Schema Preview
A free Chrome and Firefox extension that validates schema.org structured data on any page.
What it does
Open any page, click the extension, and see its structured data laid out clearly: which types are present, whether the JSON-LD is valid, and where it’s likely to fall short of a rich result. No copy-pasting URLs into three different validators. No guessing.
Why we made it
We kept hitting the same wall on projects — markup that validated in one tool, failed in another, and showed nothing in search. We wanted one fast, honest read on a page’s structured data. So we built it, and then we kept using it.
Install it before you email us
That’s genuinely the point. You can evaluate how we build before you ever start a conversation. If the tool is good, the rest of the work is built by the same hands.
