the 68 cents was pretty much all from the eCPM. I got nothing from the 4 clicks.. 1.243 X $0.55 = $0.68
ecpm is not what you think, they do not pay in a cpm system, this is just an estimation. You can go either for a cpm company or switch to google image ads.
oh so for example when it says my eCPM is .50 that doesnt mean i will get 50 cents for every 1000 page impressions?!
To echo a few of the comments that have been posted, you really do need to remove those images as you are committing a breach of TOS by showing that much information about your stats.
What type of forum is it and do the banners relate to the forum? For example if you own a dog forum and you place "dog training" banners on the forum ,im sure there would be a lot of clicks.
Forums are notorious for their low CTR, but yours is below average. I had a 1-2% CTR usually on my old one. It's best to place your ads under the nav bar, under the first post, and after the last post.
I just made a post in my blog about Kontera earning more than Adsense. You should check it out.. basically, for a content-heavy site like a forum, Kontera can earn nearly as much and sometimes more than Adsense. You might want to give it a try.
so tru. i just started kontera last week also and im already earning slightly more with them than i would with adsense. for instance i earned a little over $10 with adsense yesterday compared to 18 with kontera. another thing ,.. have you tried selling adspace .
