Introduction: Many people new to marketing think that Keyword Effectiveness Index (KEI) is the magic formula to achieve high ranking in the search engines and thereby secure a steady stream of money. The claim is supported by the documentation of almost all keyword research tools and has been repeated by thousands of inexperienced marketing people.
I say that if anyone says that the Keyword Effectiveness Index (KEI) is great to find good keywords/search terms, without explaining any of the drawbacks, then they are either out to cheat you or they just don’t know any better.
