Schema Markup Validator

Verify your structured data before search engines do

Structured data in JSON-LD tells search engines exactly what a page represents, a product, a recipe, an FAQ, and can unlock rich results. But it only works if it is valid. This validator checks your JSON-LD for the errors that stop it being used, so you can fix them before relying on it.

Invalid structured data simply does nothing

The frustrating thing about broken structured data is that it fails silently. A malformed JSON block, a missing required property, or the wrong type name does not throw a visible error; the rich result just never appears, and you are left wondering why. Validating catches the syntax errors and missing pieces that would otherwise cause search engines to quietly ignore the markup.

Rich results are earned, not guaranteed

Valid structured data makes a page eligible for enhanced listings, stars, prices, FAQ dropdowns, but eligibility is not a promise, since search engines decide when to show them. What is certain is that invalid markup is ineligible. Getting the JSON-LD correct is the necessary first step. The validation runs in your browser, so your markup is not uploaded.
