Google offers a Keyword application that allows me to see the number of time a particular query has been made in Google.
There is a column in the results named "Competition" (Actually its Concurrence in French, I'm just translating). Its a rating from 0 to 1, as in percentage. What indicator is that?
Is this something useful I should rely on? I'm not sure about how to interpret this data. Should I go for less competitive keywords with a lower number of searches or not worry about it and go for the highly searched keywords anyway? Is 50% considered high? what about 75% ?
I have a very niche market that sell expensive offline services, so the very long tail is my goal (I assume). If you didn't already figured out, I'm very new to SEO =)
