UTM parameters are automatically added to all stories in any 'gallery' built on the Friend2Friend Platform, when those stories click to other sites or locations, such as the original source of a story on Instagram, or the location of a piece of community content on Jive Software.
Using UTM parameters means that you are able to track activity based on those parameters. The parameters are:
utm_source = f2f
utm_campaign = the f2f app id (this changes from one gallery to another)
utm_medium = link_click (this changes depending on where the user clicked)
