FREE LAUNCH CHECK GUIDE
Open Graph and Twitter Card Checker
Check the title, description, image, Twitter card, and favicon that social platforms read from your homepage, then fix preview-domain and missing-image issues.
Run this check on my homepage →What this check catches
A strong page can look unfinished when its shared link has no image, stale copy, or a preview-domain identity. Social bots usually read server-delivered metadata rather than interpreting the visual page like a person.
Why it matters before launch
Broken previews reduce clarity and trust at the moment someone shares a launch. They can also preserve an old name or domain long after the visible page has changed.
Common warning signs
- og:title or og:description is missing
- og:image is relative, unreachable, or the wrong size
- twitter:card is absent
- The preview copy or image still names a staging domain
How to inspect it
- Inspect Open Graph and Twitter metadata in the served head
- Open the absolute image URL without authentication
- Confirm the image and copy match the live product and domain
- Use a platform preview debugger to refresh cached cards
How to fix it
- Add accurate og:title, og:description, and an absolute og:image
- Set twitter:card to summary_large_image when the asset fits
- Use a 1200 × 630 image with readable text and brand contrast
- Update metadata and image copy whenever the public domain or positioning changes
Verify after the change
Deploy, inspect the raw tags, open the image URL, and refresh platform caches. Run a new LaunchCheck scan to confirm all fields are present.
