Real Open Graph Checker example: before vs. after

A blog post that was being shared on LinkedIn with a broken, generic-looking card because og:image was missing.

Before · Before

4/5

Tags passing

Missing og:image meant shares showed no preview image at all, hurting click-through on social.

After · After adding the tag

5/5

Tags passing

Every share now renders a real preview card with image, title, and description.

Frequently Asked Questions

Why does my share preview look different on different platforms?
Each platform (Facebook, LinkedIn, Slack, Discord) caches Open Graph data separately and may crop images differently. Getting all 5 core tags right gives every platform what it needs, but exact rendering still varies.
Do I need Twitter Card tags too?
Most platforms that check for twitter:card fall back to your Open Graph tags if it's missing, so it's optional but recommended for the best result specifically on X/Twitter.
Why is my preview showing an old image?
Facebook and LinkedIn cache share previews aggressively. Use Facebook's Sharing Debugger or LinkedIn's Post Inspector to force a re-scrape after updating your tags.
What size should my og:image be?
1200x630px is the widely recommended safe size that renders correctly across Facebook, LinkedIn, and Slack without awkward cropping.
