What this tool does
When someone pastes your URL into Slack, X, LinkedIn, or iMessage, unfurls depend on Open Graph and Twitter Card tags. Broken previews look unprofessional and hurt click-through.
Why it matters
AI and humans both use shared cards as a first impression. Missing og:image or weak descriptions also weaken how pages are summarized elsewhere.
How it works
- We fetch your page and read title, description, og:image, favicon, and twitter:card.
- You see which fields are present vs missing.
- Email unlocks a concrete fix list.
Tips
- Use a 1200×630 image for OG.
- Keep titles under ~60 characters.
- Match og:title to the real page H1.
FAQ
Why does Slack still show an old image?
Many apps cache unfurls. Fix tags first, then re-share with a cache-busting query or wait for the cache to expire.
