Does anyone have any experience using the
SEO MOZ KW difficulty tool? I've used the tool a lot and have seen the difficulty % change dramatically from day to day for the same keywords. (Obviously I know that nothing like this is 100% and is supposed to be used as a guide only).
When you are looking at keywords for a site, if you use the tool, where do you personally draw the line? In other words, what difficulty % do you consider not worth your time?
In my experience, a keyword with the score of 45% takes about 9 months to rank well. So, anything with a 50% or higher, I don't even bother with.
Perhaps someone else uses the tool differently. I'd love to hear your thoughts.
