I'm trying to put in place a system which selects Longtails which will be easier to rank for. Of course, the system is automated and scrapes data from Google Search and Google Keyword tool... but I'm not sure what factor should get more importance. I dont want to ever look thru the Keyword list manually... so there should be a reliable underlying selection criteria. There are 4 kinds of Keyword parameters that I'm scraping and want to use... 1. Hits, without quotes 2. Hits, with quotes 3. Intitle, with quotes 4. Monthly Search volume But some Longtails have a huge difference between normal and quoted Hits. For ex. online mortgage brokers 13 mil hits "online mortgage brokers" 30K hits intitle:"online mortgage brokers" 76 hits only Monthly Search Volume 540 From the above, we see that the last 3 factors clearly say the Keyphrase is a usable Longtail. But the Hits for unquoted search are over 13 million. So, should we ignore the unquoted-search factor altogether? What factors do you guys use in selecting Longtails and do you use some kind of Weighting formula for the parameters involved?
