What is an Open Graph checker?
An Open Graph checker is a free tool that loads any web page, finds its og:meta tags (and the Twitter Card tags), and reports which are present or missing. It's an OG tag tester and open graph validator in one — paste a URL to check og tags in seconds, no signup.
Validate your Open Graph tags
Use it as an open graph validator / og meta tag checker: we list every tag with its content and flag the required ones — og:title, og:description, og:image, og:url and og:type. It's the quickest way to check og meta tags and catch missing open graph tags before you share a link.
Preview your social share
The built-in open graph previewrenders your og:image, title, description and domain into a share card — roughly how the link will look on Facebook, LinkedIn and X/Twitter. It's an opengraph preview and open graph test tool so you can see the result, not just the raw tags.
Why Open Graph tags matter
Open Graph tags control the title, description and image shown when your page is shared on social media. Rich, correct tags earn more clicks; missing or broken tags leave a plain, unappealing link. Checking them is a quick win for social traffic and brand presentation.
How to use the Open Graph checker

Click “Check Tags” — we fetch the live page and read its og/twitter tags.
Review the required-tag checklist, the full tag list, and the share preview.

An Open Graph checker is a free tool that fetches any URL, finds every og: meta tag (and the Twitter Card equivalents), reports which required tags are present or missing, and previews how the page will look when shared. It works as an OG tag tester and validator, no signup.
Paste the page URL into the Open Graph checker above and run it. We fetch the live HTML, list every og: and twitter: tag with its content, flag any missing required tags (og:title, og:description, og:image, og:url, og:type), and render a social share preview. That's the fastest way to check og tags.
The core tags are og:title, og:description, og:image, og:url and og:type. og:image is the most important for a rich preview — without it, shares fall back to a plain link. Twitter also reads these but twitter:card (e.g. summary_large_image) controls its layout.
Common causes of missing Open Graph tags: the tags aren't in the HTML <head>, og:image uses a relative or non-public URL, or the page is rendered client-side so crawlers don't see the tags. This checker shows exactly which tags are present so you can fix the gaps.
Yes. The Open Graph checker renders a preview using your og:image, og:title, og:description and domain — an open graph preview of roughly how the link will appear on Facebook, LinkedIn and X/Twitter when shared.
This tool checks and previews the Open Graph tags already on a page. To create the tags from scratch, use our Open Graph generator — paste your title, description and image and copy the ready-made meta tags into your <head>.
