I've looked around the forum a bit and didn't really find a verbatim answer to what I was looking for. I'm looking to hear from a few masters here what's their master "check-list" of what identifies something as a good quality Long Tail Keyword in modern SEO. In this question, I am asking in regards to ranking for high paying click Adsense keywords, for when people click on my ads. (What I mean by this is if there is no adsense/cpc value to the keyword than I am not interested in ranking for it) In this question, I am only looking for untapped / non-high competitive keywords. Would anybody be able to produce a "master" list of their "go-to" research items? (I'm not implying the ones below are accurate just a list of examples) Ideal keyword should be minimum $1 in Google Keyword tool Ideal keyword to have < 80,000 searches in google The ideal keyword should have had a.) no wikipedia link on front page, b.) YouTube video on front page. Ideal keyword should have no stop words Ideal keyword should have low competition rating in Google Keyword Tool This post is not asking "how" to find long tail keywords but rather all the combination of information & identifiers that make it a high paying keyword I appreciate any responses and thank you for your time.
