i want to estabalish an ebusiness , so want your opinion as i am suggested to start a pay per cick campaign google adwords for promotion , a few also said ypn , now which one should i choose if any ????
YPN is an equal in terms of service to AdSense. I think what you are trying to compare is AdWords and Yahoo Search Marketing. I've tried AdWords and it's faired well and I've also tried Yahoo, all I can say is that I got similar results in terms of traffic being generated.
Personally I prefer Google AdWords over YSM (not Yahoo Publisher Network) but for starters YPN is probably a little easier to use.
For a beginner i say YSM but if you wan more traffic go with Google, it also depends on the niche you are going after and the budget.
Try with Google Adwords., it is a authentic way to brand anything ONLINE... and at reasonable price also.. YPN is a bit expensive and good for US traffic
