Clicksor

Clicksor is the third most popular alternative of adsense.It is pretty good to be honest but due to restrictions of something like 5000 page views per day makes it rank 3rd.Their tolerance level is also better than most of the ads companies around.Lets discuss some of its features
Benefits:

• A really big range of ads types available

1. Pop unders
2. Animated Ads
3. Image Ads
4. Text Ads
5. Flash Ads
6. Banners
7. Interstitial Ads
8. Dynamic Ads

• The minimum pay out from pay pal is 20$ and 50$ from check.It is not really bad.
• The pay period is the fastest of all ads agencies,15 days only.
• They are highly contextual.That means they totally shows only ads that matches your keywords.
• They have a real time costumer support which is really exciting.
• The statistics are real time too and gives a handy set of information frequently.
• They have 3 types of payment on ads service.Cost Per Click, Cost Per Visit and Cost Per Thousand Impression.The ads either of these 3 will be selected through the wish of the publisher which is another impressive feature.

Concerns:

• The restriction of 5000page views daily is quite a headache for smaller bloggers or websites.
• The ads take really too long to show that does not impress the visitor and hence results in moving to another destination.
• Only English Ads are accepted

I haven't tried clicksor ads myself yet I am showing a screen shot of earning of one of my friends.But, the feed back from other guys and friends is quite good.But, just a piece of advice, you should have a good amount of daily traffic to your website or blog if you are looking to go for clicksor.So I would rate it high for bigger guns and pretty low for the small bloggers.
