Mobile Applications have changed how businesses are measuring user engagement. Many websites have typically measured user engagement by page views per users or time spent per user on site. Traditionally websites want users to spend as much time as possible on their site, as that mostly translates into increasing chance the user will spend $ or it generates more ad revenue (Of course there are exceptions like payment space or checkout flows, where the success is measured by how quickly and conveniently users and get the task done.) But Mobile Applications have changed the way we think about engaging users. Users are not going to spend hours or even few continuous minutes within the Apps. They are typically using the Apps on the go and they want instant gratification. More and more App developers are offering features/tools that can be accessed and completed with ease and speed. But they also want to bring them back as often as possible. So here are some of the sample KPIs for measuring engagements in Mobile Apps: Day part volumes - Softer peak hours and well distributed Actions throughout the day means users want to use App frequently. Don’t be discouraged if the visits are only few seconds long, it’s typical of App users. Velocity of Actions (most analytics tools prefer to tag them as Events) - The more clicks within the App, the more users are engaged (with of course exception of reading or video Apps). Feedback score volumes. The qualitative feedback is just as important. Always provide a feedback button within your App. In my experience, within App feedback volume far surpasses App store feedback. The more users are engaged, the more feedback you are going to get, even negative feedback is better than no feedback. At lease negative feedback provides you hints on what you need to change to retain the users!
