Why this matters
A broken OG image is a silent conversion leak
Every share on LinkedIn, X, Facebook, or Slack either earns a click or gets scrolled past. A missing og:image, a cropped preview, or a tag pointing to a broken URL can tank your share CTR without you ever noticing.
Catch sizing issues before share day
Flags images below 600×315, off-ratio crops, oversized files, or formats that certain scrapers silently drop.
Audit Open Graph + Twitter together
Covers both og:* and twitter:* tags so previews render cleanly on Facebook, LinkedIn, X, Slack, Discord, and WhatsApp.
Ranked fixes, not a wall of warnings
Failed checks surface first with plain-language detail so you know exactly what to fix and in what order.
When to use it
Run the check before every public URL goes out
01
Pre-launch QA for landing pages
Before a product launch or paid campaign, confirm the share preview will actually look like the comp — not a 404 image or auto-scraped header logo.
02
Blog post publishing checklist
Run every new post through the checker so og:image, og:description, and Twitter card tags are locked in before the URL hits LinkedIn or X.
03
Fixing broken shares
When teammates report 'the link looks weird when I share it', this tells you which tag is missing or which image isn't resolving.
04
Paid social asset review
Media buyers can confirm the landing page share card matches the creative before ad links start running at scale.
Cheat sheet
Target specs the checker validates against
Dimensions
1200 × 630 px recommended. 600 × 315 minimum. Below that you get a small thumbnail instead of a full card.
Aspect ratio
1.91 : 1 (landscape). Off-ratio images get cropped on Facebook, LinkedIn, and Twitter summary_large_image cards.
File size & format
Under 8 MB (Facebook's hard limit). Ideal is under 1.5 MB. JPEG, PNG, or WebP for max scraper compatibility.
URL
Always absolute and HTTPS. Relative paths and mixed content get silently dropped by LinkedIn and some Slack integrations.
FAQ
Common questions about OG tags and social previews
It fetches your URL, parses every Open Graph and Twitter Card meta tag, then resolves and inspects your og:image — checking dimensions, aspect ratio, file size, format, and whether it's served over HTTPS as an absolute URL.
