Frequently asked questions
What does the OG image checker do?
It fetches the URL you paste, reads the Open Graph and Twitter Card meta tags exactly as a social crawler would, previews how the link unfurls on X/Twitter, LinkedIn, and Slack, and lists any missing or problematic tags.
Why doesn't my page show an image when shared?
The usual culprits: no og:image tag at all, a relative URL instead of an absolute https URL, an image behind authentication, a page that only injects meta tags with client-side JavaScript (most crawlers don't run JS), or a stale crawler cache — X and LinkedIn both cache aggressively.
What size should an og:image be?
1200×630 (1.91:1) is the safe standard across X, Facebook, LinkedIn, Slack, and Discord. Keep it under ~5MB and use PNG or JPEG.
How do I fix a missing OG image on every page of my site?
Generate them from your page titles instead of designing each one. ogsmith renders a designed 1200×630 card from a GET request — see the framework guides for Next.js, Astro, Hugo, Ghost, and Eleventy.
