Open Graph Checker: Test OG Tags, Images & Previews

Run a live Open Graph test for any URL. Inspect the tags and share image, preview the resulting cards, trace redirects, and copy the exact fixes your page needs.

What the Open Graph Checker Tests

Open Graph Readiness Score

Separate passes, warnings, and failures with specific fixes.

Raw OG & Twitter Tag Inspector

Verify the exact Open Graph, Twitter, robots, and canonical values found.

OG Image Validation

Check whether the image responds publicly, its format, byte size, and dimensions.

Shareable Metadata Report

Copy, share, or download the live report for a developer, client, or release checklist.

Need a platform-specific workflow? Use the Twitter Card validator, LinkedIn post preview, or Facebook Open Graph debugger.

Copy for an AI agent

Generate a self-contained repair prompt with the failed checks, current tags, suggested code, and verification requirements.

Compare before and after

Diff a production URL against staging or a replacement page before you ship metadata changes.

Compare two URLs →

Keep a live report URL

Share a re-runnable report link. It fetches the page again so collaborators see the latest deployed metadata.

How to Run an Open Graph Test

  1. 1. Enter the final public URL.

    The checker follows and records redirects, fetches the HTML, and inspects the declared share image.

  2. 2. Review previews and failures.

    Confirm the visible title, description, and crop, then work through warnings in the diagnostic report.

  3. 3. Copy a fix and retest.

    Paste the suggested code or AI-agent prompt into your workflow, deploy, and rerun the same URL to verify it.

Minimum Open Graph Tags

A reliable link preview starts with one clear value for each core property. Use absolute HTTPS URLs for the page and image.

<meta property="og:title" content="A clear, specific title" />
<meta property="og:description" content="A concise reason to open this page." />
<meta property="og:image" content="https://example.com/social-card.jpg" />
<meta property="og:url" content="https://example.com/page" />
<meta property="og:type" content="website" />
<meta name="twitter:card" content="summary_large_image" />

Fix the Most Common Open Graph Problems

Open Graph image not showing

Debug missing, blocked, relative, or incorrectly sized share images.

Twitter/X Card preview not showing

Fix card type, image, fallback, crawler, and cache problems.

LinkedIn preview not updating

Separate live metadata problems from LinkedIn cache problems.

Facebook link preview wrong

Correct stale titles, images, descriptions, and canonical mismatches.

Open Graph image sizes by platform

Choose a safe aspect ratio, dimensions, format, and file size.
