On-page SEO analysis and technical SEO auditing for any visited webpage

Helps web developers, SEO professionals, and site owners quickly analyze on-page SEO factors of any webpage without leaving the browser, identifying issues and optimization opportunities across 100+ parameters

User clicks the extension icon on any webpage → extension popup opens → analyzes the current page's SEO attributes via content scripts and sitechecker.pro API → displays comprehensive on-page SEO report with issue highlights, recommendations, and on-page element highlighting. GSC+GA4 features require Google account login via OAuth.

Target users: SEO professionals / Web developers / Digital marketers / Content creators / Site owners

Large minified JS files (704KB main, 156KB background) make detailed code analysis difficult
Cannot definitively determine if basic SEO analysis requires login or only GSC+GA4 features do
Cannot confirm if the extension itself gates paid features or if limitations come from the destination service's API tier system

Reason: The manifest declares the 'identity' permission and background.js contains a Google OAuth client ID ('1022584819233-669scs01e2804qlf755ebej75ccjaokv.apps.googleusercontent.com') connected to sitechecker.pro. The extension also contains logout icon SVG and 'unlock_ga'/'unlock_gsc' JPG assets suggesting GSC+GA4 features require account login. The store description mentions GSC+GA4 Insights features that inherently require a connected Google account.
