Not recommended. I used clicksor on one of my sites but did not stick around long enough to collect any earnings from them.
Back when I signed up with them (about a year ago), Clicksor was not a truly contextually targeted PPC program...you basically give them some keywords that describe your site, and they try to deliver ads relevant to your content. Perhaps their ad delivery technology has changed. Does anyone know?
Clicksor pay affiliates twice a month on time,but they would deducted part of your earnings daily. Due to they consider that part of your clicks were incentive clicks. That's made me not feel very good.
2. 99% of the time the ads have absolutely nothing to do with your site content.
3. They are only too willing to allow spyware sellers to advertise on thei network.
several times I have had to send them stern emails complaining about spyware sites hijacking my site and forcing my visitors to go to their site where spyware will be installed with or without their permission.
I currently use Adbrite who seem to have a better pay rate.
