Structured Data Tester (Schema.org / JSON-LD)
Check your website's structured data and find out whether it's ready to earn rich snippets in Google Search and get cited by AI-powered search engines.
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.
Detailed guide in the help centerFrequently 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.
