what is monthly active users mau 
monthly active users mau is a key performance indicator kpi used by social networking and other companies to count the number of unique users who have visited a site within the past month websites generally recognize monthly active users via an identification number email address or username mau helps to measure an online business s general health and is the basis for calculating other website metrics mau is also useful when assessing the efficacy of a business s marketing campaigns and gauging both present and potential customers experiences investors interested in the social media industry pay attention when companies report mau as it is a kpi that can affect a social media company s stock price who uses mau and how all too often companies do not the same parameters when calculating mau and there are no industry standards for defining key metrics like user and active for this reason critics of mau believe that the metric creates unfair comparisons among competitors others think mau is useful only in combination with other qualifying metrics and some wonder if it is relevant as a quantitative assessment mau tabulates the number of visitors there is no component that accounts for the depth or quality of a user s experience for example when calculating mau some companies consider a user as someone who has accessed their site for other businesses a user is one who has created a log in and password in others an active user must meet specific requirements defined by the company like many business metrics mau s usefulness depends on the company its services its competitors and its audience for example meta meta formerly facebook defines a monthly active user mau as a registered and logged in user this user must have interacted with facebook through the company s website or a mobile device or used its messenger application and is also a registered user in the last 30 days as of the date of measurement meta also tracks daily active users daus who must meet the same requirements as maus to count but meet those requirements on a daily rather than monthly basis x formerly twitter on the other hand stopped tracking monthly active users before it was acquired by elon musk and renamed x corp instead it looked at what it called monetizable daily active usage or users or mdau twitter defined mdau as people organizations or other accounts who logged in or were otherwise authenticated and accessed twitter on any given day through twitter com or twitter applications that are able to show ads so the difference begs the question if twitter s mau did not include the same engagement variables as meta s mau was the metric an apt comparison of the companies site usage limits of mauthe fact that there are no uniform standards for the individual components of mau and other metrics used to quantify trends in social media makes for a slippery playing field in 2015 meta revised its definition of mau noting that it no longer counted people who were not active facebook users but who shared content only via another site that integrated within the facebook login upon acquiring instagram and whatsapp meta made more adjustments to its user metrics in 2022 it published plans to further change how they measure usage in its annual filing the company has started using family metrics that measure monthly and daily active people map and dap across its family of platforms family monthly active people increased meta s metric by 2 year over year compared to monthly active users likely because it accounted for users across all its platforms the change appears necessary because meta has users with multiple accounts on several linked platforms so there was no way to accurately estimate usage using mau for example according to its annual filing it had 2 96 billion family dap for december 2022 while there were 2 0 billion dau for the same month family map averaged 3 73 billion that december while mau was 2 96 for the month a clear distinction exists between measuring active people and active users nearly one billion people s usage is not captured if the company relies on mau while seemingly an apt move on meta s part this begs the question with social media platforms becoming more centralized have others also decided to change their usage calculations if not how do they compare their success in attracting and maintaining a user base beside year over year numbers
