Take back control of the data your marketing runs on.

As privacy rules tighten and browsers and ad blockers limit cookies, traditional client-side tracking is losing data, and the campaigns that depend on it optimise on a false picture. Server-side tracking moves data collection from the browser to your server, so you keep more of it.

Using tools like the Meta Conversion API, our setups are especially effective for paid social and paid media, improving accuracy while staying compliant with GDPR. The result is reliable data feeding every platform, and better-performing campaigns.

What server-side tracking covers

Clean data flowThe layer underneath it all: accurate, consented data feeding every platform, because no campaign is better than its data.

Five shifts that make server-side tracking essential now.

Client-side tracking is fading, CAPI is becoming standard, and privacy and accuracy now have to coexist. Better data means better bidding.

01

Client-side tracking is fading

Cookie restrictions, ad blockers and browser privacy features mean client-side tags now miss a meaningful share of conversions.

02

CAPI is becoming table stakes

For Meta campaigns, the Conversion API is increasingly essential to capture conversions accurately and optimise spend.

03

Privacy and accuracy can coexist

Done properly, server-side tracking improves both: more control over user data and more accurate measurement at the same time.

04

Better data means better bidding

Platform algorithms optimise on the data you feed them. Cleaner, fuller data leads directly to better campaign performance.

05

One server, every platform

A single server-side setup can feed Meta, Google and the rest, giving you a consistent, unified view of customer interactions.

Our server-side tracking services, end to end.

What brands ask before they start.

What is server-side tracking?

A method of collecting user data through a server rather than client-side JavaScript. Data is sent from the user’s device to a server you control, which processes and forwards it to analytics and marketing platforms. It improves accuracy, reduces reliance on cookies and gives better control over privacy.

Why do I need server-side tracking?

It improves data accuracy by reducing the impact of ad blockers and browser restrictions, gives greater control over privacy and GDPR compliance, and can improve site performance by running fewer scripts in the browser.

How do I set up server-side tracking?

You choose a server environment, set up a server-side tag management container, deploy it to handle requests, establish a data layer, and send data via HTTP requests, then test and monitor it. It is complex and in-depth, so we recommend getting in touch, we can handle it end to end.

Is server-side tracking GDPR compliant?

It does not break GDPR in isolation, but implementation must be robust: explicit consent, transparency about data use, proper security and a process for users to exercise their rights. Done properly, it can enhance both compliance and user trust.

What is server-side event tracking?

Server-side tracking is the overall process of collecting and processing user data on a server. Server-side event tracking is a component of that, focused specifically on capturing individual interactions such as clicks, form submissions or page views.

Does it run scripts in the user’s browser?

No. Server-side tracking sends data directly from the device to a server via methods like HTTP requests and APIs, rather than executing client-side JavaScript, which gives more control over collection and improves privacy and accuracy.
