I had a list of about 25,000 keywords and I limited it to about 6,500 by running it through AdWords keyword tool, and then to about 1,500 by chosing the ones that are most interesting and stay, for the most part, in the range of 1,000 to 5,000 Local Monthly Searches (on [Exact], USA only).
I have that list in a spreadsheet and I am wondering what would be the best way to determine which keywords are the best candidates for SEO websites from the perspective of competitive research.
Somebody told me that I can enter keywords and add all the Page Rank numbers on the first page, and if the number is less than 20, I should be able to beat the competition, but from what I've been looking I am not sure how good this method really is...
I also have #*$! installed on Chrome and it shows all the information like PR, Google Index (number of indexed pages), Bing Index, LD (#*$! linkdomain), and some other info like Alexa Rank, domain age etc. I also have 3 SEO plugins for Firefox that show similar information.
Having all that info I am wondering what would be the best way to find good candidates for website building out of these 1,500 keywords. Would I be looking at backlings number only, or Page Rank method etc... If the number of backlinks is what matters most, what would be the best source of that info and what would be a number that I would be looking at etc (I know there more to it than this <like link anchor text, reputation of sites when the links are coming from etc> but I am just wondering about the best and fairly quick way to get some good keywords out of the list that I have)
