I am trying to rank some keywords and I use a tool called kwfinder. I look for keywords with low SEO competition. Meaning that the people ranking for the keywords presently have low PR, TF and CF. If they are very look I figured it would be easier to rank those keywords. Is this the way to go about it? Some keywords the competitor ranking high for them have a TF and CF of in the high 40's and page ranks of like 4 and above and I figure to jump ahead of those established sites would be very hard. Am I going about this the right way?
