Page Info Tab

Purpose

The tab is split into sections you can jump between: General Info, Headings, Hreflangs, Robots, and Sitemap.

Title and meta description with character counts and colour-coded length warnings.
URL, canonical, and an indexability verdict. Canonical is labelled self-referencing, canonicalized, or missing.
Robots directives from all three places they can hide: the meta tag, the x-robots-tag header, and robots.txt. Each is copyable, and there is a direct link to the live robots.txt.
A.I. Bots check. Tests robots.txt against 14 named AI crawlers, including GPTBot, ClaudeBot, PerplexityBot and Google-Extended, and shows which are blocked with a running count. This is the fastest way to answer “are we visible to AI search at all”.
Core Web Vitals from CrUX field data (LCP, INP, CLS), falling back to the origin summary when there is no page-level data.
Word count and a full heading inventory, H1 to H6, with counts and the heading list.
Hreflang table, including a back-reference check that flags alternates which do not point back at this page.
Sitemap detection with the sitemap URLs found, and a schema presence notice.

Single-screen triage: indexability, metadata, content length, and vitals without opening DevTools.
Heading inventory shows structure issues before you run full audits.
Robots + canonical badges clarify conflicts fast.

Indexability sanity: Check robots meta/x-robots + canonical together.
Content snapshot: Word count + H1/H2 counts to spot thin pages.
Internationalization: Hreflang/sitemap presence to confirm alternates published.

Canonical vs. indexability: a canonical to non-indexable target may still block.
Empty data can come from redirects, blocked requests, or restricted pages.
If the page changed, reload and reopen the popup to refresh data.
