About
Server-Side Tagging Detector Easily detect server-side Google Tag Manager implementations on any website! This Chrome extension helps digital marketers, analysts, and developers quickly determine whether a website uses server-side Google Tag Manager (GTM) for analytics and tracking. It inspects network requests and cookies to detect server-side tagging configurations in real-time. What It Does: Identify Server-Side GTM: Analyzes GTM request URLs to detect if the tagging is hosted on a custom server instead of Google’s standard infrastructure. FPID Cookie Check: Scans for FPID cookies and determines whether they are marked as HttpOnly, a common indicator of server-side tagging. Visual Feedback: Provides instant results via a toolbar badge (green for server-side GTM, red for standard GTM). Detailed Console Output: Logs clear and detailed results, including URLs and hostname information, directly to the browser's developer console. Why You Need It: Save Time: Quickly verify tagging setups without manually inspecting network requests or cookies. Improve Analytics Strategies: Ensure accurate data collection and identify opportunities for server-side tracking optimization. Essential for Marketers and Developers: Perfect for those managing analytics configurations, ensuring data privacy compliance, or optimizing server-side implementations. Install now to streamline your analytics debugging and enhance your tracking setup evaluation!
