MAU or Monthly Active Users is a widely used term to describe the number of unique customers who engage with an app or website within 30 days.

What is MAU(Monthly Active Users)?

MAU or Monthly Active Users is a widely used term to describe the number of unique customers who engage with an app or website within 30 days. All the brands use some unique identifier number to differentiate users from each other. These unique identifiers can be anything like a user ID, email ID, or user name. 

Identifying a different user can vary from brand to brand. It completely depends on the business vertical and the user’s business needs. This article will give you an elaborated view of MAU. But, to get it in a better way, this would be a correct statement that, “MAU should be examined concerning DAU.

Crucial Components of Monthly Active Users

If we want to understand every bit of MAU, then first, we should read up on the important components of MAU. Three components give this term a full frame in this technical realm. Here they are: 

Users: 

Users are the core component of MAU. Every unique user has to perform some sort of unique event inside the app or the website within 30 days. This in-app activity can be anything like “log in” or “add to cart.” But, every user will be counted as a single user in respective of how many time they’re logging into the app. 

Events that Users Do: 

How a user can be qualified as an MAU? See, this selected event completely depends on your company’s business vertical. But, in general, the qualifier event is “log in” or “opening the app.” This way, the measurement gets easy and accurate.

A Specific Time-frame: 

Here, we’re examining either the previous 30 days or the month before a specific event.

Why is Monthly Active Users an Important Metric?

MAU is critical because it allows companies to gauge how their app or website is performing. It indicates: 

  • How many people still care about using their product (in comparison to the previous month) 
  • If they are gaining or losing users 
  • If the changes or updates are doing what they were supposed to do 
  • If they’re getting regular users back 

For businesses, having knowledge of their MAU could determine the strategy of promotions, app updates, and/or financial choices. If your MAU are continuing to grow, that’s a fantastic sign, because it means people are using and achieving value from your product.

How are Monthly Active Users Calculated?

To compute MoAU, companies utilize analytics tools that track user usage. They will track how many unique users log into or use an app within the month.

Companies only count a user once in a month. It does not matter how often they interact with the app within the month. This helps to keep the Monthly Active User count unique and avoids duplicates.

Here’s a simple example of how it works:

  • A user opens an app once in May = 1 MAU
  • A user opens it 50 times in May = 1 MAU
  • A user does not open it at all in May = 0 MAU for May

Some apps will track Daily Active Users (DAU) or Weekly Active Users (WAU) but MAU gives a wider and more stable view of user engagement and usage.

Monthly Active Users on Major Platforms

MAU is a metric utilized by some of the most prominent platforms on the planet to measure success. Let’s explore a few real-world examples:

Facebook MAU

Facebook Monthly Active Users is one of the highest in the digital world, reaching more than 2 Billion people every month. MAU gives Facebook information on which features are popular and which features are in need of change. It also provides reassurance to advertisers that potentially millions of people, are active each day.

Instagram Monthly Active Users

Instagram MAU also reach the billions. People actively post stories, reels and photos onto the platform and this regular activity increases its MAUs. Provided global engagement continues at a high level, Instagram can use real user behaviour to launch new features and updates.

YouTube MAU

YouTube MAU are massive too. People engage with YouTube in a wide variety of ways, from watching how-to videos, to streaming live events. YouTube uses this MAU data to tell them how to deliver better video suggestions, add improvements to ads, and to enhance the overall user experience with video tools.

Benefits of Tracking Monthly Active Users

Understanding the number of MAU has many good things associated with it:

  • User Engagement – Let you know what users like or dislike.
  • Growth – Makes tracking growth or decline easier.
  • Retention – This lets you know when users are coming back or falling off.
  • Feature Testing – This lets you test new features and measure if they are used outside of initial testing.
  • Marketing ROI – Let you know if your marketing campaigns are working.

Whenever you see that the MAU are increasing, that is a terrible signal that your platform is connecting with people. When you see the MAU decrease, its time to start changing something.

Challenges of Measuring Monthly Active Users

MAU is a very simple idea but can be difficult to measure accurately: 

  • Multiple Accounts – One individual could have multiple devices/login accounts. 
  • Inactive Engagement – One person could open the app and not use it. 
  • Bots or Spam – Artificial users can inflate MAU. 

Companies need to use solid tracking systems to ensure they are measuring real, active users and not just open or automated traffic.

Final Thoughts

MAU is one of the best metrics to see how successful an app or platform truly is. It measures the users’ regular consumption of a service, allowing you to plan updates, modify features, or even secure new investors. 

Facebook, Instagram, and YouTube depend upon this metric every day. It doesn’t matter if you’re talking about Facebook Monthly Active Users, Instagram MAU, or YouTube Monthly Active Users; this data tells the story of how people connect, share and use platforms online.

Even if you’re not building an app, both understanding how MAU functions and knowing what the actual numbers are helps you to understand which platforms are growing and/or why. In an increasingly digital world with seemingly endless choices, this metric gives you a simple number to understand how users are consuming services and what they truly love to interact with.
