I'm using the keyword difficultly tool to help me create a a list of 5 keywords (out of approx 50-60) to optimise pages for on a site. However I don't want to just choose the top 5 if 3 of them are too competitive and not worth targeting.
From anyone's experience, for a small, new web company who has no pages optimised at this point, do you think there is a keyword difficulty score that I should create a hard limit on?
So for instance, with a group of keywords, to only target keywords that have a difficulty score of 60 or below because anything higher would be too difficult to optimise the pages for in this stage of the sites development.
Thanks in advance for your help
