i have heard that google pays us based on CPC as well as CPM. so it depends on the advertiser on which ground( CPC or CPM) he wants to display his ads. so i tried to open an adwords account but in that it only asked me about the CPC rate, not about the CPM rate.. can somebody answer on this
You need to make use of site targeting. You choose a specific site to advertise on and it should allow you to choose eithr CPM or CPC advertising. I'm not an AdWords advertiser though, so I'm taking a guess here.
not satisfied with your answer.. i was just opening an adword account..and it asks only how much you want to pay for CPC for particular keywords and daily budget.. it never ask for CPM
Did you try site specific advertising? CPM advertising is only available for site specific advertising. Try reading through this or the more comprehensive AdWords help files. As I said, I'm not an AdWords advertiser so I can't help you more than pointing in the righ direction. You'll have to read the help files and find the answer yourself.
