SEO Facet EN

See every facet of a page's SEO, directly beside the page.

SEO Facet analyzes the rendered page you are viewing and presents its on-page SEO in a clean docked side panel or resizable overlay. No copy-pasting URLs, no View Source, and no account.

Open it from the toolbar, or use Ctrl+Shift+E (Cmd+Shift+E on macOS). Display settings let you choose the native dock or a remembered 360–800 px overlay width.

What you get

• A Preliminary or Verified SEO readiness indicator based only on universal readiness checks, with Errors and Warnings filters. Secondary diagnostics remain score-neutral.
• Current-visit Web Vitals for LCP, INP, CLS, FCP, and TTFB when the browser exposes them. These are local observations, not CrUX or PageSpeed field data.
• Meta tags, canonical and robots signals, Google SERP preview, and copyable values.
• JSON-LD schema blocks with required and recommended rich-result validation, plus a separate Breadcrumbs block for rendered HTML breadcrumb trails.
• H1–H6 counts and an outline, with exact click-to-locate navigation and heading-level highlighting.
• Image alt-text, decorative and oversized findings, dimensions, thumbnails, exact page location, and filter-based group highlighting.
• Internal, external, nofollow, unique, and missing-anchor link classifications, exact or destination-group highlighting, and an on-demand broken-link checker. Access-restricted responses are not mislabeled as broken.
• Facebook, X, and LinkedIn social previews.
• Sitemap Audit with nested-index discovery, current-page membership and source files, URL-set and lastmod coverage, and an optional bounded availability check for selected sitemap URLs.
• Crawl diagnostics ordered as Page readiness, Technical Audit, Mobile Diagnostics, and Accessibility Diagnostics, including redirect-aware status, response headers, X-Robots-Tag, robots.txt rules, and sitemap directives.
• Deep scan for lazy content, reversible page highlighting with Clear All, and CSV export.

Private by design. Page content and analysis results stay in your browser and are never sent to SEO Facet, analytics providers, advertisers, or data brokers. Only user-initiated Broken Link, Sitemap, and Technical Audit checks contact the relevant websites directly to report their status.

SEO Facet is a lightweight Manifest V3 extension with no remotely hosted executable code.
