GA4 Agency

GA4 Agency:
set up Google Analytics 4 to make real decisions

GA4 is the central platform that connects all your marketing data. We set up, migrate and implement Google Analytics 4 so you have a reliable source of truth for business decisions — and so you understand why the numbers from Meta or Google Ads don't always match reality.

What we do

GA4 configured
for the business, not for the template

We implement GA4 thinking about the decisions your team will make with that data — not just turning on the default setup and looking the other way.

GA4 setup from scratch

Properties, data streams, enhanced measurement, custom dimensions and custom metrics tailored to your business.

Reconfiguration of broken GA4 setups

We audit inherited setups running on the default configuration and rebuild them around the business logic, so the data actually drives decisions.

Events and conversions

Definition of key events, primary and secondary conversions, full funnel mapping for your product or service.

Advanced audiences

Segmentation by behavior, value and lifecycle stage — exportable to Google Ads and other ad platforms.

GA4 Enhanced Ecommerce

Integration with Shopify, PrestaShop, WooCommerce and other CMSs for full purchase funnel tracking.

Looker Studio

Dashboards connected to GA4 with visualizations built for the business, not for vanity metrics.

BigQuery export

Access to raw data for advanced analysis, custom attribution models and connection with other data sources.

Attribution and models

Attribution model setup, channel comparison and identification of discrepancies between GA4 and ad platforms.

GA4 vs ad platforms

Understand the differences
to decide with criteria

When GA4 says one thing and Meta or Google Ads say another, it's not a bug: it's the natural consequence of each platform attributing from its own model. The question isn't which one is right, but which one to use for each decision.

  • Why GA4 says one thing and Meta says another

    Meta only sees the clicks and conversions that go through its pixel. GA4 sees the full funnel cross-channel. The discrepancy isn't a flaw — it's information.

  • Which one is the source of truth

    For per-channel investment decisions, the ad platform. For channel-mix and global attribution decisions, GA4. For business decisions, the back-office data.

  • How to build useful reporting

    We combine GA4 with ad platforms in the same dashboard, clearly marking which source feeds each metric so the read is honest and actionable.

Growzz methodology

How we implement GA4
step by step

Five phases so GA4 stops being a dashboard nobody looks at and becomes a real decision-making tool.

01

Audit of current setup

We review how GA4 is configured today — which events are tracked, which conversions count, where the gaps are — before proposing any changes.

02

Measurement logic definition

We design what is measured and how based on the business: which events matter, which conversions actually move the needle.

03

Technical implementation

Configuration, events, conversions, audiences and connection with ad platforms to enable audiences and cross-channel reporting.

04

Validation

QA via DebugView, comparison with ad platforms and review of data quality before signing off the implementation.

05

Reporting activation

Looker Studio, BigQuery exports when applicable and ongoing monitoring to keep the system healthy over time.

Frequently asked questions

Frequently asked questions
about GA4

How does GA4 relate to Consent Mode v2?

GA4 is designed to work with Consent Mode v2 natively. The right combination lets you comply with European privacy regulation without losing visibility on your data: when a user rejects cookies, GA4 still receives aggregate signals and models the lost conversions. Without Consent Mode v2 properly implemented, those users disappear from your analysis. We always work them as a single block on measurement projects.

Does GA4 alone comply with European privacy regulation?

No. GA4 is the measurement tool, but legal compliance is handled by the CMP (Consent Management Platform) and Consent Mode v2. We configure all three pieces — GA4, CMP and Consent Mode v2 — to work together and respect the user's decision on cookies, without sacrificing the ability to optimize campaigns with aggregate data.

Does GA4 work for ecommerce?

Yes. With GA4 Enhanced Ecommerce you can measure the full funnel: product views, add to cart, checkout, purchase. We integrate it with your CMS — Shopify, PrestaShop, WooCommerce — and connect it to ad platforms for audiences and conversions.

Why does GA4 give me different numbers than Meta or Google Ads?

Each platform attributes from its own model and only sees its own campaigns. GA4 sees the full funnel and lets you cross channels. They are not contradictory data — they are different perspectives. The key is knowing which one to use for each decision, and that's where we come in.

How much does a GA4 implementation cost?

Each project is analyzed individually. It depends on the current state of your measurement, the CMS, the complexity of the funnel and whether you need a setup from scratch or an audit on top of what already exists. We work without lock-in and build the proposal after a first conversation.
