If you already use ActionKit reports and analytics, you may be interested in using ShareProgress to find out which supporters were brought in by ShareProgress sharing tools.
ShareProgress integrates with ActionKit's action source codes and can automatically add these these codes to every page you create.
First, visit your account settings page. Under Advanced Settings find the option labeled "Customize URL share source tracking parameters" and check that box.
Set the URL source parameter name to
source. You can also change the other parameters to anything you would like to label users as.
This will attach source codes for any users who are referred through a ShareProgress action within your database on the core_action table. If the user is new, you can find their source on the core_user table.
Whether you take these steps or not, you can always still enjoy all of ShareProgress' analytics to find out how many people are being brought in from social sharing.
