To monetize your site there are a few good alternatives. As I mentioned before very popular are Google Adsense and Yahoo Publisher Network, but there are a few others that are pretty good for making money.

let’s see them:

AuctionAds.com - This is a newcomer in this, but its really really working great. Just give it a try. Account is instantly approved.

Adbrite.com - Adbrite is your second best adsense alternative to monetize your website. Please note, you may see very little earnings for first days as they collect your website statistics.

Clicksor.com - Clicksor is third best adsense alternative. It provides both inline and text-banner contextual ads for your website. So it can also be a good alternative for google adsense.

Kontera.com - Kontera is an another option which provides inline contextual ads.

Text-Link-Ads.com - If your site is atleast PR4 or have good alexa then you can earn quite a good amount by selling directory links through ‘text link ads’. If your page rank is higer, it can ever surpass your adsense earnings. So go for it. It is highly recommended.

Chitika.com - Chitika created a lot of noise when it was started as a google adsense alternative. But finally it has stabilized and is a contant good earner.

Bidvertiser.com - Bidvertiser is also a good contextual ad option for your site. They have been paying from a long time and are quite consistent.

Etology.com - Etology is a new adsenes alternative and is told to be doing great. Some of the publishers claimed that they are making double with Etology than with Adbrite.

There are other programs which I hightly recommend. These are not the adsense alternatives but can surely complement your revenue with very good payment.

CasaleMedia.com - Casale media is one of the best banner advertising network providing one of the best eCPM for your ad space. They provide 728×90, 120×600, 300×250 banners and popups. They payment rates are really really good.

Adversal.com - Adversal is popup program which pays a huge $6.00 per 1000 unique impressions ($6 CPM).
