Free Open Graph & Twitter Card Checker
Enter a page address and we read the title, description, canonical, Open Graph and Twitter card tags and flag anything missing or wrong.
Free, with no sign-up. Fair-use limits apply. To enforce them we keep the domain you enter and a scrambled form of your IP address for 30 days, as described in our privacy policy.
What is checked
The checker fetches the page and reads its title, meta description, canonical link and the Open Graph and Twitter card tags. It flags missing required tags, relative image addresses and descriptions that are too long or absent.
How to use it
Enter the full page address and press Check tags. You get a list of findings and a table of every tag found with its value.
Fixing what it finds
If tags are missing, build them with the Open Graph generator.
Frequently asked questions
Does this show how the card looks?
It checks the tags. For the exact card, use each platform’s own sharing debugger.
Why is my image flagged?
Images need an absolute address that is publicly reachable.
Can I check a page behind a login?
No, only public pages can be checked.
