In 2009 Website Magazine came out with a Top 50 list of Affiliate Networks that ranged from CPA (Cost Per Action) to PPS (Pay Per Sale) and PPL (Pay Per Lead) networks. In 2011, they came out with a new list of Top 100 Advertising and Affiliate Networks (which was actually only 99 if you count them). What I find interesting is the new blend of Ad Buy Search Networks vs the Affiliate Marketing Networks and the differences between them. You can read the full article here for more information about these. More Ad Networks, such as 7Search.com are popping up as well as more CPA. I also find that most networks are looking to offer additional services to be more E-Commerce 3.0 friendly. Ultimately networks are continuously looking for new ways to increase their revenues and service offering in this highly competitive industry.
Here is a recap of the lists from 2009 and 2011.
Top 50 Best Affiliate Networks in 2009
Top 50 Advertising and Affiliate Networks To Consider in 2011
49 More Advertising and Affiliate Networks to Consider in 2011
What I find interesting is that no affiliate network or ad network made it into the top 5 both years. Even ShareaSale dropped for #9 in 2009 to #41 in 2011, ranking far below many other newer affiliate networks Ive never even heard of before. It makes me wonder what rating criteria they are using to select their rankings and how they are assessing the quality and value of each of these networks to determine who deserves the #1 spot. Either way, you can see there are a great variety of affiliate networks and ad networks to choose from. I recommend shopping around to find the one that best suites your needs while also taking into consideration their reach, ethics, affiliate base, cost, tracking technology, back-end platform and overall reputation in the industry from people who've actually used them.
