Facebook shuffles the deck
Thursday, August 30th, 2007 by John BrianJust two days ago, I wrote a post about how some applications were cheating their way to the top of the “most installed” list on Facebook. It seems that they’re already taking action to curb these sorts of abuses, starting with changes to the code (someone with more programming
knowledge can probably fill in more here – if you’ve got a sense of what the code changes mean, post a link in the comments). But what I find more interesting is a new feature added today that tracks stats not solely by installs but by engagement. If you look at the application summary page today, you’ll see that instead of total installs, it now shows “Daily Active Users.” This change completely turns the application rankings on their head, and will likely have a major effect on how applications are developed and what gets installed.
So what is a “Daily Active User?” And what’s the percentage? Dave Morin explains on the Facebook Blog:
With a change this foundational to Facebook Platform’s measurement, we want to make sure that you completely understand how we will be measuring engagement. We define engagement as the number of users who touch your application every day (measured from midnight to midnight each day).
These touch points are:
- Canvas Page Views
- Link Clicks in FBML
- Mock-Ajax Form Submission
- Click-to-Play FlashThe number of engaged users is calculated by putting all of these touch points together. We display this as the number of “Daily Active Users.” Next to it we also show what percentage that is of the application’s total number of users.
So you can still figure out the gross reach of an application by taking the daily active users and dividing by the percentage. This leads to some new questions about what’s the most useful gauge of how much real influence an application has.
