Free Schema Markup Checker for Any Page
See which JSON-LD types a page exposes — and which AI-critical ones are missing.
Enter a page URL and we'll fetch it and list the JSON-LD structured data it exposes to crawlers — then flag the AI-critical types (Product, Review, FAQ, Organization) that are missing.
Tip: paste a product page URL for the most useful read.
Frequently asked questions
What does this checker do?
It fetches the page's HTML, extracts every JSON-LD block, and lists the schema.org types it found. Then it flags whether the types AI relies on most — Product, AggregateRating/Review, FAQPage, Organization — are present or missing.
Why does it say my reviews are missing when I have reviews?
Many review apps render stars for shoppers but never output AggregateRating JSON-LD, or load it via JavaScript crawlers don't execute. That's the single most common AI-visibility gap we see — visible reviews, invisible schema.
Is this the same as your full scan?
No. This checks one page's schema. The full StoreCited scan also grades buyer-question coverage, comparison content, reviews, crawlability, and brand entity, then models competitors and gaps — your complete AI Visibility Score.
