Hi people, It feels wonderful to be back after a sabbatical. As usual I have a query and I need you guys to help me with it. I have a query pertaining to keyword discovery. I have a presentation coming up and I need to train some people for the same. Can someone help me with it? I just have a basic understanding of keyword discovery. Is it a paid keyword research tool? Is it the most extensive keyword search database? What are its important features? What about its advantages and disadvantages? Can someone enlighten me on this? Thanks.
