“I frankly don’t give a shit if Instagram has more people looking at pretty pictures.”
Monthly Active Users (MAU) is the number of unique users who have interacted with the community in a month. This is different from visitors. Visitors include unregistered readers or readers who haven’t logged in.
Every time a reader logs into a site with Facebook Connect, and his or her activity - a like, a comment or a share, is posted on facebook.com, it counts as an action towards a monthly active user.
Does this definition impact how important MAU is as a metric for marketers?
MAU is a benchmark, a report card so to speak for the platforms, but the real question for marketers is, are my customers on that platform and how engaged are they?
