Here are two ad networks that I have used successfully as Google Adsense alternatives. However, the best thing about the changes to Google Adsense’s TOS, you can now use both of these following ‘alternatives’ at the same time as Google Adsense. Remember, You can use any Ad network along side Adsense – once there is a clear difference between the two ad units. Your users should be able to clearly differentiate the two, and the best and safest way to do this is by changing colors and sizes.
Adbrite
Adbrite is one of the first ad services I used in place of Adsense. It has very similar CTR, eCPM, and Payout in my niches. One of its main benefits for beginner webmasters is that they have much more relaxed terms of services. Its easier for smaller sites or blogs to get approved and start monetizing their traffic – no matter how small. They do not have as many ad formats as Adsense but they do have the most common ones. After you add their HTML code snippet your page it can take a day or two before actual are serving relevant ads. If you can get over those minor inconveniences than it is definately worth checking out.
You share the revenue with the network, you get to keep 75% of all earnings.
Smowtion
I’ve recently learned about this international ad network called Smowtion. Some of the benefits are that these ads are great looking and have much higher CTR than my Adsense ads. The payouts were slightly lower Adsense, but as a secondary network it is great. Normally you only get to keep 60% of your earnings, but if you use this link you will get 80%. Since it is a relatively new network that is base offshores, many people are worried if it is legit or a scam. I can tell you from personal experience that they do pay.
