tool count towards my free runs?
