SPA: SEO Page Audit nga Ivan Lukichev

SPA: SEO Page Audit gives you a local page-level SEO audit workflow inside Firefox.

The extension analyzes the current page in the browser, uses browser-detectable signals from the live DOM, and avoids third-party SEO APIs or remote scoring services.

Main features:
- Popup mode for quick summary
- Full page mode for detailed audit
- On-Page SEO score with section breakdowns
- Headings, links, images, schema, and social checks
- Accessible anchor name detection across text links, aria labels, and image alt text
- Human-readable issues and quick wins

What it does not do:
- It is not an official Google score
- It does not estimate rankings
- It does not use backlink or traffic data providers
