Read the schema.org data on any page or paste your own JSON-LD, find missing fields, and see which Google search features it can show.
We read JSON-LD, microdata and RDFa — or check code before you publish.
Errors stop a search feature; warnings are recommended fields.
Open each block in the tree and copy the JSON-LD.
An error means a required field is missing or wrong, so Google can’t use that block for a search feature. A warning is a recommended field that would make the result richer.
Valid data makes a page eligible, not guaranteed. Google also considers page quality and the search, and some features (like FAQ) are limited to certain sites.
JSON-LD in a script tag. It’s what Google recommends and the easiest to maintain.
