Free Schema Debugger โ€” Score Your Structured Data 0 to 100

Most schema validation tools just tell you whether your JSON-LD is valid syntax. Ours tells you whether it is actually good โ€” scoring each schema block 0-100, identifying every missing required property, every recommended field you are skipping, and every AEO issue that stops AI search engines from citing your business. Free to check. No account needed to run a basic audit.

What our schema debugger checks

Our debugger fetches your live page, extracts every schema block on it, and analyses each one against Google rich result requirements, schema.org specifications, and AEO (Answer Engine Optimisation) criteria for AI search engines.

For each block you get a score from 0-100, a colour-coded result (green 80+, orange 50-79, red below 50), a list of errors (required properties missing that block rich results), warnings (recommended properties missing that reduce your score), and AEO issues (fields AI engines specifically use to cite and recommend your business).

Grey properties marked as "worth including" are optional but improve entity authority โ€” things like VAT ID, LEI code, foundingDate and knowsAbout that build your knowledge graph presence.

How it differs from Google Rich Results Test

Google Rich Results Test tells you whether your page is eligible for a specific rich result type โ€” that is its entire job. It does not score your schema, does not identify missing recommended properties, does not check AEO signals, and does not tell you what to fix.

Our debugger gives you a complete picture: eligibility, score, every missing field, specific fix instructions for each issue, and a comparison of what your schema could look like after using our generator to improve it.

How to use the schema debugger

Go to the Schema Debugger and either paste your website URL (it fetches the page automatically) or paste your JSON-LD directly into the paste box. Click Analyse.

In about 5 seconds you get your full results. Each schema block on your page is shown separately with its own score and issue list. The overall score is an average across all blocks.

If you want to improve your schema, use the AI Schema Generator to regenerate it from your page URL, then run it back through the debugger to see your score improve.
