GA4 replaced Universal Analytics in 2023 and works differently from older versions. Here is how to set it up correctly and what to actually track for a service business.
Why GA4 works differently from older analytics and what to expect
Google Analytics 4 uses an event-based data model instead of the session-based model used by Universal Analytics. In older versions of Analytics, a pageview was the primary unit of measurement and everything else was measured relative to it. In GA4, every user interaction including pageviews, scrolls, clicks, form submissions, video plays, and file downloads is an event. This change makes the platform more flexible but also requires different thinking about how you set up and interpret reports.
GA4 also uses machine learning to fill in data gaps caused by cookie consent limitations and ad blockers, which means the numbers you see are modelled estimates rather than exact counts in some cases. Understanding this distinction helps set realistic expectations when reviewing traffic reports and comparing GA4 figures to older analytics data.
Installing GA4 on your business website
To install GA4, create a Google Analytics account at analytics.google.com and set up a new Property. Within the Property, create a Web Data Stream for your website and copy the Measurement ID, which starts with G-. The simplest way to add GA4 to your site is through Google Tag Manager, which allows you to manage all tracking tags without editing website code directly.
In Google Tag Manager, create a new tag of type Google Analytics: GA4 Configuration, paste your Measurement ID, set the trigger to fire on All Pages, and publish the container. If you prefer to install directly without Tag Manager, most CMS platforms including WordPress, Webflow, and Squarespace have settings or plugins that accept a GA4 Measurement ID and handle the installation automatically.
Setting up conversion events for a service business
The most important conversion events for a service business are form submissions, phone number clicks, and email link clicks. GA4 automatically tracks some events like page scrolls and outbound clicks, but form submissions require additional configuration. In Google Tag Manager, create a tag that fires a custom event called generate_lead when your contact form is submitted successfully, targeting the thank-you page URL or the form submission confirmation that appears after a successful send.
Phone number clicks can be tracked with a GA4 event tag triggered by clicks on tel: links. In your GA4 Property, go to Events and mark these custom events as conversions. This tells GA4 to count them as key actions and include them in conversion rate calculations. Once marked as conversions, you can see conversion rates per traffic source, per landing page, and per campaign in your reports.
The reports that matter most for a small service business
The Acquisition overview report shows where your visitors are coming from: organic search, direct, referral, paid, or social. For most service businesses, organic search should be the largest and growing channel over time. Compare channel performance quarterly and look for trends rather than obsessing over week-to-week fluctuations.
The Pages and Screens report under Engagement shows which pages are receiving the most views and which have the highest engagement rates. Look for service pages that have high traffic but low engagement time, as these may need content improvements. The User acquisition and Traffic acquisition reports show the sources of both new users and all sessions, which helps you understand both audience growth and returning visitor patterns.
Connecting GA4 to Google Search Console for richer insights
Linking your GA4 property to Google Search Console gives you access to organic search performance data inside Analytics without switching between tools. After linking, you can see which search queries drove traffic to which landing pages, and you can correlate search performance with on-site engagement and conversion data in the same interface.
To link the properties, go to Admin in GA4, navigate to Search Console Links, and follow the connection steps. Both properties must be owned by the same Google account. After linking, the Google Organic Search Traffic report under Acquisition will show impressions, clicks, click-through rate, and average position from Search Console alongside engagement metrics from GA4.
Frequently asked questions
How long does GA4 take to start showing data after installation?
GA4 typically starts showing real-time data within minutes of installation. Historical reporting data begins accumulating from the first day the tracking is live. There is no historical data from before installation.
Can I have both GA4 and Universal Analytics running at the same time?
Universal Analytics stopped processing new hits in July 2023, so it is no longer active. GA4 is the only current version of Google Analytics and cannot run alongside the old version.
