There are far too few tools developed exclusively for affiliate marketers. When you find one (and a good one at that) it's essential you at least try it out for yourself. One such offering I have recently come across is AffMeter, a software solution which offers statistics, analytics and reporting exclusively for affiliate marketers to see this important data from all of the major affiliate networks they participate in. With a 60-day money back guarantee - it's worth a closer look.
One of the challenges of being an affiliate is the actual management of your campaigns as most marketers use multiple affiliate networks. With AffMeter, you can view your earnings from these affiliate networks and their merchants in one place, set up accounts for multiple networks in different channels, find top revenue generating (and losing) merchants, view EPC's and make comparisons between different time periods regarding your revenue generation, and a lot more.
Many of the major affiliate networks are supported currently, including Amazon, AvantLink, Buy.at, CPA Empire, Canadian Sponsors, ClickBank, ClixGalore, CJ, Google Adsense, LinkShare, PepperJam, Performics, and a whole host of others. LinkConnector, Shareasale and Incetaclick will apparently be added in the future.
Another interesting feature is that AffMeter users can also check their Google Adwords PPC campaign costs automatically. As margins become increasingly slim for affiliates using PPC, good tools will be how you ensure profitability.
