Share

What the tool checks

  • Detection of JSON-LD, Microdata, and RDFa formats
  • Schema types in use (Article, Product, FAQ, BreadcrumbList, Organization, and more)
  • Missing required properties for each schema type
  • Rich snippet eligibility (star ratings, prices, FAQ dropdowns)
  • GEO signals for AI search engines (ChatGPT, Perplexity, Gemini)

Why it matters

Structured data tells search engines what your content means — a recipe, a product, an article, a FAQ. This unlocks richer, more eye-catching search listings that drive higher click-through rates. It's also a critical factor for getting cited in AI-generated answers from tools like ChatGPT and Perplexity.

Frequently asked questions

What is structured data?

A standardized way (most commonly Schema.org markup in JSON-LD format) to describe your page's content in code so search engines can understand and represent it accurately.

Does structured data improve rankings?

It's not a direct ranking factor, but it unlocks rich snippets that boost click-through rates (CTR) and helps AI search engines correctly cite your content.

Which format should I use?

Google recommends JSON-LD embedded in your page's <head>. It's the easiest to maintain and the least error-prone approach.
