What is Open Graph Checker?
The Open Graph Checker fetches your page metadata and builds social preview cards. It highlights missing `og:` and `twitter:` tags and checks whether social images are likely to render correctly.
Why it matters: Social shares are a major traffic source. Broken or missing Open Graph tags mean your links show blank previews or wrong images, which kills click-through rates from Facebook, X, LinkedIn, and messaging apps.
Content Launch QA: Preview exactly how a blog post or landing page will look when shared on social before publishing.
Platform-Specific Debugging: Diagnose why LinkedIn shows the wrong thumbnail or why Discord displays a generic title instead of your custom og:title.
Campaign Validation: Check that campaign landing pages have correct og:image dimensions and compelling og:description copy before running paid social ads.

The recommended Open Graph image size is 1200 by 630 pixels for optimal cross-platform support. Use a clear subject and readable text that still looks good when cropped to smaller thumbnail sizes.
Shared links show stale previews because social platforms cache Open Graph metadata aggressively. After updating tags, use platform debug tools like the Facebook Sharing Debugger to force a cache refresh.
