SEO All Autor: StaticUX

Eliminate manual testing and QA friction entirely. We built SEO All to give developers and SEO specialists a flawless, zero-click auditor inside the Firefox sidebar.

Instead of jumping between tabs or running heavy external scans, the extension works actively in the background. It monitors, parses, and analyzes your web assets automatically as you browse.

Core Features Provided:
• Real-Time W3C HTML Validation: Checks markup syntax errors and warnings automatically.
• Core Web Vitals Tracking: Measures CLS and LCP scores with built-in threshold validation.
• Link & Backlink Audit: Identifies invalid layout targets, broken destinations, and insecure target rules.
• Metadata & Google SEO Controls: Tracks page title and description lengths against search engine targets.
• Technical Diagnostics: Verifies canonical alignment, indexation blockades (noindex alarms), and structured Schema profiles.
• Hreflang Mapping: Extracts international geo-targeting link signals instantly.
