Required fields are this generator’s minimum, not complete Google rich-result validation. Use accurate content visible on your page; do not invent ratings.

How to use this tool

Select a schema type, enter truthful page details and review required-field errors. Export JSON or script markup, integrate it into the matching page and validate the deployed result separately.
