Structured Data Checker

Enter a domain or website URL to analyse.

The Structured Data Checker loads a page and extracts the machine-readable markup that search engines and social networks rely on: Schema.org JSON-LD, microdata, Open Graph and Twitter Card tags. It shows what a crawler would actually find, which is often less than the template promises.

What the report contains

The source of the page is parsed and every relevant block is listed with its content, so you can see the entity types you publish and the exact text that will appear when the link is shared.

Every JSON-LD block with the Schema.org types it declares, nested types included
A warning when a JSON-LD block exists but does not parse as valid JSON
The number of microdata blocks marked with itemscope
All Open Graph properties with their values: title, description, image, type and address
All Twitter Card tags with their values

Anything missing from the list is not being read, whatever the plugin settings say: a JSON-LD block with a syntax error is invisible to search engines. Check that the entity types match the content of the page, that og:image points to a reachable file, and that the titles are the ones you want shown in link previews.

Frequently asked questions

What does the Structured Data Checker do?

It loads a page and extracts the machine-readable markup that search engines and social networks rely on: Schema.org JSON-LD, microdata, Open Graph and Twitter Card tags. You see exactly which types and values a crawler actually reads, which is often less than the template promises.

Why should I check my structured data?

Because structured data is what makes pages eligible for rich results such as stars, FAQs and product snippets. Broken or missing markup silently removes that eligibility, and a quick check reveals whether your CMS or theme really outputs what you configured.

Is the Structured Data Checker free to use?

Yes, the tool is completely free and requires no registration. Paste any URL — your own pages or a competitor's — and inspect the extracted markup as many times as you need.

Does valid markup guarantee rich snippets in Google?

No, valid markup makes a page eligible but does not guarantee rich results. Google decides per query whether to show them. The checker shows you what a crawler can read, which is the necessary first step toward earning those enhanced listings.
