Google Analytics 4 Certification: Free Skillshop Guide and What to Study

The Google Analytics certification is free, it is run by Google on Skillshop, and it now covers Google Analytics 4 (GA4). I passed it in October 2026; the verify link is on my About page.

This guide covers what to study, how to practise with real data for free, and how the assessment works.

Why GA4 is worth learning

Every ad, post and email you run eventually leads to a website or an app. GA4 tells you what happened next: which pages people read, where they came from and whether they took the action you wanted.

Without analytics you are guessing. With it, you can say "this campaign brought 40 enquiries and that one brought 4", and move money to what works. That is the heart of performance marketing.

How the certification works

• Where: Google Skillshop, search "Google Analytics Certification".
• Cost: free.
• Format: a timed online assessment. Google's Skillshop certifications need 80% or more to pass. The intro screen shows the time limit before you start.
• If you fail: you can retake after a waiting period, usually one day.
• Valid for: one year.

Take it in one sitting, in a quiet place, on a laptop. The timer keeps running if you step away.

What to study

The course on Skillshop covers everything, but these are the ideas you must really understand:

Accounts, properties and data streams

• An account holds one or more properties.
• A property is usually one business or website.
• A data stream is one source of data inside a property: a website, an iOS app or an Android app.

Events and key events

In GA4, everything is an event: page views, scrolls, clicks, video plays, form submits. Some are collected automatically, some with "enhanced measurement", and some you set up yourself.

A key event is an event you mark as important, such as generate_lead or purchase. On this website, for example, a click that opens WhatsApp or email to contact me is sent to GA4 as a generate_lead event.

Reports and explorations

• Reports are the ready-made screens: acquisition (where people came from), engagement (what they did) and monetisation.
• Explorations let you build your own analysis: funnels, paths and segments.

Users, sessions and engagement

Know the difference between a user, a session and an engaged session, and what engagement rate means. Several questions test exactly these definitions.

Audiences and links to Google Ads

Audiences group users by behaviour, such as "visited the pricing page but did not enquire". Linked to Google Ads, they can be used for remarketing.

Privacy and data settings

Data retention, consent and what GA4 does not collect. Know where these settings live.

Practise with real data for free

Reading is not enough. Two free ways to practise:

1. Google's GA4 demo account. Google provides a demo property with real data from the Google Merchandise Store. Search "GA4 demo account" on Google's help centre to open it. Click through every report the course mentions.
2. Your own small site. Set up GA4 on a free website or blog. Even a few visitors a day teaches you more than any video.

My study routine was simple: one course module, then 15 minutes finding the same thing in the demo account.

Test yourself with these questions

If you can answer these in your own words, you are close to ready:

1. What is the difference between a property and a data stream?
2. Which events does GA4 collect automatically on a website?
3. How do you mark an event as a key event?
4. When would you use an exploration instead of a standard report?
5. What is an engaged session?
6. How would you check which source brought the most key events last month?

After you pass

• Add it to LinkedIn under Licenses and certifications with the credential link.
• Write a one-page report on a real site's data. A short, honest report is a better portfolio piece than the certificate alone.
• Learn Google Tag Manager next, then pair analytics with ads: Google Ads certification guide.
