GA4: What you need to know to get started
Google Analytics 4 can be a little overwhelming for first-time users. The wealth of data and insights it provides can feel second to the wealth of new terms and acronyms you’ll encounter when using it. We understand GA4 can seem confusing and difficult to navigate at first. That’s why this page will offer you a glossary of some of the most common terms and acronyms used in GA4, to help you make sense of it all.
With a little knowledge under your belt, you’ll be able to start using this powerful tool like a pro!
- Bounce rate: the percentage of visitors who leave your site without taking action, like clicking a link or making a purchase. Users who bounce from your site only view a single page and do not convert. In GA4, bounce rate has been replaced by engagement metrics known as “Engaged Sessions.”
- Engaged Sessions: describes the percentage of sessions where users are actively engaged with your website. A session is considered “engaged” if users meet any of the following criteria:
- On a page for at least 10 seconds
- Had one or more conversion events
- Viewed two or more pages
- Engagement Rate: the percentage of sessions that were engaged sessions. In a way, engagement rate is the exact opposite of bounce rate.
- Custom Audiences: in GA4, this comes equipped with two audience types out-of-the-box — All Users and Purchasers. Building custom audiences allows you to group users based on similar actions or dimensions. Custom audiences can be used for retargeting campaigns and comparisons in GA4 reports. In addition to building custom audiences of your own, GA4 offers a range of suggested audiences, including templates and predictive capabilities.
- Events: describes any interaction on your website or app. Unlike Universal Analytics, which tracked users by sessions, Google Analytics 4 tracks users by events, connecting the user journey across multiple sessions. Types of events include:
- Automatically collected events, or any basic interaction with your website.
- Enhanced measurement events, or interactions with content on your website.
- Recommended events, or events that you implement.
- Custom events, or self-defined events. Custom events don’t show up in most built-in reports and instead require custom-built reports.
