Return Rate measures the share of units sold that customers send back and your team accepts within the policy window. It focuses on item counts, not dollars. Use it to surface fit issues, fragile packaging, misleading product details, and fulfilment mistakes that drive avoidable returns. Track it by SKU, variant, size, and channel to see where problems cluster.

Spend Lift is a loyalty metric that measures the increase in customer spending between two time periods, showing whether loyalty programs or promotions are driving real revenue growth.

Subscriber Growth Rate is the percentage change in an application's subscriber base from one period to the next. It signals whether a product is gaining or losing traction. The time period can be a week, a month, a quarter, or a year.

Time to Value (TTV) measures the elapsed time from when a user selects a product to the moment they first realize tangible benefit from it. Value is typically defined as completing setup and achieving a meaningful first outcome, not just finishing onboarding.

Transaction Recency is the average number of days since a customer's last purchase, measured across all repeat buyers. It indicates how quickly customers return to make additional purchases and is most useful for businesses where repeat transactions are expected, such as e-commerce, retail, and usage-based software.

Trial Conversion Rate measures the percentage of users that have converted to a paid account from a trial period. Commonly referred to as Free Trial to Paid Conversion Rate, this metric indicates product value by measuring the number of users that find enough value in the product to pay for it. Trial Conversion Rates vary based on the type of trial you use. In SaaS, the standard practice is to either have a freemium product or a free trial period that usually spans a couple weeks.

Trials is a count of the number of trial accounts started during a given period of time. The metric helps businesses gauge product interest, forecast conversions, and evaluate the effectiveness of their free trial model.

A True Trial is a trial user who returns to the product at least once within the first 7 days of signing up. True Trials measures early engagement quality for software companies that offer free trials, isolating users who give the product a genuine evaluation from those who sign up and never return. Tracking True Trials lets teams assess lead quality and conversion potential weeks before final conversion data is available.

Unsubscribes is the count of users who cancel or do not renew their subscription in a given period. Teams track this metric to catch at-risk customers early and act before the loss becomes permanent.

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.

Weekly Active Accounts measures the number of unique accounts with at least one user who has interacted with an application or platform in a week. An active account may include one or more users, who may each have varying degrees of activity.

Weekly Active Users (WAU) is the count of unique users who interact with an application or platform at least once in a given week. WAU tracks weekly engagement and includes both new and returning users.
