Tracking Server-Side & Conformité nLPD en Suisse - Le Guide Complet 2026
Questions fréquemment posées
What is "Server-Side" tracking?
▾
It is a method where the browser sends data to your intermediary server (proxy), which cleans it and then forwards it to the platforms. You maintain full control of the data before it goes to the GAFAM.
What are the major advantages of Server-Side?
▾
Bypassing AdBlockers.
Extension of cookie lifespan (bypassing Safari ITP).
Data protection (anonymization before sending).
Improvement of site loading speed (fewer scripts in the browser).

Does Server-Side allow tracking everything, even without consent?
▾
Technically yes, but legally no. You must respect the user's choice in the cookie banner, even if you have the technical ability to bypass it. Server-Side is for data quality, not for violating the law.
Is it complicated to migrate to Server-Side?
▾
It requires sharp technical expertise (DNS management, GTM configuration, API). This is the core business of agencies like A-Track. A poor configuration can lead to a total loss of data.
Can I use GTM Server-Side for tools other than Google?
▾
Yes. You can send data to Facebook, TikTok, Pinterest, LinkedIn, Klaviyo, or even your own SQL/BigQuery database from the same server.
What is the monthly cost of a Server-Side infrastructure?
▾
With Stape, it starts around 20-30 CHF/month for a standard site, compared to often over 100-150 CHF/month on Google Cloud for equivalent performance.
How long does Server-Side compliance and installation take?
▾
For a standard site, it takes between 3 to 7 business days for the audit, configuration, testing phase, and going live.
Does Server-Side Tracking expose my server to security vulnerabilities?
▾
No, if it is properly configured. The GTM Server-Side container operates in an isolated environment (Docker/Sandboxed). It does not have direct access to your client database or back-office; it only receives filtered HTTP requests.
If we use GA4 Server-Side, do we still need a cookie banner?
▾
Yes, absolutely. Server-Side Tracking does not replace the consent collection required by the nFADP and the GDPR. However, the server allows for applying this consent much more strictly and sending modeled anonymous data (Consent Mode) if the user refuses cookies.
