Answer first

What it checks

The scan inspects title tags, meta descriptions, canonical links, og:title, og:description, og:image, Twitter Card tags, and image reachability.

Detail 01

Launch-specific issues

Missing images, staging canonicals, relative image URLs, blocked preview assets, and duplicate descriptions are the most common failures.

Detail 02

What to ship

Use absolute production URLs, a 1200 by 630 preview image, route-specific copy, and the same canonical URL everywhere.

FAQ

Common questions

What size should og:image use?
1200 by 630 pixels is the safest default for large preview cards across common social and messaging surfaces.
Is Open Graph an SEO ranking factor?
Open Graph mainly controls sharing previews, but clean metadata also makes public pages easier for crawlers and AI systems to classify.
