Server-Side Tracking That Survives Browser Restrictions

No, and any agency telling you it does is selling you a compliance problem. Server-side tagging changes where data is processed, not whether you need permission to process it. We build every container with Consent Mode v2 wired in, so denied consent means signals only — never identifiable data.

Hosting is usage-based. On Google Cloud Run, cost scales with request volume and container instances. We forecast your monthly spend during the architecture phase using your actual traffic, and configure autoscaling ceilings so it cannot run away. You approve the number before we deploy.

No. We run the server container in parallel with your current client-side setup, reconcile the two, and only cut over once numbers agree. Nothing is switched off until the replacement is proven.

Yes. We deploy server containers on your own VPS or private cloud using Docker for clients who need data to stay within specific infrastructure. We size the instance and configure monitoring as part of the build.

Most server-side builds run three to five weeks end to end. The container deployment itself takes days; the time goes into the dataLayer work and the validation phase, where we reconcile server-side events against your order table until the numbers agree. Complex multi-market setups take longer, and we tell you which category you are in after the audit rather than quoting a timeline before we have seen your stack.

Implementation typically starts around €1,500 for a single-market setup and scales with the number of storefronts, destinations, and the state of your existing dataLayer. Separately, hosting the container costs a usage-based monthly amount that we forecast from your actual traffic before deployment. We give you both numbers in writing after the audit, and you approve them before any work starts.

Often not, and we will say so. The work has a fixed cost regardless of your revenue, so the return depends on how much data you are actually losing and what that data is worth. Below roughly €25,000 per month in online revenue, the payback period usually stretches past a year. Above it, recovered attribution tends to cover the build within a quarter. The audit gives you the number for your situation.

A plugin fires tags from the visitor's browser, so it inherits every browser restriction — ITP cookie limits, ad blockers, consent denials. Server-side tracking moves collection onto infrastructure you control, sets cookies via HTTP headers instead of JavaScript, and forwards enriched events to each destination from your own endpoint. They solve different problems. A plugin is configuration; this is data architecture.

Yes, and if you have an in-house developer comfortable with GTM and cloud infrastructure, that is a reasonable path — the documentation is public and the tooling is not exotic. Where teams typically get caught is deduplication, identity persistence, and consent forwarding, which fail silently and look correct in the interface. If you want to try it in-house, the audit will still tell you what is currently broken.

It usually makes it faster. Moving tag execution off the browser removes third-party JavaScript from the main thread, which is often the largest contributor to poor interaction responsiveness on e-commerce sites. The server container adds latency to the data pipeline, not to page rendering. Your visitors do not wait for it.
