Trials is a count of the number of trial accounts started during a given period of time. The Trials metric helps a business gauge interest in their product and make sales predictions.

A True Trial is defined as a user who starts a trial and comes back a second time within the first 7 days. The True Trials metric is meaningful for any software company that offers prospects a trial before they choose to buy. Prospects who sign in twice within the first 7 day period are more likely to become paying customers. Tracking True Trials enables you to assess lead quality, product engagement, and probability of a win much earlier than only looking at Win Rate.

User Engagement is a foundational GA4 metric that measures the total time your website or app was in the foreground of users' devices during a specified date range. This metric captures the aggregate engagement time across all users and sessions, providing a comprehensive view of total user attention your digital property receives. Unlike user-averaged metrics, User Engagement represents the raw sum of all engagement duration, making it particularly valuable for understanding overall content consumption and audience reach. The metric only counts time when your site or app is actively in the foreground and meets GA4's engagement criteria (sessions lasting 10+ seconds, containing conversion events, or having multiple page/screen views), ensuring the measurement reflects genuine user attention rather than passive or accidental visits.

Users represents the count of unique individuals who have visited your website during a specified time period, encompassing both new and returning visitors. In Google Analytics 4 (GA4), this metric is tracked through client IDs that are automatically assigned to each unique visitor upon their first visit to your site. This identifier allows the platform to distinguish between different individuals and prevents double-counting when the same person visits multiple times within the measurement period.
