Open Graph Tag Tester, Preview Social Media Shares Free
This Open Graph tag tester checks any URL’s og: and Twitter card meta tags, then shows you exactly how the link will look when shared on Facebook, LinkedIn, and X. Spot missing or broken tags before you publish, no sign up needed.
How the Open Graph Tag Tester Works
This Open Graph tag tester fetches the raw HTML of any page you enter and parses out its Open Graph (og:) and Twitter Card meta tags, the exact fields Facebook, LinkedIn, and X read to build the preview card shown when a link is shared. It then renders a visual approximation of each platform’s card so you can catch problems before anyone else sees them.
Open Graph tags were introduced by Facebook in 2010 and have since become the de facto standard read by nearly every platform that generates link previews, including Slack, Discord, and iMessage, not just Facebook itself. Twitter maintains its own similar but separate tag set, which is why this tool checks both.
Everything is fetched and parsed live at the moment you run the check, through a public proxy service since browsers cannot read cross origin pages directly for security reasons.
What This Tool Does
How to Use It
Enter a URL
Type the full URL of the page you want to check, including https://.
Run the check
Click Preview Shares to fetch and parse the page’s meta tags live.
Compare previews
Check both the Facebook/LinkedIn and X preview cards for how they’ll appear when shared.
Fix what’s missing
Add any tags flagged as missing in the full tag table, then re-check after publishing changes.
Essential Open Graph Tags
<meta property="og:title" content="Your Page Title" />
<meta property="og:description" content="A short, compelling summary." />
<meta property="og:image" content="https://example.com/share-image.jpg" />
<meta property="og:url" content="https://example.com/page" />
<meta property="og:type" content="website" />
Place these inside the <head> of your page. The og:image should ideally be at least 1200 by 630 pixels for a sharp, properly cropped preview across platforms.
FAQ: Open Graph Tag Tester
Social platforms cache a link’s preview data after the first time it’s shared, sometimes for days or weeks, to avoid re-fetching your page every time someone posts the link. This tool always fetches your page fresh, so it will show your current tags correctly, but Facebook, LinkedIn, or X may still show an outdated cached version to other users until you force a re-scrape using that platform’s own debugging tool.
The widely recommended size is 1200 by 630 pixels, an aspect ratio of roughly 1.91:1, which displays sharply across Facebook, LinkedIn, X, and most messaging apps without awkward cropping. Keep the file size reasonable, under 5MB, and use JPG or PNG format for the broadest compatibility. Avoid putting critical text near the edges, since some platforms crop the image slightly differently.
Not strictly, X will fall back to your Open Graph tags if dedicated twitter: tags are missing, and this tool reflects that same fallback behavior in its preview. However, adding the twitter:card, twitter:title, twitter:description, and twitter:image tags explicitly gives you more precise control over how the card looks specifically on X, since it doesn’t always interpret Open Graph tags identically to Facebook.
The most common causes are the tag missing entirely, the image URL being a relative path instead of a full absolute URL starting with https://, the image server blocking automated or cross origin requests, or the image simply no longer existing at that URL. Check the tag table in the results to confirm the exact URL detected, then open that URL directly in a new browser tab to verify it loads correctly.
Open Graph tags are not a direct Google ranking factor, but they meaningfully influence how often your content gets shared and clicked on social media, since a compelling preview card increases click-through rate compared to a generic or broken looking link. More shares and clicks can indirectly support SEO through increased traffic, backlinks, and brand signals, even though the tags themselves aren’t read by Google’s ranking algorithm the way title tags are.
The page needs to be publicly reachable on the internet for this tool, or any social platform, to fetch and read its tags, password protected pages, localhost URLs, or staging environments behind a login won’t work. Most website builders and CMS platforms offer a staging or preview URL that’s publicly reachable but not linked anywhere, which works fine for testing purposes.
og:type tells the consuming platform what kind of content the page represents, common values include “website” for general pages, “article” for blog posts and news content, and “product” for e-commerce items. Some platforms use this to display additional structured metadata, like an article’s publish date or a product’s price, when the corresponding more specific Open Graph fields are also present.
No, this site does not log or store the URLs you check. The page fetch is routed through a public proxy service to bypass browser cross origin restrictions, and parsing happens entirely in your browser.
