What Is a Schema Markup Validator?
Schema markup only helps if search engines can read it. A trailing comma, curly quotes or a missing required property can make Google skip your markup. This validator checks both the code and the content: is the JSON valid, is the type known, and does it have the properties Google lists as required or recommended for that rich result.

Most common schema errors
- Trailing comma before
}or]. JSON does not allow it. - Curly quotes copied from Word or Docs. Use straight quotes only.
- Missing @context. Add
"@context": "https://schema.org". - Missing required property, like price on a Product offer.
- Content not on the page. Google wants markup to match what users see.
Validation Results Explained
| Result | What it means | What to do |
|---|---|---|
| Valid, has required properties | Google may show a rich result | Add recommended properties to make it richer |
| Missing recommended | Valid, but less complete | Add them if the info is on your page |
| Missing required | Not eligible for that rich result | Add the required properties |
| JSON error | The code cannot be read at all | Fix the syntax error shown |
| No rich result type | Valid schema.org, but Google has no rich result for it | Fine to keep. It still helps understanding. |

What the Validator Checks
1. Code checks: is the JSON valid, is there an @context and an @type, and are Microdata itemscope and itemprop used correctly.
2. Google checks: for types with a Google rich result, such as Product, Article, Breadcrumb, LocalBusiness, Event, Recipe, Video and JobPosting, the tool compares your properties with Google’s required and recommended lists. It also flags types Google no longer shows as rich results, such as HowTo and FAQ.
Is the Schema Markup Validator Accurate?
- Valid JSON-LD passes and broken JSON is caught
- Trailing commas and curly quotes are found
- Microdata items are read correctly
- Required property lists match Google's docs
- Retired rich results are flagged
Accuracy in plain words
Google’s own Rich Results Test is the final word for Google. Our tool explains problems in plain words and also covers types Google’s test does not, but Google can change its lists, so we review them every month.

Schema Markup Validator FAQ
What is a schema markup validator?
It is a tool that checks the structured data on a page. It finds JSON-LD and Microdata, tests the code and shows missing properties that Google needs for rich results.
Is this schema validator free?
Yes. It is 100% free, with no sign-up and no daily limit.
What is the difference between this tool and Google's Rich Results Test?
Google's test shows what Google can use for rich results. Our tool also explains JSON errors in plain words and checks code you paste before it goes live. Use both for the best result.
Why is my schema not showing in Google?
Common reasons are missing required properties, markup that does not match the page, a page that is not indexed, or Google choosing not to show a rich result for that search.
Can I check schema before publishing?
Yes. Paste your JSON-LD or HTML into the tool and run the check. No live page is needed.
Does this validator check Microdata?
Yes. It reads both JSON-LD and Microdata. JSON-LD is the format Google recommends.
What should I fix first?
Fix JSON errors first, then missing required properties. Recommended properties come last.
