There are a lot of money to make the search engine traffic, but we need to know the right keywords for us to get our share of the money.
Almost every keyword tool has the same features and almost all of them use google to search a database of profitable keywords. A successful search engine marketer and non-successful people may have the same tools, but it's not a tool that makes a user successfully. It is still the user.
I decided to write this article because I received many emails about keyword research and a lot of people ask my opinion about their keywords, why do they have a higher ranking but no traffic and other stuff like that.
