In order to know which keywords to optimize for on the search engines, it is extremely important for me to know how often actual potential clients are entering the keywords I'm thinking of optimizing for. How do I discover that?
I tried word trac ker dotcom, but its results were unsatisfactory to me. I felt that its results seemed somewhat skewed, and did not give a true picture of what is going on out there.
So can someone suggest other keyword popularity tools or ways of figuring out which are the keywords I should be optimizing for? (Someone told me about Overture keyword selector tool.) I would appreciate hearing not only which tools are out there, but how reliable or useful you have found them.
