Ok I have a question: I have 2 different keywords say "super motor boats usa" vs "super motor boats alaska" the one with usa has 110 avg searches a month but .93 competition. the one with alaska has 20 avg searches a month but .77 competition. I can only choose 1 as the target keyword for my title tag for example. is there a unit or scale to combine both search volume and competition to choose which one? do i use my gut feeling? is there a more logical way to choose from the two as a target keyword?
