I heard an news from chitika, the YPN! closed, and yahoo transfer their client to chitika.
I had reported that chitika is the best online blog advertising network, this news proved my views.
In the current I have 2 sites approved by the chitika union,they earn xx$ per month for me, because I just show this AD for US visitor by a GEO AD plugin write by myself. I heard now chitika will support EU traffic, I’d like do a test, maybe my revenue will have a big improve, because many of my reader come from UK.

Chitika is a online advertising network which offer ads service for 80,000 sites, in last years, chitika offer CPA ads(founded in 2003),  but it have CPC ads now.

Chitika said their CPC ads will only support USA and CA traffic in the current , but you can specify another ad code(adsense,cj…  and so on )  in the admin area of your account,  so when a England user viewing your site, you can get profit yet.

Chitika have CPA and CPM ads too , you can choice which kind of plan is the best on your site. What you need to do is just copy code and paste on your site, it is very easy to make money from this ad network.
