A free schema markup validator that checks your JSON-LD against Google's rules for each type, and shows what to fix.
5.0(1 rating)Check the schema markup on any page, or paste your code. Every type is checked against Google's rules, with what to fix.
Schema markup tells Google what a page is: a person, a product, an article, an event. When it's wrong, Google ignores it.
This free schema markup validator checks the JSON-LD on any page, or code you paste, against Google's rules for each type, and shows what to fix.
Here's what it checks, what the results mean, and how to fix what it finds.
What is a schema markup validator?
A schema markup validator is a tool that reads a page's structured data and checks it against the rules search engines use.
Mine checks JSON-LD, the format Google recommends, type by type: what's required, what's recommended, and whether each value is in a form Google can read.
How to validate your schema markup
What the results mean
Every issue has 1 of 3 levels:
- Error – Google won't use the markup: broken JSON, a missing required field, or a date or number it can't read.
- Warning – allowed, but it costs you: a missing recommended field, a relative address, or a type Google no longer shows.
- Info – worth knowing, like a type this checker doesn't cover.
Each type also shows what Google does with it today: a rich result, a rich result with a condition, or nothing anymore.
How to fix schema errors
Fix errors first, since they stop Google from using the markup at all. Most are a missing field or a date in the wrong form.
Then add the recommended fields you can. My schema markup generator writes JSON-LD that passes every check here.

No, valid schema makes a page eligible, and Google decides whether to show a rich result.
Google's Rich Results Test shows which ones a page can get.
