Schema Markup Checker
Read the JSON-LD schema types a public page is actually sending and spot obvious implementation gaps.
See what structured data your page is actually sending.
Enter a public page and we will list the JSON-LD schema types we can identify in its response.
How to read the result
Why structured data is worth checking
Structured data gives search engines a machine-readable description of parts of a page. It can help them understand that a page describes a business, an article, a product or a software tool. It does not replace clear page content, and adding markup does not guarantee a special search result.
This checker reads the JSON-LD blocks that are visible in a public page response and lists the schema types it can identify. That makes it useful when you inherited a site, changed themes or added an SEO plugin and want to see what is actually being sent.
What to look for
Look for schema that matches the page. An article should not be marked up like a product simply because a plugin offered the option. A local business page should describe the real business. A tool page should describe the actual tool that a visitor can use.
Do not add markup just to have more markup
More JSON-LD is not automatically better. The useful question is simple: is the structured data accurate, visible in the page experience and supported by the content on that page? Keep the markup honest, then validate the implementation in your normal search tools.
