1- The earnings are much lower than adsense. 2- Good supplement to use with adsense. 3- It analyzes your pages and creates links on certain terms to their ads. 4- Some pages come out nicely with just a few links. Some end up with waaayyyyy too many links to their ads. 5- easy to apply for and they will accept almost anyone. 6- It doesn't work like adsense where you just get the account and place ads on any site you want to. You have to get permission for each site you want to place ads on. 7- Some people complain that it drops overall earnings since they get less adsense clicks with kontera on a page along with adsense. If you keep the adsense above the fold, and kontera within the content (of course), this shouldn't really be an issue. Good luck!
thank you. more question.. can I use google and kontera together? no the same site but to use with them.. sorry about my language =/
