JSON-LD Scanner
The JSON-LD Scanner shows the structured data a page exposes to search and AI crawlers. Enter a public page URL and the scanner fetches its HTML, extracts every application/ld+json block, and shows the exact schema types, @id values, and parse errors. Use it to confirm whether a page is sending Organization, Article, FAQPage, Product, or BreadcrumbList markup before you troubleshoot rankings or AI visibility.
We fetch one public page and use a rendered fallback only when direct access is blocked.
How to use it
-
1
Enter the exact page URL you want to audit.
-
2
Review the source label to see whether the scan used the direct response or a rendered fallback.
-
3
Open each JSON-LD block to inspect the schema types, @id values, and raw markup.
-
4
Fix malformed blocks or missing page-specific schema, then scan the page again.
FAQ
What does this scanner check?
It checks whether the page contains JSON-LD script blocks, whether each block parses as JSON, which schema types appear, and which @id values are present. It does not run a remote Schema.org or Google rich result validation.
Why might the scanner show no JSON-LD?
The page may not include JSON-LD in the HTML response, may block automated access, or may inject schema later with JavaScript. Check the page in your browser as well when client-side code creates the markup after load.
Which JSON-LD types should SEO marketers look for?
It depends on the page. Organization and WebSite help identify the brand, BreadcrumbList clarifies page hierarchy, Article or BlogPosting describes editorial content, FAQPage exposes question-and-answer content, and Product or Offer describes commercial pages.
