I'm doing intense keyword research, and wondering how long-tail is too long-tail. I'm at over 25,000 keywords now for a single niche from every possible source. How do you decide which keywords to use? 4 words? 5 words? 10 searches a day? 1 search a day?
Is every keyword worth pursuing, or do you stop at a reasonable limit of popularity?
