Free Schema Validatorthat checks what Google shows today
Valid code is only the first check. This free tool also checks current Google feature rules, compares your markup with the page people see, and helps you understand the entities behind it.
- Paste anything. A URL, full HTML, JSON-LD with or without script tags, Microdata or RDFa.
- Dated Google rules. Separate valid schema.org vocabulary from Google rich result support. Retired features are not syntax errors.
- Corrected code, free to copy. Evidence-led fixes, with no invented ratings, prices, logos or placeholder values.

ONE FREE CHECK, FIVE LAYERS
What this validator checks beyond syntax
Four diagnostic layers contribute to the explanatory score. The optional search benchmark adds context, not points. Checks that cannot be verified are marked unavailable.
2
Eligible today
Google feature requirements and retirement dates, kept separate from vocabulary validity. Eligibility never guarantees a rich result.
Dated rules in every report
3
True to your page
Compare names, prices, authors, dates and ratings in your markup with available page evidence. Pasted code alone cannot verify visible content.
4
Clear entities
Inspect entities and their @id links. Multiple organizations, multiple types and external references can be legitimate; review the evidence before changing them.
5
Search benchmark
Add a keyword to compare markup on ranking pages. Page types are shown for context; blocked or unavailable pages are never passed off as verified.

Valid markup does not guarantee a rich result. Feature support and page eligibility are different questions.

Schema validation, without the guesswork
Is this schema validator really free?
Yes. The full report, findings and available corrected code are free to view, copy and download. You do not need an account, an email address or a credit card. Fair-use limits keep the tool available.
What can I paste into the validator?
Use a public HTTP or HTTPS page URL, or paste up to 200,000 characters of code. Code can be JSON-LD, script-wrapped JSON-LD, full HTML, Microdata or RDFa. Invalid JSON is diagnosed; we do not turn it into a made-up replacement.
Does a high score guarantee Google rich results?
No. The score is an explanatory heuristic across tested categories, normalized when some checks are unavailable. It is not a Google score, a ranking forecast or an eligibility guarantee. Google also considers content, policies, indexing and other signals.
Why are some checks unavailable for pasted code?
Code alone cannot prove what visitors see, whether a page is indexable, or what JavaScript renders. Submit the page URL for those checks. Network restrictions, robots rules and rendering availability can still limit what we verify.
Will the tool invent missing ratings or prices?
No. Corrected code only uses supported input and page evidence. Facts that need your confirmation stay in a separate action list, not as placeholders in code advertised as ready to copy.
Can I share a report or send it to my developer?
A successful saved report has an unguessable link that expires after 24 hours. Anyone with that link can view its contents, including code. The developer action opens a draft in your own email app; this tool does not claim to send it. No monitoring starts when you run a check.
