Free Schema Markup Checker for Any Page
See which common ecommerce JSON-LD types were detected in a fetched page.
Enter a page URL to list the JSON-LD types exposed in the fetched HTML. The checker flags common ecommerce types for inspection; a missing type is not always an error, and a present type is useful only when it accurately matches visible content.
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 JSON-LD blocks, and lists the schema.org types it found. It then reports whether common ecommerce types—Product, AggregateRating or Review, FAQPage, BreadcrumbList, and Organization—were detected. Detection is a markup observation, not a ranking or citation verdict.
Why does it say my reviews are missing when I have reviews?
A page can show reviews without exposing qualifying AggregateRating or Review JSON-LD in the fetched response, and dynamic rendering can also create detector misses. The result means the checker did not detect that markup; it does not mean search or AI systems cannot read visible reviews.
Is this the same as your full scan?
No. This checks one page's schema. The full StoreCited scan also audits visible FAQ and comparison content, reviews, crawlability, and brand-entity signals, then models buyer-question and category-peer hypotheses for independent validation.
