Server-Side Tagging

Move tags to the server.

What Server-Side Tagging Is

Server-side tagging moves your tag execution out of the user's browser and into a server you control. Instead of the page firing pixels directly to Google and Meta, it sends one request to your own tagging endpoint.

That server then decides what to forward, to whom, and in what shape. The browser only ever talks to your first-party domain.

Client vs Server Flow

In the classic model, every vendor pixel runs in the browser, each making its own third-party request. In server-side, the browser sends one event to a tagging server, which fans it out.

This gives you control over data, reduces blocked requests, and shrinks the client-side code footprint that slows pages down.

CLIENT-SIDE (old)
  Browser --> google-analytics.com
  Browser --> facebook.com/tr
  Browser --> tiktok.com/pixel
   (each blockable, leaks data)

SERVER-SIDE (new)
  Browser --> sgtm.yoursite.com  (1 request)
                   |
        +----------+----------+
        v          v          v
      GA4        Meta CAPI   TikTok
   (server-to-server, controlled)
