What this viewer checks

Inspect public page metadata or pasted HTML for search, social, and document-structure signals.

  • Title, description, canonical, robots, language, and viewport
  • Open Graph and X/Twitter card fields
  • H1 count, hreflang links, and JSON-LD block count

Use results as a diagnostic

A missing field is a prompt to review the page, not proof that a page cannot rank or share well. Confirm final output in the browser and with each platform’s own tools.

Methodology

  • Extracts common HTML metadata from the supplied document source.
  • Flags absent required basics and common length guidance; it does not score rankings.
  • Previews are illustrative only and do not replicate Google, Facebook, or X rendering exactly.

Limitations

  • JavaScript-injected tags may not be present in the initial HTML response.
  • Search engines and social networks can cache, rewrite, ignore, or augment metadata.
  • This is not a crawl, indexability, ranking, or accessibility audit.

Privacy

Pasted HTML stays in your browser. For URL analysis, the service retrieves only a public HTML response; do not submit pages requiring credentials.

FAQ

Plain answers about what this tool does and does not claim.

Will Google show this exact title? +
Not necessarily. Google may rewrite title links based on the query, page content, and other signals.
Does this fetch private pages? +
No. URL analysis accepts only public HTTP(S) URLs and blocks local/private network addresses.
Are pasted pages stored? +
No. Pasted HTML is analyzed in your browser. URL analysis temporarily retrieves the public response to return it to your browser.
