Required OG fields
The Open Graph protocol expects title, type, image, and URL. Description, locale, site name, image dimensions, and image alt text improve clarity and accessibility.

Build and check social preview metadata
Create Open Graph and X card tags, or paste existing head markup to find missing required fields, duplicate declarations, invalid URLs, image alt gaps, and unresolved template tokens before a page is shared.

Evidence boundary: OpenWebmaster builds and checks Open Graph and X card metadata from supplied fields or pasted source. It does not prove that Facebook, LinkedIn, X, Slack, iMessage, or another platform crawled, cached, rendered, resized, accepted, or displayed the preview, and it does not estimate rankings, traffic, engagement, conversions, or cause.
OG
Ready for social metadata.
No sample card score, guaranteed Facebook preview, guaranteed X preview, engagement estimate, ranking claim, traffic claim, or manufactured platform result appears before you provide fields or source.
Practical social-card QA without platform theater
X card coverage
X card tags are checked separately, including card layout, title, description, image, site handle, and image alt text.
Platform verification
After deployment, use platform debuggers and the live OpenWebmaster URL tools to verify the final response. This checker cannot clear or predict third-party caches.
