FAQ – Everything you need to know about Data Agency
What is server-side tracking and why is it important?
Server-side tracking means sending tracking data from your server rather than from the user's browser. Unlike classic (client-side) tracking, it is not affected by ad blockers, Safari's ITP restrictions or the end of third-party cookies. The result: you recover up to 30% more data and significantly improve the reliability of your conversion measurement. It has become a must-have for any serious business in its data strategy.
What is the difference between Google Analytics 4 and Universal Analytics?
Google Analytics 4 (GA4) is the new Analytics generation, based on an event model (each interaction is an event) unlike Universal Analytics, which worked by sessions and page views. GA4 offers better cross-device integration, built-in machine learning (automatic insights, conversion modeling) and improved GDPR compliance. Universal Analytics was permanently discontinued in July 2024. We help you fully leverage GA4.
How does A/B testing work concretely?
A/B testing consists in presenting two different versions of a page, button or element to two random user groups, then statistically measuring which performs best. Concretely: we identify an improvement hypothesis (e.g. changing a CTA color), we create the variant, we serve it to 50% of traffic and analyze the results at a minimum 95% statistical significance. This process continuously and scientifically improves your conversion rates.
How do you ensure GDPR compliance of tracking?
We build GDPR compliance by design into your data infrastructure. This includes: a properly configured CMP (Consent Management Platform), Google Consent Mode v2 to adapt tracking to consent, IP anonymization, limited data retention and server-side tracking that respects user choices. We ensure each tag only fires with the appropriate consent while maximizing the quality of collected data.
How long does it take to see CRO results?
First CRO results are usually visible within the first 4 to 6 weeks. The initial UX audit often reveals « quick wins » (simple high-impact fixes) that can be deployed fast. For A/B tests, it typically takes 2 to 4 weeks per test depending on your traffic volume to reach statistical significance. Over a 6-month program, our clients see on average a 20 to 45% conversion rate improvement. The key is consistency: each test brings learning that feeds the next.
Do you offer training for our teams?
Absolutely. We offer tailor-made training adapted to your teams' level: GA4 introduction for marketing teams, advanced GTM training for technical profiles, dashboard reading for decision makers and A/B testing culture for product teams. Our goal is to make you autonomous in day-to-day data usage while remaining available for advanced, strategic topics. Every training includes complete documentation and post-training follow-up.
