The feature that helps track user interactions with specific elements on a web page is Events. Events in Google Analytics are designed specifically for monitoring actions that users take on your site that may not be captured by standard pageview tracking. These interactions can include clicks on buttons, downloads of files, video views, form submissions, and other specific user engagements.
By utilizing events, you can gain valuable insights into how users are interacting with your content and which elements are driving engagement and conversions. This information allows marketers and website owners to better understand user behavior, enhance the user experience, and optimize their content accordingly. Events provide a granular level of tracking that is instrumental for analyzing specific actions and their impacts on overall website performance.
While goals and custom dimensions also play important roles in analytics, they do not specifically focus on real-time tracking of user interactions with individual page elements. Tags are related to data collection mechanisms but do not inherently track interactions like events do. Thus, events are the most appropriate choice for tracking user interactions with specific elements on a web page.
