Meta Tag & OG Checker
Check any page's SEO meta tags, Open Graph and Twitter Card data. See exactly how the link renders when shared, and get a fix for every missing or broken tag.
What this meta tag checker tests
The checker fetches your page like a crawler, follows redirects to the final URL, and reads the head of the document: the title tag and its length, the meta description, the canonical URL, the robots directive, every Open Graph property and the Twitter Card tags. It then renders the same share preview Facebook, LinkedIn and X will build from those tags, so what you see here is what your audience sees in their feed.
One check most tools skip: the og:image is actually requested, not just read. A declared image that returns 404, 403 or an HTML error page is the most common reason shares render without a picture, and it is invisible unless something tries to load the file. Fix the findings, re-run the check, then force the social platforms to re-scrape with their debugger tools.
Meta tags FAQ
What are Open Graph tags?
Open Graph tags are meta tags (og:title, og:description, og:image, og:url) that control how a link looks when shared on Facebook, LinkedIn, WhatsApp, Slack, Discord and most other apps. Without them, platforms guess, and shared links often render as bare text with no image.
Why does my link show no image when shared?
Almost always one of three causes: the og:image tag is missing, the image URL returns an error or is blocked for external requests, or the platform cached an old version of your page. This checker verifies the tag exists and that the image actually loads, which covers the first two.
What size should an og:image be?
Use 1200 by 630 pixels. That ratio (1.91:1) renders as a full-width card on Facebook, LinkedIn and X with summary_large_image, and stays sharp on high-density screens. Keep the file under about 1 MB so platforms fetch it quickly.
Do I need separate Twitter Card tags?
Mostly no. X falls back to Open Graph tags for the title, description and image. The one tag you should add is twitter:card with the value summary_large_image, otherwise X may render a small thumbnail card instead of the full-width image.
How do I refresh what Facebook or LinkedIn shows for my link?
Platforms cache link previews aggressively. After fixing your tags, run the URL through the Facebook Sharing Debugger or LinkedIn Post Inspector to force a re-scrape. X refreshes its cache automatically within a few days.
Do meta tags affect Google rankings?
The title tag matters directly. The meta description does not affect ranking but controls your snippet and click-through rate. Open Graph tags do not influence rankings at all, but they decide whether social shares of your content look clickable or broken, which drives the traffic that earns links.
