# Open Graph & Meta Tag Checker

Enter the address of a page and see the meta tags a crawler actually gets back: the title, the description, the canonical, the Open Graph set and the Twitter card, with a preview of the link card they produce and a list of what is missing. The page is fetched by us rather than by your browser, because a browser is not allowed to read another site.

This tool runs entirely in the browser. Nothing is uploaded, and no account is needed.

## How to use it

1. **Enter a URL.** Paste the full public address of the page you want to check, including https://.
2. **Read the tags.** See the title, description, canonical, Open Graph and Twitter card tags the page actually returns, with a preview of the card they produce.
3. **Fix what is missing.** Take the list of missing tags to the meta tag generator, paste the result into your page head, and check it again.

## Frequently asked questions

### Is the Open Graph checker free?

Yes, free and with no sign-up. Requests are rate limited per visitor so the fetcher stays available for everyone.

### Does this upload anything of mine?

No. You give it a public URL and our server fetches that URL. Nothing of yours is uploaded, and the page we fetch is read for a fixed list of tag names and then discarded.

### Why does it say no tags were found on a page that has them?

Almost always because the tags are added by JavaScript after load. Crawlers read the HTML the server sent, which is what this reads too, so tags written at runtime are invisible to both.

### Can it check a page behind a login or on my laptop?

No. It fetches as an anonymous visitor on the public internet, so a page behind a password, on a private network or on localhost cannot be reached.

### I fixed a tag but the preview on a social network has not changed.

Networks cache what they fetched. This checker reads your page live, so if it shows the new value the page is correct; use the network's own re-fetch tool to clear its copy.

### What do I do with what it finds?

Use the meta tag generator to build the block of tags you are missing, paste it into your page head, and re-check.
