Which of the following can be considered an event in Google Analytics 4?

In Google Analytics 4 (GA4), an event is a crucial element as it encompasses a wide range of user interactions with a website or app. A pageview is indeed categorized as an event because it tracks when a user views a page on your site. This interaction helps provide insights into user behavior, including which pages are most visited, how long users stay on those pages, and the overall engagement of users with the content.

While sessions are important in understanding user interactions over a certain time period, they are not categorized as events themselves in GA4. Similarly, transactions, while they can be tracked as events in eCommerce setups, are more specific actions related to commerce rather than a general event classification. User is a dimension that describes the characteristics of the individuals interacting with your site and is not an event on its own. Thus, recognizing pageviews as events is essential for analyzing how users interact with and navigate through your content in GA4.
