How to Set Up Google Analytics 4

Why GA4 Matters

Google Analytics 4 has been the only supported analytics platform from Google since July 2023, when Universal Analytics was permanently shut down. The switch is not cosmetic: GA4 uses a fundamentally different event-based data model. Where Universal Analytics counted sessions and pageviews as its core metric, GA4 records every user interaction as an event. This makes it possible to track the same user across your website and mobile app, measure scroll depth and video views out of the box, and build audiences based on specific sequences of actions. If you want to understand how visitors actually move through your site and which pages lead to contact requests or purchases, GA4 gives you the tools to do that. It also integrates directly with Google Ads, which makes campaign attribution more accurate.

The Six Steps to Get Tracking Live

Start by going to analytics.google.com and creating an account under your company name. Inside that account, create a GA4 property and enter your website domain and time zone. Google will generate a Measurement ID in the format G-XXXXXXXXXX: save this.

To install the tracking tag, the recommended route is Google Tag Manager. Create a new tag of type “Google Analytics: GA4 Configuration”, paste in your Measurement ID, and set it to fire on all pages. Publish the container. Alternatively, paste the GA4 snippet found under “Data Streams” directly into the <head> of your site template.

Once the tag is live, open your website in a browser and check the Realtime report inside GA4. Your own visit should appear within 30 seconds. If it does not, double-check that the tag published correctly and that no browser extension is blocking the request.

Setting Up Conversions

A visit only becomes valuable data when you track what that visitor did. In GA4, conversions are based on events. Some events are collected automatically: page_view, first_visit, scroll, and session_start. Others, like a contact form submission or a file download, you need to configure yourself.

The cleanest method is to create a custom event in Google Tag Manager that fires when a specific action occurs, for example when a form confirmation page loads or when a button with a particular class is clicked. Name the event clearly, for example contact_form_submit, and then go to “Configure > Events” in GA4 and toggle that event as a conversion. Within 24 to 48 hours, GA4 will start attributing that conversion to the traffic sources that brought in those visitors. This data is what connects your marketing spend to actual business outcomes.

Privacy and GDPR Considerations

GA4 can be configured to meet GDPR requirements, but it does not do so by default. IP anonymization is active in GA4 from the start, which is an improvement over Universal Analytics. However, GA4 still sends data to Google’s servers, which in the EU requires a valid legal basis and typically explicit user consent before the tag may fire.

The practical solution is to use a consent management platform (CMP) to block the GA4 tag until the visitor accepts analytics cookies. Pair this with Google Consent Mode v2, which allows GA4 to model conversions and traffic estimates even for users who decline, without collecting personal data from them. Set your data retention period to 14 months in GA4’s settings. These three measures together make GA4 workable within a GDPR framework for most European businesses.

The Reports That Matter Most for Small Businesses

You do not need to explore every corner of GA4 to get useful insights. Four reports cover most business questions. The Acquisition report tells you where your visitors come from: organic search, direct, paid, social, or referral. This helps you understand which channels are actually working. The Engagement report shows time on page, scroll depth, and which pages have the highest exit rates, pointing you toward content that needs improvement.

The Conversions report ties everything together: how many goal completions did you get, and from which source? If you have set up events correctly, this report shows you the direct link between traffic and business outcomes. Finally, the Realtime report is useful when you launch a campaign or publish new content: you can see immediately whether traffic is landing and whether the tracking is responding. Understanding these four reports puts you ahead of most small business owners who install GA4 but never open it.

Our tip: Create a custom GA4 dashboard with just the Acquisition, Conversions, and top-10 pages reports and bookmark it. Check it every Monday morning for 10 minutes. Consistency beats deep-dive sessions that never happen.
