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
