Open Graph Checker
The Open Graph Checker is a diagnostic tool used to audit and verify that your website's Open Graph (OG) meta tags are correctly implemented. While a generator creates the code, the checker acts as a quality assurance specialist, ensuring that when your links are shared, they actually display the images and text you intended.
In 2026, where social media algorithms are highly sensitive to "rich" content quality, a broken preview can decrease your click-through rate (CTR) by up to 40%.
Why You Must Use a Checker Before Posting
Even if you have added OG tags, several technical issues can still "break" your social preview:
-
Caching Issues: Platforms like Facebook and LinkedIn "remember" old versions of your page. If you update an image, the checker helps you force the platform to see the new one.
-
Image Dimension Errors: If your image is too small (below $200 \times 200$ pixels), the platform may ignore it entirely and pull a random image from your sidebar instead.
-
Malformed Code: A single missing quote or a tag placed outside the
<head>section of your HTML will render the tags invisible to social crawlers. -
Redirect Loops: If your URL redirects multiple times, crawlers might give up before finding your metadata.
Top Issues Detected by an OG Checker
-
Missing Required Tags: Every page must have
og:title,og:type,og:image, andog:url. A checker will highlight if any of these are missing. -
HTTPS Mismatches: If your site is secure (HTTPS) but your image URL is standard (HTTP), many platforms will block the image for security reasons.
-
Incomplete Metadata: Some platforms require specific additions, like
fb:app_idfor Facebook analytics ortwitter:cardfor X. -
Text Truncation: If your
og:titleis too long (over 60–90 characters), the checker will show you where the text gets "cut off" on mobile devices.
Step-by-Step: How to Audit Your URL
-
Input URL: Enter the link you plan to share into the RankLogic checker.
-
Analyze the Results: The tool will provide a simulated preview of how the post will look on Facebook, LinkedIn, and X.
-
Check for Warnings: Look for red text or warning icons indicating missing tags or incorrectly sized images.
-
Force a Refresh (Re-Scrape): If the checker shows an old image, use the official "Debugger" links (Facebook Sharing Debugger or LinkedIn Post Inspector) provided in the tool to clear the platform's cache.
