Greeting. After reading Contextual Ads System : Earning Beyond Adsense article from Joel Comm(adsense guru for those who didn’t know), i have had install it on this blog. Bear in mind, do not put kontera together with adsense, since it was same contexual style advertising.

You can get kontera for wordpress plugin from this URL here . Just follow the instruction, and in 5 minutes, you are done.

You will notice some words are highlighted and underlined, when you hover your mouse over there, you will see small windows popped out, there you go, kontera ads.
Try it yourself. I’m not sure if the income is great, but at least you have an alternatives to adsense, in case your adsense account banned, you will still be able to monetize your website/blog using this way

Update

Thanks to Scott who pointing out this to me. Kontera now can be used together on the same page with Google adsense
