I have been a Kontera publisher since last Summer, at first they refused my application becuse my websites did not have enough traffic for their requirements but I persisted and was finally accepted. This week I got my first paycheck from Kontera, because it took that long to accumulate $100 in advertising revenue. This is a very low clickthrough rate and low CPM rates. Compare that to my Adsense income and Google is paying about ten time more than Kontera. I am going to check all my Kontera optimisation when I get some time, but I have to ask myself whether it is worthwhile continuing to display Kontera ads. Merrell shoes
