Setting Up Google Analytics 4

Universal Analytics (UA) measured website activity in sessions and pageviews. Google Analytics 4 replaced it in 2023 with an event-based model that tracks every user interaction as an event, providing a more flexible and privacy-resilient framework that works across websites and mobile apps in a single property.

To create a GA4 property, go to Google Analytics, click Admin, then Create Property. Enter your property name, reporting time zone, and currency. GA4 creates a default web data stream — you will use the Measurement ID from this stream to install the tracking code on your website.

You can install GA4 directly by pasting the gtag.js snippet into the head section of every page on your website, or through Google Tag Manager (GTM) by creating a GA4 Configuration tag. GTM is preferred for most sites because it centralizes all tracking tags and lets marketers make updates without touching code.

A data stream is a source of data flowing into your GA4 property — typically a website, an iOS app, or an Android app. Each stream has its own Measurement ID. If you have both a website and a mobile app, configure separate streams for each so you can analyze cross-platform behavior in a unified property.

GA4 automatically tracks common interactions through enhanced measurement: page views, scrolls (90% scroll depth), outbound link clicks, site search queries, video engagement, and file downloads — all without additional code. Verify these settings in Admin under Data Streams to ensure the events you need are enabled.

After installing GA4, immediately open the Real-Time report to verify data is flowing correctly. You should see your own visit appear within seconds. If nothing appears after five minutes of active browsing, recheck that the Measurement ID in your tag matches the ID in the GA4 property exactly.

By default, GA4 retains event-level data for only two months. Change this to 14 months immediately after creating your property by going to Admin, then Data Settings, then Data Retention. Longer retention is essential for year-over-year comparisons in your Exploration reports.

Connecting GA4 to Google Search Console surfaces organic search performance data — queries, impressions, clicks, and average position — directly inside GA4 reports. This connection is made in Admin under Product Links and requires you to be a verified owner in Search Console for the same domain.

Linking GA4 to Google Ads allows you to import GA4 key events (conversions) directly into Google Ads for campaign optimization, and enables GA4 audiences to be used for Google Ads remarketing. The link is created in Admin under Product Links by a user who has admin access to both accounts.

GA4 has four roles: Viewer, Analyst, Editor, and Administrator. Assign roles at the property or account level in Admin under Account or Property Access Management. Follow the principle of least privilege — most team members need only Analyst access, while Editor access should be reserved for those who configure settings.

Your own team's visits to the website will inflate traffic numbers and skew engagement metrics if not filtered out. Create an internal traffic rule in GA4 Admin by specifying your office IP addresses, then activate a Data Filter to exclude those sessions from your reports. This ensures your analytics data reflects genuine visitor behavior only.

Test your understanding of Google Analytics 4 setup essentials.

Setting up GA4 correctly requires creating a property with the right time zone, installing tracking via gtag.js or GTM, configuring data streams for web and app, enabling enhanced measurement, verifying in Real-Time, extending data retention to 14 months, linking Google Search Console and Google Ads, configuring user roles with least-privilege access, and filtering out internal team traffic so your reports reflect genuine visitor behavior.
