Hello, I just read some post here about keyword research.. I just want to know how to use the google keyword tool, Do I need to put check the exact rather than the phrase or broad? What is the acceptable Global Monthly Searches? I know that the CPC must be $1, but is that real CPC? Another thing, do I need to check spyfu for advertiser for that exact keyword? What if there are no advertiser on that exact keyword? Thanks..
