Google Analytics 4 for e-commerce

Google Analytics 4:
numbers you can act on.

Do you know where your customers give up, and which advertising really pays? Badly set up — the out-of-the-box state —, Google Analytics tells you nonsense. I configure it as part of your e-commerce projects, on PrestaShop, Shopify, WooCommerce or a custom-built site, for reliable numbers that guide your decisions and your advertising.

In detail

GA4 mesure mal par défaut. Les événements standards — les actions comptées d'origine — suffisent pour du trafic, pas pour comprendre un tunnel d'achat : il faut déclarer les étapes qui comptent pour votre activité, transmettre la valeur des commandes, exclure votre propre trafic et celui de vos prestataires, et vérifier que les données remontent réellement — beaucoup d'installations perdent une part significative des conversions, les ventes comptées, sans que personne s'en aperçoive. S'y ajoute le volet réglementaire : bandeau de consentement, Consent Mode — le mécanisme qui adapte la mesure au choix du visiteur —, anonymisation.

Je configure GA4 de bout en bout et, quand c'est utile, je branche un suivi côté serveur pour les événements que les bloqueurs de publicité font disparaître.

Features

What you get.

Seeing where you lose customers

The whole journey tracked: pages viewed, add-to-carts, checkout steps, purchases with their value and margin. The foundation for understanding where things stall.

Counting what counts for you

A purchase, a contact request, a newsletter signup, a basket above a set amount: the goals measured are yours, not the factory presets.

Feeding your advertising

Useful visitor groups (engaged visitors, abandoned carts, best customers) sent to Google Ads for retargeting and reaching similar profiles.

Linked to your Google visibility

Connected to Search Console, the Google tool that shows your rankings: which searches bring visitors, to which pages, and what they do next.

Playing by the cookie rules

Measurement automatically adapts to the visitor's choice on the cookie banner (Consent Mode v2). Compliant with the GDPR and with the CNIL, the French authority, without skewing your numbers.

A dashboard you can read

The indicators that matter to you, clearly presented (Looker Studio, Google's dashboard tool, or GA4): sales, conversion rate, acquisition channels, a customer's value over time.

FAQ

Frequent questions

Is GA4 really different from the old Universal Analytics?

Yes, completely: GA4 counts visitor actions (page views, purchases) where the old version mostly counted visits, handles conversions differently, with a redesigned interface. A configuration simply carried over from the old Analytics is almost always incomplete for an online store.

Is it compatible with GDPR and consent banners?

Yes, thanks to Google's Consent Mode v2: measurement adapts to each visitor's choice (accepted, refused, partial). Data is still collected for those who consent, and nothing is collected on those who refuse.

Which platforms do you configure GA4 on?

PrestaShop, Shopify, WooCommerce, WordPress or any custom site. Generally via Google Tag Manager, the tool that centralizes measurement scripts: changes then need no edits to the site's code.

How much does a GA4 setup cost?

On a creation or redesign project, the setup is included. As a standalone service on an existing site: €400 to €900 depending on the complexity of the purchase journey and the number of actions to measure (purchases, add-to-carts, forms and so on).
