They just like any other affiliate network; they no better no worse that the others. I joined them as they had an advertiser relevant to my niche. BTW - shouldn't you have posted this in the affiliate forum (where there are similar questions been asked) and not the Adsense forum.
I checked them and found their commission percentage is very low like any other tangible products. Clickbank commission % is high because they offer only digital product.
Never knew about a Google affiliate network. Is this global in regards to the merchants and do they have some big names on board?
Google purchased the Performics network a while back; it global; its just another affiliate network, typical of all the others. http://www.google.com/ads/affiliatenetwork/
they suck big time, i think half my leads didnt went through, and they are like super active against fraud i think i had generated $100+ leads and all got rejected so i h8 them big time
Have applied anyway. Hopefully they run an affiliate referral program, I reckon many bloggers would signup to that.
