How much is your max cpc? i found it is difficult to set a good price in keywords Usually you will not get any traffic if price is less than $0.1 I am trying to find some cheap keywords,but what i find is that all keywords with traffic is high. Is there anybody who can list some cheap keywords with traffic?
No offense, but it's called research- do it. Besides, you are apparently looking for something for free- of course any keywords with traffic are going to be priced high, that's how it works.
Plus, how much of an idiot would you have to be to tell someone else what your good, cheap keywords are, so that they can compete against you. Let alone post it on a forum so any Tom, Dick or Harry who doesn't even have a log-in can join in too. But actually Adwords pricing is much more complex - I could - but won't - tell you the keyword that I pay 4p for that gets me most of my traffic - but I can also guarantee that you would have to pay a lot more, because you don't have a site optimised for that keyword, that's a top site in that niche.
