Growzz methodology How we work
How we work
on web analytics
Five steps to make sure your measurement system supports business decisions, not the other way round.
01
Measurement audit
We review what you have, what is failing and what is not being tracked. Before proposing anything, we understand the starting point.
02
KPI definition
We identify which metrics to move based on business objectives. Measurement is designed to drive decisions, not to fill dashboards.
03
Technical implementation
GA4, GTM, data layer, server-side tracking, consent mode and connections to advertising platforms.
04
Validation and QA
Event, conversion, attribution and data quality testing. If measurement is unreliable, everything else is built on sand.
05
Reporting and ongoing monitoring
Business-oriented dashboards and periodic reviews to keep the system healthy and adapt it as the project evolves.

Frequently asked questions Frequently asked questions
Frequently asked questions
about web analytics
Why start with analytics before the channels?
Because without solid measurement you cannot tell what works and what does not. Activating Paid Media or SEO without proper analytics is investing budget without a real ability to optimize. Before proposing a growth strategy, in many projects we require measurement to be in order. It is the foundation everything else is built on.
What does a web analytics agency do?
Designs, implements and maintains the measurement system that allows decisions to be made with data. That includes GA4 setup, Google Tag Manager, data layer, custom events, conversions, server-side tracking, multi-channel attribution, dashboards and business-oriented reporting.
What is the difference between GA4 attribution and Meta or Google Ads attribution?
Each platform attributes according to its own model and only sees its own campaigns. GA4 is the source that connects all channels and shows the full funnel. That is why we use GA4 as the central measurement platform and compare it with the advertising platforms to understand discrepancies and decide with criteria.
What is server-side tracking and when do I need it?
Server-side tracking sends events from your server instead of from the user's browser. It reduces data loss caused by ad blockers, ITP and cookie restrictions. You need it when there are large differences between what your ad platform measures and what the business actually confirms. Each case is analyzed to decide whether the implementation is worth it.
Do you work on analytics for all your clients?
Yes, no exceptions. Analytics is a mandatory step in every Growzz project. We do not conceive a growth strategy without a solid measurement system behind it. It is our way of understanding digital marketing: with clean data, not with assumptions.
How much does a web analytics agency cost?
Each project is analyzed individually. The proposal depends on the current state of your measurement, the CMS, the complexity of your funnel and whether you need a new implementation or an audit on top of what already exists. We work without lock-in and build the proposal after a first conversation.
