Looking to create an official list of all the secondary search engines and networks that you can buy PPC from. I will start with a couple. Then....if someone can rank them their favorites first that would help everyone. Abrite.com clicksor.com 7search.com bidvertiser.com chitika.com peakclick.com What else are we missing?
isnt the secondary something from yahoo and msn seach? all 3 are first tier. Others are just side food. It's a mistery to me how they make living.
I've heard many of these secondary engines are even more fraud riddled than the major PPC engines. Has anyone compared conversion results in these engines - that would be helpful. Here is one article that scares me a bit: http:// please remove this space seekingalpha.com/article/36702-is-marchex-encouraging-click-fraud This article is a bit dated, but for me it's enough to test these mediums with my eyes (analytics) wide open.
For my opinion the best two are Search123 and Ask ... My cost is lower and ROI better Google is best if you are doing local advertising All the Best
