Server-Side Tagging — Better Data, Faster Sites, More Control
Ad blockers, cookie restrictions, and browser privacy changes are degrading your analytics and conversion data. Server-side GTM moves tag processing to your infrastructure — improving accuracy, performance, and privacy compliance.
Safari's Intelligent Tracking Prevention wipes client-side cookies in as little as 24 hours — silently eroding attribution, session data, and conversion reporting for over a third of your traffic.
Safari and Firefox block third-party cookies entirely. Chrome is following. Every pixel, tag, and conversion tracker that relies on third-party cookies is already broken for a significant portion of your audience — server-side tagging is the fix.
ITP caps most client-side cookies at just 7 days — meaning most visitors never make it through a full attribution window before their tracking is wiped. Server-side cookies set under your own domain aren't subject to these restrictions, extending lifespan to 180+ days and keeping attribution intact across longer buying cycles.
