Schema Markup Checker
See every piece of structured data on a page, which ones are broken and which properties Google still needs.
How to Use the Schema Markup Checker
- Enter the page with the markup, like your homepage or a product page.
- We pull every JSON-LD block plus any microdata and RDFa.
- Each item is checked for the properties Google requires or recommends for that type.
The Errors We See Most
The most common problem is invalid JSON, usually a missing comma or a stray quote from copying code out of a word processor. Google skips the whole block when that happens, so nothing in it counts.
Next is duplicate markup. A theme adds a LocalBusiness block, an SEO plugin adds another and the 2 disagree on hours or phone number. Keep 1 complete version.
Valid Isn't the Same as Eligible
Passing here means the markup is readable and has the properties Google looks for. Google still decides whether to show a rich result, and some types, like FAQ dropdowns, now appear for very few sites. Use Google's Rich Results Test to confirm eligibility for a specific feature.
Frequently Asked Questions
Which schema should a local business use?
Use the most specific LocalBusiness type that fits, like Plumber, Dentist or ExerciseGym, with your name, address, phone, hours and website. Our schema generator picks the type for you.
Is JSON-LD better than microdata?
Google reads both. JSON-LD is easier to add and maintain because it sits in 1 block instead of being woven through your HTML, which is why Google recommends it.
Why doesn't my page show stars in Google?
Review stars need genuine reviews of the item on the page, and Google doesn't show them for a business reviewing itself on its own site. Valid markup alone doesn't guarantee stars.
