Ive had Kontera less than a month and had a few clicks on it, its helping to increase my earnings overall - but for the amount of click i get its shocking. I run it on a few sites, with adsense i would get on average between $0.50-$1 per click (on average sometimes lower sometimes higher) With Kontera im getting around $0.10 MAX. Usually its around $0.07. Ok its an extra source of revenue and it hasnt reduced my adsense significantly but it also hasnt increased my income by anything more than $10 a month. Personally i dont think i will bother introducing it on any of my new sites its not wrth the time
Kontera varies alot. I've heard of 0,20 cent clicks, but i also always had 0,03 cent clicks or less only. that may be due to the niche i am in though. i had it added on some forums and even then it wasnt worth it. I got better paying clicks due to the variety of content, but it annoyed the heck out of some members and even me. i still use them on content heavy sub pages though as some sort of extra extra income lol, means i dont care about the revenue i make with them.
i think i got more money in pocket money when i was a kid than i do from kontera. I dont know what all the hype was about. I think they need to sort out what they pay people once i get to the threshold it coming off all of my sites (although that may take a while ) All i would say to people is dont waste your time, you need a huge site to earn as much as adsense does on a small site
