Services / Data & Automation / Server-Side Tracking
Tracking that survives iOS 17, cookie banners and ad blockers.
30–50% of your conversions disappear in the standard client-side setup. Server-side tracking makes them visible again — GDPR-compliant, without dark patterns. I deliver a setup hand, not a tool sale.
GDPR-compliant
EU hosting, hashed first-party data, consent-mode integration. No Cloud Act risk, no dark patterns.
Conversions back
30–50% recovery through CAPI + Enhanced Conversions + Events API. The algorithms learn again, scaling becomes possible.
The data is yours
Your own server container, no proprietary tool between you and the platforms. Switchable, exportable.
What you can book
Six building blocks, individually or as a package
We usually start with audit + container setup. Platform integrations only come once the architecture is in place.
Tracking audit
Pixel health, event map, consent-mode status, conversion gaps between GA4 and Ads. Output: triage report.
Server container setup
Stape or custom GCP, custom domain, cookie mapping, first-party subdomain (data.yourdomain.com).
Meta CAPI + TikTok Events
Server-side conversion API, deduplication, hashed user data. For iOS- and cookie-banner-resistant optimization.
GA4 + Enhanced Conversions
Clean event modelling, Measurement Protocol, server-to-server connection to Google Ads.
Consent integration
Cookiebot/Usercentrics/Klaro with Google Consent Mode v2, correct default states, documented DPA.
Monitoring + validation
Tag Assistant, Looker Studio health dashboard, alerting on drops, monthly sample validation.
How do we differ?
Three ways to buy server-side tracking
SaaS tool, enterprise hub or senior operator — depth and the work left on your plate differ greatly. Here's the honest comparison.
| SaaS tool Tracify, Cometly, Stape | Enterprise data hub Mediaplus, FELD M | Truong Suarez Setup hand + ownership | |
|---|---|---|---|
| Model | SaaS subscription €99–1,000+/month | Retainer €10–30k+/month | Fixed-price audit + setup project, then upkeep optional |
| Data ownership | In the tool's DB, lock-in risk | Agency setup, often proprietary | Your own GTM container, your own subdomain, your Vercel/GCP |
| GDPR depth | Variable (some EU-only, some US data) | Very strong, DPA/SCC documentation | EU-only setup as standard, with documentation |
| Tool flexibility | Limited to the tool's features | Custom setup possible | Stack-agnostic: Stape, custom GCP, Cloudflare Workers |
| Best phase | DTC e-commerce without dev resources | Enterprise with multi-brand complexity | Mid-market with a performance stack that wants ownership |
Comparison based on publicly available information, as of 2026. If your situation would be better served elsewhere, I'll tell you so in the intro call.
How we work
Five phases, one point of contact
Audit as the baseline, then a structured setup. No tag-and-pray implementation.
Audit
Pixel health, event map, conversion gaps, consent status. Output: triage report.
Container
Server container, subdomain, cookie mapping. Output: live container.
Platform integration
GA4, Meta CAPI, TikTok Events, Enhanced Conversions. Output: all platforms receiving data.
Validation
Deduplication, match-rate test, cross-platform comparison. Output: validated state.
Monitoring
Health dashboard, alerting, monthly samples. Output: live status.

Recommended entry point
Two paths, depending on where you stand
For existing tracking setups, a tracking audit is enough. For full server-side migrations, the Growth Sprint is the better choice.
For you if
Tracking is already running but leaking
You have GA4, the pixel and CAPI in pieces. You want to know where the system leaks and which quick wins pay off most.
5–7 days · report + 30-min call
Starter Audit / Tracking
- – Pixel & event health check
- – Conversion delta (GA4 vs. Ads vs. shop)
- – Consent-mode status
- – Top 3 quick wins for recovery
For you if
A full new setup or a migration
You're starting from scratch or migrating to server-side. You need architecture, container choice and a platform integration plan.
2 weeks · report + workshop
Growth Sprint
- – Architecture concept (container, subdomain)
- – Platform integration plan
- – Consent strategy + documentation
- – Migration roadmap with effort estimate
- – Half-day workshop

When this becomes relevant
Typical starting points
Three recurring situations where server-side tracking is the right tool.
Recovery
Tracking despite consent loss
How 30–50% of lost conversions come back — GDPR-compliant, without dark patterns.
Multi-channel
Multi-channel sales data
When every channel claims the conversion for itself — how server-side creates clarity.
Compliance
GDPR-compliant consent setup
Consent Mode v2 with correct default states and documented DPA — clean instead of risky.
FAQ
What clients often ask before the first collaboration
Do I really need server-side tracking?
If your monthly ad budget is below €3k, probably not — the effort doesn't pay off. Above €5–10k/month: yes, because 30–50% recovery shows up directly in ROAS. For e-commerce scaling on Meta it's practically mandatory.
Stape, Tracify or custom GCP?
Stape: the best choice for 90% of clients — cheap (from $20/month), EU hosting, fast setup. Tracify: when AI attribution and incrementality testing are core requirements (DTC e-commerce). Custom GCP/Cloudflare: enterprise with its own compliance requirements or special performance needs.
How long does a server-side setup take?
For a typical e-commerce setup with GA4 + Meta + TikTok: 3–4 weeks end to end. Audit 1 week, container setup 1 week, platform integration 1–2 weeks, validation 1 week. For more complex setups (LinkedIn, Pinterest, custom events) add 1–2 weeks accordingly.
Is this really GDPR-compliant?
Yes, when done right: EU hosting (Stape EU or GCP Frankfurt), Consent Mode v2 with correct default states, hashing of personal data before sending to US platforms, documented DPA. I deliver the GDPR documentation as part of the setup, your data protection officer reviews it.
What does it cost on an ongoing basis?
Tool costs: Stape from $20/month, a GCP setup $50–150/month depending on traffic. Upkeep: once everything runs, 2–4 hours/month for monitoring. I offer upkeep as an optional retainer or hand it over to your team — both work.
