Engagement Index

Last Updated: Nov 21, 2012 03:01PM PST

ApScience provides you with the capability to better understand the degree to which your application users are engaged by letting you assign an Engagement Index to any event. The Engagement Index is a value that you decide upon.  For instance, you may decide that someone who reaches the level 5 event in a game is more engaged then someone who only reached the level 2 event, so you may assign an an Engagement Index of 2 to the level 2 event and an Engagement Index of 5 to the level 5 event.  These values are tracked for unique users when they hit any event that has an Engagement Index associated with it. The values are then used to provide information in multiple reports and analyses so that you can better understand the Engagement Index and Average Engagement per User (AEPU) associated with users, segments, events, applications, cohorts, and other key data points.

You can select event attributes that represent engagement OR set a constant numeric value for an engagement event.

In order to setup and use an Engagement Index, you need to:

  1. Go to My Events, find the event that you consider to be an engagement event, and click on Assign Engagement.
  2. You will then be presented with the option of selecting an attribute (if you have instrumented your application with an event that has an attribute representing engagement) OR a numeric value.   For example,  if you use an attribute,  you could have an InviteFriends event with a NumFriendsInvited attribute to be used for tracking of engagement. NOTE: The ability to choose an attribute will not be shown if you have not instrumented any attributes for the event.
  3. Save the engagement assignment. If an engagement definition has already been assigned, then you will be able to change or remove the engagement selection.
  4. From this point forward, Apsalar will record the engagement value for all occurrences of the specific event using the value of the engagement selection.  In the case of the attribute, all values reported in events will be used.  The engagement index information will be used for all reports that provide engagement information.

Here are some important rules regarding the selection of an Engagement Index:

  • There are not any data types associated with Engagement Index values. You should make sure that all Engagement Index values within a single application represent values that are consistently meaningful to your analysis.
  • An event may have both an Engagement Index and Revenue associated with it. For instance, a purchase event could have Revenue associated with the amount of the purchase and an Engagement Index value representative of the purchase event.

There are some also some operational facts with respect to Engagement Index:

  • It is OK to change an event’s Engagement Index, however, all data that has been recorded for using the previous value of the Engagement Index will not be modified. All of this data will be used when aggregating the Engagement Index data over a time period, however, you should be able to view specific periods of data by selecting an appropriate time period when allowed by a report.
  • Engagement Index reporting is not applied across all applications, meaning that there is not a roll-up of all applications’ Engagement Index values. Engagement Index and AEPU are only relevant to the application in which it is defined.

Engagement Index data will be used for the following types of reports:

  • Dashboard — There is a dashboard snapshot that displays Revenue and Engagement data.  The Engagement Index and AEPU for a selected application will be shown in this snapshot. You can also view the Engagement Index and AEPU by segments.
  • Trending Analysis — Metrics for Engagment Index and AEPU have been added to the trending reports. You will only be able to select these metrics if you have also selected a specific application.  Select them as you would any other metric.
  • Cohort Analysis — The cohort-based engagement analyses now provide views by Engagement Index and AEPU.  In addition, you can view data for the roll-up of all your Engagement events, treated for reporting purposes as a single event.
  • Funnel Analysis — Funnel reports now allow you to see Engagement Index data.   You can see the Engagement Index for events at each step of the funnel and the Engagement Index for the entire funnel.  This information is viewable by funnel segments.
