Open Graph and social preview checker

When you share a link on social media, it pulls the title, description and image from Open Graph tags. Enter an address to see how the preview looks and what is missing.

What the Open Graph checker shows

When you share a link on Facebook, Telegram, LinkedIn, Slack or X, the service downloads the page and builds the preview from its meta tags: og:title, og:description, og:image and, for X, twitter:card. The checker reads the same tags from the page's HTML, draws a preview of the card and lists what is missing.

It also checks the plain title and meta description that Google shows in search results, and the canonical link. Titles longer than 60 characters and descriptions longer than 160 get cut off, so the tool flags them.

How to read the result

og:image: the tag that matters most for clicks. Use an absolute https address, ideally an image of 1200 by 630 pixels.
No og:title or og:description: networks fall back to the page title or random text from the page.
twitter:card: the value summary_large_image gives a large picture preview on X; without it the card is small.
Canonical: the address that search engines and many networks treat as the main one for this page.

Frequently asked questions

I fixed the tags, but Facebook or Telegram still show the old preview. Why?: They cache previews. For Facebook, open the Sharing Debugger and press Scrape Again; for Telegram, send the link to @WebpageBot to refresh it. Our check always reads the live page.
What size should og:image be?: 1200 by 630 pixels (1.91:1) works on all major networks. Keep the important part in the center, because some apps crop the picture to a square.
Do Open Graph tags affect Google rankings?: Not directly. They affect how your links look and how often people click them when shared, which matters for traffic from social networks and messengers.
