Total time spent per user to be a proxy for how much value users are extracting from the respective app’s network.&nbsp;The attention captured metric is the answer to the age-old question, “Is this worth my time?” Of course, not all time spent in apps is equally valuable, from a business standpoint. Consuming TikTok videos for an hour is a dramatically more monetizable behavior than corresponding with friends on Facebook Messenger all day.&nbsp;

Total Time Spent 

How many users keep using the app post install? Broadly, messaging apps’ high retention rates are emblematic of network effects: Users seek to communicate with their friends and thus join the networks where their friends are. The more friends a user has on an app, the more valuable the network and the app becomes to the user.

Retention

Two of the fastest growing categories across the social app ecosystem are:&nbsp;<ol><li>Friend discovery: platforms that allow members to discover and connect with one another, often through common interests.</li><li>Vertical communities (those that enable further engagement around specific subjects or activities).</li></ol>

Attention has 2 components: addiction and absorption. An app can be successful with a high number of short sessions (like WhatsApp) or with infrequent but long (like Goodreads).

The Attention Equation

DAU/MAU indicates a product’s “stickiness.” For example: a DAU/MAU ratio of 33 percent would mean that the average user of said app views it 10 out of 30 days in a month.DAU/MAU doesn’t tell the whole story:<ul><li>Those who download the SoundCloud mobile are likely to listen to a lot of music compared to web users. For this reason, in social, DAU/MAU levels are often highest around media consumption.</li><li>Engagement in dating apps tends to be skewed around a core of super-users. Not everyone is looking for love, but those who are are highly active on the app.&nbsp;</li></ul>

Stickiness (DAU/MAU)

This pretty much correlates with how people use their phone: playing games, messaging friends, talking about games on Discord, and listening to music.

Absorption

When assessing a social app’s potential, what does “good” look like, anyway? The most important metrics—and benchmarks to aspire to—according to the data.
