google-analytics-proxy

Some users use ad blockers (or other network filters) which will block Google Analytics scripts and requests. Inaccurate data is bad. This repository offers a tiny Nginx proxy for Google Analytics and Google Tag Manager to get metrics for people with blockers.

The proxy carefully forwards the client real IP address to Analytics using the Google Analytics Measurement Protocol URL parameter. So you don't have to worry seeing the proxy's IP instead of client's in GA.

Usage

1. Have a look at Dockerfile and nginx.conf. Basically you will only need to override GAPROXY_HOST environment variable to get the proxy work.
2. If this proxy is placed behind another reverse proxy, add X-Real-IP header in the front reverse proxy so google-analytics-proxy can forward the real client IP to Google Analytics.
3. Replace gtag.js, analytics.js, gtm.js, ns.html with the one under your proxy domain.
