Everything it checks.

Sixteen on-page signals graded pass, warn, or fail — the same fundamentals search engines read first, shown as a colour-coded report the moment you click.

Title & meta

Presence and length of the title and meta description, flagged against best-practice ranges (30–60 and 70–160 characters).

Headings

Confirms exactly one H1 and builds a heading outline (1×H1 · 3×H2 …) that catches skipped levels.

Indexability

noindex detection, canonical (self-referencing, missing, or points elsewhere), and whether the page is served over HTTPS.

Structure

Checks the <html lang> attribute and a mobile viewport meta so the page reads as mobile-ready.

Social cards

Open Graph completeness (title, description, image) and whether a Twitter card is set for rich link previews.

Structured data

Lists detected schema.org types and hreflang locales, including whether an x-default alternate is declared.

Content & links

Word count with a thin-content warning, images missing alt text, and internal / external / nofollow link counts.

Favicon audit

Your favicon, everywhere it shows up.

Most sites get their favicon half-right. See your icon exactly as it appears in a browser tab, Google mobile results, and an iOS home-screen tile — plus a checklist of what a complete setup needs, with a one-line fix for each gap.

  • Browser-tab iconA reachable favicon for the tab
  • SVG iconA modern, crisp vector icon
  • Apple touch icon180×180 for the iOS home screen
  • Manifest icons192 + 512 + maskable for Android / PWA
  • Google-search faviconSquare, reachable, ≥48px multiple
  • Theme colorThe address-bar tint on mobile

Nothing leaves your browser

The report is generated locally and discarded when you close the popup. No page content, URL, or result is ever transmitted.

Minimal permissions

Only activeTab and scripting — it reads a page just at the moment you click, with no access to other tabs or background browsing.

No login, no lock-in

Questions? We have answers.

Is it really free?

Yes. The On-Page Checker is completely free, with no account, sign-in, or trial. Install it and start grading pages immediately.

Does it send my browsing data anywhere?

No. Everything runs locally in your browser. The extension only reads a page when you click its icon (activeTab), requests no broad host permissions, and sends nothing to VibeSEO or any third party.

Which pages does it work on?

Any http(s) page you can open in Chrome — your own site, a client’s, or a competitor’s. It grades whatever page is in the active tab the moment you click.

What is the favicon audit?

It shows your icon exactly as it appears in a browser tab, Google mobile results, and an iOS home-screen tile, then checks favicon.ico, an SVG icon, apple-touch-icon, web-manifest icons, the Google-search favicon requirement, and theme color — with a one-line fix for each gap.

How is this different from the VibeSEO app?

The extension is a fast, private spot-check for a single page. The full VibeSEO platform adds keyword research, site audits, backlinks, Search Console, and AI content that writes and publishes to your blog — start free at vibeseo.dev.
