What the checker looks for
A focused audit for the metadata that shapes link sharing and structured content.
Social metadata
Required Open Graph fields, X/Twitter fallbacks, descriptions, URLs, and conflicting declarations.
Share images
Image URLs, declared dimensions, large-card coverage, and verified Mosaicora CDN usage.
Parsed JSON-LD
Schema contexts, typed entities, graphs, key identity fields, and malformed structures.
Build a reliable social preview
Start with complete Open Graph tags
Provide a clear title, plain-text description, canonical page URL, content type, and an absolute image URL. A 1200 × 630 image is a practical cross-platform starting point.
Use JSON-LD for page meaning
Structured data should describe content users can actually see. This checker summarizes parsed entities, but schema-specific rich-result eligibility should be verified with Google’s Rich Results Test.
Focused scope
This is not a full technical SEO crawler. It does not currently verify title elements, canonical link elements, HTTP status, robots.txt, indexability, performance, or rendered page content.
Frequently asked questions
What does the Open Graph checker inspect?
It checks returned meta tags, Open Graph fields, X/Twitter card coverage, social images, duplicate declarations, and parsed JSON-LD.
Does this test every part of technical SEO?
No. It does not currently verify HTTP status, robots.txt, canonical link elements, page performance, rendered content, or rich-result eligibility.
Why can a social preview differ after I fix my tags?
Social platforms cache link data and apply their own cropping rules. You may need to use each platform's refresh tool after publishing changes.
Are checked URLs and results saved?
No. Results are returned for the current browser session. The URL may appear in the page query string so you can rerun the check.
