“It is interesting that we do not see much written on affiliate marketing analytics, whereas if there is one industry that relies on analytical data especially heavily it is affiliate marketing” — this is how my newest article starts. It is one of the feature articles in the Summer 2010 issue of the Visibility Magazine.
In the article I look at 3 basic KPIs for affiliates/publishers (EPC, Conversion Rate, Reversal Rate), and 5 key performance indicators that merchants/advertisers should be measuring and analyzing on an ongoing basis (Affiliate Recruited, Activity Index, Activation, Traffic, and Transaction Volume). Visual examples of data presentation on three different affiliate networks (AvantLink, ShareASale, and Commission Junction) are also provided.
The article is coming out in the print version of the magazine, but you may also read it in the digital edition here (on pages 38-39).
