Meta Tag and Open Graph Checker.

How to use it

Enter any page, not just a home page. Meta tags are per-page, and the pages that are wrong are almost never the home page — somebody looked at that one. It is the template-generated pages, the ones nobody has opened since launch, where the title is still “Untitled” or every page shares one description.

Check a competitor's page too. The tags are public, so this is a legitimate way to see how a page that outranks you is described, and whether the difference is the writing rather than anything technical.

How to read the result

Start at the top of the findings list, because it is ordered by consequence rather than by where the tag sits in the document. A noindex directive appears first for a reason: while it is there, nothing else on the list changes anything.

The preview above the findings is drawn at the pixel widths Google truncates at, not at a character count. That difference is not pedantry — a title of sixty narrow characters fits and a title of fifty-five wide ones does not, and the character count everybody quotes cannot tell them apart.

Treat the preview as the version shown when your description is the best answer to the query. Google rewrites descriptions on the majority of results to match what was actually searched for, and rewrites titles on a meaningful minority. Yours is most likely to survive on branded searches, which is exactly where it matters most.

What to do next

Fix anything marked as a failure first, then come back to the warnings. A missing viewport tag or a noindex is a different class of problem from a description that could be better written.

If several pages share a description, that is a template problem rather than a copywriting one. Find where the template writes the head and give it a per-page value; writing thirty descriptions by hand into a system that ignores them is a wasted afternoon.
