Server-side tracking · GTM + sGTM

Server-side tracking that actually measures your conversions.

Ad blockers, Safari and expired cookies leave gaps in your data. We set up server-side tracking on a subdomain of your own website, with first-party cookies, Meta CAPI, Enhanced Conversions and consent mode. So Google and Meta optimize on data you can rely on.

How it works

3 steps to tracking that misses nothing

Not just a tool, but a team. The same marketing experts who run your campaigns set up your tracking and keep it sharp.

  1. Step 01

    Audit and migrate

    At the start, we check whether you already use GTM or sGTM and move you over to our own server-side environment. Whatever already works well, we reuse.

  2. Step 02

    Server and connections

    You get a server-side container on a subdomain of your own website. Then we connect Google Ads, GA4, Meta CAPI and your other platforms.

  3. Step 03

    Validate and monitor

    We test every data stream and compare it with your existing measurement. After that, we monitor your tracking server continuously, so you know when something falters.

Without vs with server-side

Conversions you miss today come through again

With browser-only tracking, your tags load from Google and Meta. Ad blockers stop them, Safari expires cookies faster and some of your conversions never arrive. Through your own subdomain, that data does come through.

First-party cookies on your domain

Cookies are set from your own domain. They last longer and returning visitors are recognized again, on Safari and Firefox too.

Less affected by ad blockers and ITP

Your events run through your subdomain instead of third-party scripts. So far less data gets lost.

Consent mode

More data, with respect for consent

Server-side tracking is not a trick to get around cookie consent. The server only forwards what your visitor has agreed to. You decide which data goes to which platform.

  • Consent mode set up, defaulting to 'denied' until the visitor chooses
  • Consent checks enforced on the server
  • Personal data hashed or removed before it's sent on
  • IP addresses can be anonymized, set up GDPR-compliant

One server, every platform

Every platform gets the data it needs

Meta gets your conversions via the server too

Alongside the Pixel, every event also goes server-to-server to the Meta Conversions API. Duplicate events are deduplicated via an event ID, and hashed data makes for better matching.

With server-side tracking, your website’s events don’t go straight from the browser to Google, Meta and other platforms. They first go to a server-side Google Tag Manager (sGTM) on a subdomain of your own website. That server processes and enriches the data and then forwards it. This gives you more control, a better handle on privacy and more accurate conversion data.

Browsers like Safari (ITP) and Firefox (ETP) restrict cookies and shorten their lifespan, so returning visitors are no longer recognized. Ad blockers often block Google and Meta tracking scripts entirely. The result: some of your conversions never reach your ad platforms, which then optimize on an incomplete picture. With server-side tracking, cookies are set from your own domain and events go through your subdomain, which is far more reliable.

No. Server-side tracking is not a way to get around consent. We set up consent mode so that nothing is stored by default until the visitor makes a choice. If someone doesn’t give consent, no ad cookies are set and no personal data is passed on. The server only forwards what consent has been given for.

Server-side tracking actually gives you more control over privacy. You decide which data goes to which platform. Personal data can be removed or hashed before it’s sent on, IP addresses can be anonymized and consent checks are enforced on the server. It’s a step towards better privacy, not less.

At the start, we check whether you already use GTM or sGTM and move you over to our own server-side environment. We reuse existing tags, triggers and variables wherever we can, instead of rebuilding everything. That way your existing measurement stays intact and we build on it.

Once an event reaches your server, it goes to every platform you use: Google Ads with Enhanced Conversions, Google Analytics 4, Meta via the Conversions API (CAPI) and more. One server-side setup feeds all your channels.

Google Ads and Meta adjust their bids based on the conversions they get to see. The more complete and reliable that data, the better they can optimize. That’s why we combine server-side tracking with our campaign management: our AI and marketing experts then work with data you can rely on.

That depends on your website, your traffic and the platforms you use. In a demo, we look at your current tracking together and tell you what’s needed. Rather take a look yourself first? Start with a free audit of your Google Ads or Meta account.
