An Open Graph checker instantly scans any URL and shows you exactly what og:title, og:description, and og:image tags are set — so you can fix social share previews before anyone sees a broken link card.
Every time someone shares a link on Facebook, LinkedIn, Twitter, Discord, WhatsApp, or Slack, the platform reads your OG tags to build the preview card. If those tags are missing, wrong, or pointing to a broken image, your shared link looks unprofessional — or worse, invisible. An OG checker lets you catch these problems before your audience does.
Open Graph tags are a small set of HTML meta tags that control the visual preview when your URL is shared on social media. The protocol was created by Facebook in 2010, but it is now used by virtually every major platform.
The four essential OG tags every page needs:

property attribute is used (not name): <meta property="og:title" content="Your Title">OG tags are a universal standard, but every platform interprets them slightly differently. Here is what to expect:
Facebook created the Open Graph protocol, so it has the most complete support. Reads all standard OG tags. Recommended image: 1200 x 630px. Caches previews aggressively — use the Sharing Debugger to force a refresh. Requires a Facebook account to use the debugger. If og:image is missing, Facebook grabs the largest image on the page, which is often your logo or a random sidebar image.
LinkedIn reads og:title, og:description, and og:image. Recommended image: 1200 x 627px (nearly identical to Facebook). LinkedIn's Post Inspector lets you preview and refresh cached previews. LinkedIn is stricter about image quality — blurry or low-resolution images may not render in the preview at all.
Twitter uses its own twitter:card meta tags first, then falls back to OG tags if twitter-specific tags are missing. For large image cards, set twitter:card to summary_large_image and use an 800 x 418px image (or 1200 x 630px works too). Twitter's built-in Card Validator was deprecated in 2022 — use an external checker to test your cards now.
Discord reads OG tags and renders rich embeds for shared links. It supports og:video for inline video playback and uses og:site_name prominently in the embed header. Discord also reads theme-color meta tags to set the embed sidebar color. Image previews are generous — large images display well in Discord chat.
WhatsApp reads og:title, og:description, and og:image for link previews in chats. Images are heavily compressed. Caching is aggressive and there is no official way to clear it — you may need to wait hours or days for updated previews to appear. For best results, use high-contrast images that survive compression.
Most WordPress SEO plugins (Yoast, Rank Math, All in One SEO) add OG tags automatically. Check your page source to verify they are present. Common issue: some themes also inject OG tags, creating duplicates. Use our OG Checker to verify only one set of tags exists.
Webflow has built-in OG tag fields in the page settings panel (under Open Graph Settings). Fill in the OG Title, OG Description, and OG Image fields. Webflow handles the HTML automatically. After publishing, run the URL through an OG checker to confirm everything rendered correctly.
In Next.js, add OG tags in your page's Head component or using the new metadata API (App Router). Common mistake: OG tags are present in client-rendered HTML but not in the server-rendered output. Social media crawlers do not execute JavaScript — your OG tags must be in the initial HTML response. Test by viewing page source (not inspect element) or using an OG checker.
This is the honest limitation section. Our OG checker (and any third-party tool) reads your tags and shows you what platforms will see. But there is one thing only Facebook's own debugger can do: clear Facebook's cache.
When you update OG tags on your page, Facebook continues showing the old preview until its cache expires. The only way to force an immediate refresh on Facebook is to use the "Scrape Again" button in the Facebook Sharing Debugger. This requires a Facebook account.
Our recommendation: use a third-party OG checker (like ours) to validate your tags are correct, then hit "Scrape Again" on Facebook's debugger to clear the cache. Two steps, two different tools, best results.
Check your Open Graph tags right now — paste any URL and see exactly what social platforms will display.
