The essentials
- Three levels: reading (management, sales), analysing (marketing), configuring (a technical lead). None of them needs the level above.
- The lead: one person in-house who masters level 3 and documents things. They are what makes the company self-sufficient.
- Formats: Google's free resources for the basics, a one-day in-house course for analysis, coaching for configuration.
- 90 days: a weekly 15-minute ritual around 5 figures is worth more than a day's training with no follow-up.
Most GA4 properties are under-used not for want of data, but for want of readers. The interface changed with the move from Universal Analytics, the reports are no longer where people looked for them, and teams stopped opening the tool. Building skills doesn't mean turning everyone into an analyst: it means giving each role the level it needs, and appointing a lead.
The three levels of mastery
| Level | Who | What they can do | Learning time |
|---|---|---|---|
| 1. Read | Management, sales, product managers | Open a dashboard, understand 5 to 8 metrics, ask the right questions | 2 hours |
| 2. Analyse | Marketing manager, communications officer | Navigate the reports, compare periods, segment, explain a change, build a custom report | 1 day + practice |
| 3. Configure | Analytics lead, webmaster, developer | Tag Manager, events, key events, consent, audits, documentation | 2 to 3 days + support |
The classic mistake is sending everyone on the same course. Management gets bored on Tag Manager triggers, the developer on reading reports, and nobody retains anything.
Level 1: making the data readable without learning GA4
Management won't open GA4, and that's fine. What they need: a one-page dashboard, metrics defined in a sentence, and someone to comment on them. The lever for building skills is therefore the management dashboard and a two-hour session to explain it. Advice for that session is in getting your board to read dashboards.
Level 2: training marketing to analyse
Your marketing manager should be able to answer "why did traffic fall this month?" on their own. The one-day programme:
- GA4's logic: events, sessions, users, key events (see GA4 events).
- The five reports to know and how to read them (see reading a GA4 report).
- Comparing, segmenting, filtering: finding the cause of a change.
- KPIs by family, and vanity metrics.
- Creating a custom report and a simple exploration.
- An exercise on the company's own data: every participant leaves with three findings and three actions.
That programme corresponds to our Google Analytics 4 course, delivered in-house, Qualiopi-certified and fundable through your OPCO. The decisive point is the last one: training on generic data is forgotten within two weeks; training on your data produces decisions the same day.
Level 3: a lead who configures and documents
A company self-sufficient on GA4 has someone able to create an event in Tag Manager, test it, mark it as a key event and document it in the measurement plan. That lead needn't be a developer: a marketing manager comfortable with the technical side, a webmaster, a digital project manager. Their training runs to two or three days (advanced GA4 + Tag Manager) then a few months of support from a consultant, in question-and-answer form. The skills to acquire are those listed in choosing a GA4 consultant, and the documents to produce are the deliverables of a GA4 provider.
The formats and what they cost
| Format | For which level | Cost | Effectiveness |
|---|---|---|---|
| Google's free resources (Skillshop, GA4 help centre) | 1 and 2, the basics | 0 € | Good for vocabulary, weak for practice |
| Tutorials and articles (like this hub) | 2 and 3 | 0 € | Good as a complement, requires self-discipline |
| A one-day in-house course on your own data | 2 | €600 + €200 per additional participant | High, if followed by a ritual |
| Advanced training + coaching | 3 | €1,500 to €3,000 | High, for creating a lead |
| Webinars | 1 and 2, keeping up | €0 to €50 | Useful for staying current |
The 90-day plan
- Week 1 : an audit or configuration by your lead or a consultant, so the data is worth reading in the first place.
- Week 2 : a one-page management dashboard and a two-hour session on how to read it.
- Week 3 : a one-day course for marketing on the company's own data.
- Weeks 4 to 12 : a weekly 15-minute ritual on five metrics, run by marketing, with one finding and one action noted each time. The lead handles the technical questions and builds up the documentation.
- Week 12 : a review, the questions left unanswered, and an adjustment to the dashboard.
How GreenRed helps
Rather than juggling several tools, GreenRed's Traffic module brings these metrics together in a single dashboard, compares them over time and tells you which actions come first. You can try it free, with no card, from the Pricing.
Frequently asked questions
How long does it take to master GA4?
Two hours to read a dashboard, a day's training plus a few weeks of practice to analyse the reports, two to three days plus ongoing support to configure and document. Nobody needs to master "everything": each role has its level.
Are Google's free resources enough to learn GA4?
For vocabulary and the basics, yes: Skillshop and the help centre cover the fundamentals. What they lack is practice on real data and answers to the questions specific to your site. Training on your own data, or ongoing support, closes that gap.
Should management be trained on GA4?
Not on the tool — but yes on reading the metrics. Two hours around a one-page dashboard is enough: what each metric measures, what a change means, what decisions it calls for. Management will never open GA4, and that's perfectly normal.
Can a GA4 course be funded?
Yes if it is delivered by a Qualiopi-certified organisation: your OPCO or France Travail can cover it. The French CPF scheme does not apply to non-certifying GA4 courses. Check with your OPCO before signing.
