If  you ask me chitika is the best adsense alternative which i have ever used.You can use it along with adsense to give your website visitors a little bit of variety from what adsense is giving.They look different and you can customize them.

I preferred bigger slots on my 3 websites each earning $5 each day which leads to $15 that too with ease as many times adsense cpm goes up and down but chitika’s remain almost same.I am now happy.

I am now looking to expand and target more on this publisher network.It is good to have options ready otherwise keeping all eggs in basket can be sometimes dangerous.I would love to hear from you.
