Open Graph Preview Checker – Test Social Media Link Previews
About the Open Graph Preview Checker
The Open Graph Preview Checker fetches a URL and shows exactly how it will appear when shared on Facebook, Twitter, and LinkedIn, alongside a full table of the extracted Open Graph and Twitter Card meta tags. If a tag like og:image or og:description is missing, it falls back to the page title, meta description, or first image, and flags what wasn’t found.
It’s built for marketers and developers confirming that a page looks right before it’s shared, especially after updating a site’s metadata. Once you’ve spotted missing tags, the Schema Markup Generator can help you add structured data alongside your Open Graph tags, and the Sitemap Generator is useful for making sure the same pages are properly indexed.
Our team tested this checker against pages with complete Open Graph tags, pages missing them entirely, and relative image URLs to confirm the previews and fallback logic render accurately across all three platforms.
How to Use the Open Graph Preview Checker
- Enter the full Website URL you want to check, including
https://. - Click Check Preview to fetch the page.
- Review the Facebook, Twitter, and LinkedIn preview cards side by side.
- Scroll down to the Extracted Meta Tags table to see every Open Graph and Twitter Card value found.
- Look for any tags marked Not found and add them to your page.
Example Usage
Input: https://example.com/blog/new-feature
Output: A Facebook-style card showing the page’s og:image, og:title, and og:description, plus a table confirming which of the eight standard Open Graph and Twitter Card tags are present.
If the check comes back with several tags missing, that usually means the page is relying entirely on fallback values like the plain page title, which can make link previews look inconsistent across platforms. Running the same URL through the Redirect Chain Checker is also worth doing if the preview looks wrong, since redirects can sometimes point crawlers to an unexpected final page.
Frequently Asked Questions
The tool falls back to the page’s title tag, standard meta description, and first image found on the page, so you still get a usable preview even without dedicated Open Graph markup.
Twitter Cards typically use a different aspect ratio than Facebook’s Open Graph image, so the preview height is adjusted to reflect how it would actually appear on that platform.
No, it fetches the page fresh each time you run a check, so it reflects your current meta tags rather than a cached version a platform might be showing.
This can happen if the og:image tag is missing, points to a broken URL, or uses a relative path that couldn’t be resolved to a full URL.
Yes, it’s completely free with no signup required.
