Facebook Permission Dialog Performance

In the last post, I mentioned that I had received a bit of feedback from users of Relevenz that were reluctant to use Facebook to sign in. This results in a number of bounces from the site.


There is another metric which you should check if you are using Facebook to sign in to your web application - the performance of the Permission Dialogs.


If you have ever used an application in Facebook or used Facebook to sign in to a site, you have to grant a set of permissions to that application so it can access your profile. The dialogs that Facebook shows to grant or deny permissions are called Permission Dialogs. 


You can find out what proportion of your users that grant or deny permission to your application by looking at the performance of these Permission Dialogs. Simply check the "Users" section of your application's Insights page. At the bottom of this page, you will see the number of Permission Dialog Impressions and Permission Dialogs Accepted.


The percentage conversion is a very important metric to add to the number of installs. It will give you a much clearer indication of how well your application is being adopted.
