Loyalty Metrics

Active Users in GA4 represents the number of distinct users who engaged with your website or app during a specified time period. A user is considered "active" when they trigger an engagement session, which occurs when they stay on your site for 10 seconds or longer, have a conversion event, or have 2 or more page or screen views. This metric provides a foundational understanding of your audience size and engagement levels, replacing the traditional "Users" metric from Universal Analytics with a more engagement-focused approach. Unlike simple visitor counts, Active Users emphasises meaningful interaction with your content, filtering out users who immediately bounce or show no genuine interest in your site. This makes it a more reliable indicator of your actual engaged audience size.

Average Purchase Frequency is the average number of times a customer makes a purchase within a defined period. It measures how often customers return to buy, helping businesses understand purchase patterns, inform loyalty strategy, and improve customer lifetime value.

A Customer Health Score is a single, calculated number that reflects a customer's health across multiple dimensions. By monitoring Customer Health Scores, you can detect early signals of increased friction or declining customer engagement, and identify highly engaged clients who would make excellent advocates.

Customer Lifetime Value (LTV) represents the total net revenue a business can reasonably expect to generate from a single customer account throughout the entire duration of their relationship. This metric goes beyond simple transaction analysis by incorporating customer retention patterns, purchasing frequency, and profit margins to provide a comprehensive view of customer economic value. LTV serves as a cornerstone metric for strategic decision-making, enabling businesses to optimise acquisition spending, prioritise retention efforts, and identify high-value customer segments that drive sustainable growth.

Customer Retention Rate is the percentage of existing customers a business keeps from one period to the next, excluding newly acquired customers.

Daily Active Users (DAU) is the count of unique users who interact with an application or platform on a given day. DAU measures daily engagement and includes both new and returning users. Unique users are identified by a username, email address, or user ID, and active users can be paying or non-paying.

DAU Growth Rate is the percentage change in Daily Active Users (DAU) over a defined period. It measures how quickly an active user base is expanding and can indicate the effectiveness of sales and marketing efforts, product-market fit, and overall engagement health.

Email Reply Rate measures the percentage of sent emails that generate a reply. This metric is crucial for assessing the effectiveness of email marketing campaigns, customer engagement, or team communication efforts. Higher reply rates typically signify that the content of the email is resonating with the audience, prompting them to engage in the conversation. However, it's important to keep in mind that various factors can influence Email Reply Rate, including the quality of the email content, the subject line, and the relevance to the recipient.

Monthly Active Users (MAU) is the count of unique users who interact with an application or platform at least once in a given month. MAU tracks engagement across both new and returning users, and serves as an early indicator of retention risk or growth momentum. Unique users are identified by username, email address, or user ID. Both paying and non-paying users count, including those on free trials.

Net Promoter Score (NPS®) is a measure of a customer base's willingness to promote a product or service to colleagues and friends. It is based on the results of a current customer survey, which asks respondents to answer the following question: “how likely is it that you would recommend (brand or product X) to a friend or colleague?” Responses, with 10 being the highest, are grouped as follows: 10s and 9s are brand ‘Promoters’, 8s and 7s are ‘Neutrals’, and any responses below 7 are brand ‘Detractors’.

Net Revenue Retention (NRR) Rate, also known as Net Dollar Retention (NDR), is the percentage of recurring revenue retained from existing customers in a defined time period, including expansion revenue, downgrades, and cancels. This churn metric gives a comprehensive view of positive as well as negative changes with respect to customer retention.

Renewal rate is the percentage of customers who renew their subscription within a defined invoicing cohort, measured against the total customers up for renewal in that period. It tracks churn and retention at the cohort level rather than against total customer count, making early trends easier to spot.
