Monthly Active Users

Monthly Active Users (MAU) is a key metric that indicates the number of unique users who engage with a product or service within a given month.
Also known as:Active Users, Unique Users, User Engagement Metric, MAU

Definition

Monthly Active Users (MAU) is a crucial metric used in user analytics to assess the engagement and growth of a digital product or service. It counts the total number of unique users who interact with the application or website at least once during a specified month. This metric is vital for understanding user retention, engagement trends, and the overall health of the product.

MAU is particularly important in the fields of UX and product design as it provides insights into user behavior and can help inform design decisions. By analyzing MAU, UX professionals can determine how effectively a product meets user needs and identify areas for improvement.

In addition to tracking user engagement, MAU can also serve as an indicator of market reach and the effectiveness of marketing strategies. Fluctuations in MAU can reveal the impact of new features, updates, or promotional campaigns, making it a valuable tool for product managers and marketers alike.

Expanded Definition

The concept of Monthly Active Users originated from the tech industry as a way to quantify user engagement over time. Unlike Daily Active Users (DAU), which tracks daily interactions, MAU provides a broader perspective on user activity, allowing businesses to analyze trends over a longer period. This metric is particularly useful for subscription-based services and apps, where understanding long-term user engagement is essential to driving revenue and ensuring customer loyalty.

It is important to note that the definition of 'active' can vary between platforms. Some may define active users based on specific actions taken, such as logging in, completing a task, or making a purchase, while others may consider any form of engagement as a valid interaction. This flexibility allows businesses to tailor their metrics to best suit their specific goals and user behaviors.

Example

For instance, a social media app may track its MAU to determine the effectiveness of a recent feature addition that allows users to share stories. If the MAU increases significantly after the feature launch, it may indicate that users find the new functionality valuable and engaging. Conversely, if MAU declines, the product team may need to investigate potential areas of usability issues or dissatisfaction among users.
