As technical SEOs, we rely heavily on browser extensions to quickly audit web pages. But there was a problem: most SEO tools out there are bloated, require account sign-ups, or send DOM data to third-party servers to be processed.
At Kholaseh Agency, we believe in privacy, speed, and efficiency. That’s why our development team decided to build the Kholaseh E-E-A-T Radar—a 100% client-side, ultra-lightweight browser extension designed to analyze on-page trust signals instantly.
🚀 What Does It Do?
Instead of relying on external APIs, this extension uses pure Vanilla JavaScript to parse the active tab's DOM and extract crucial SEO entities:
- Content Depth: Accurately counts words and characters.
- Structure Analysis: Maps out H1, H2, and H3 tags to ensure logical hierarchy.
-
Link & Asset Auditing: Scans for internal/external links and images missing
altattributes. - E-E-A-T Signals: Evaluates schema markups and author trust signals directly from the page source.
🔒 Privacy-First Approach
The core philosophy behind this tool is security. The extension requests minimal permissions (activeTab and scripting) and performs all calculations directly within the user's browser. No data is collected, stored, or transmitted.
💻 Open Source & Available Now
We decided to open-source the core logic of the Kholaseh SEO Radar so other developers and digital marketers can learn, contribute, or adapt it for their own needs.
