I`m using adsense and some other company in my country , i got premium ads that pays 20-30 cent per click there , so adsense isnt the best always , depends on your site.
What are good affiliate network? I heard thats hard to make cash, because people seldom order thru the advertised link. My friend said he tried affiliate advertising but no one ordered from them.
I read a newyork times article where it stated Google payed up to 70% of the click to the website serving the ads. That is a good percentage.
I am using infolinks.com . It is an inline Text advertisement program and CPC. It pays me more than Adsense. But still Adsense is one of the best among CPC Advertising Programs available.
