Never argue with the data
There are many tools out there to find long tail phrases… Duh… Long tail is very popular now. But have you ever wondered if the long tail popularity has actually been self fueled to a certain degree. As people try to make up long tail phrases, do they actually pollute the data? Do some tools show a phrases simply because a marketer tried to research it?
Personally if I see that a particular phrase only has a couple searches a day, I don’t get to excited about the phrase. If I see a hundred searches a day with less than 100 matching results in google, that is more interesting.
What would be interesting to see though is a source of data from before long tail became popular. While it might not have data about things that are very popular today it would contain still a wealth of data that could be very useful for find phrases for many subjects.
That being said, I got some data from several years ago that I am analyzing and hope to being to the site in the not too distant future.
