What is the KEI (Keyword Effectiveness Index)?

What is the KEI (Keyword Effectiveness Index)?

The KEI compares the number of searches for a keyword/phrase with the number of search results to pinpoint which keywords/phrases are most effective to target.

Suppose the number of searches for a keyword/phrase is 250 per month and Google displays 100,000 results for that keyword. Then the ratio between the popularity and competitiveness for that keyword is 250 divided by 100,000. In this case, the KEI 0.0025.

The higher the KEI, the less competition they have. That means that you might have a better chance of appearing in the top of search engine listings.

Is there a minimum value of KEI to shoot for?

Not an easy question to answer.  Yes and No, it depends on the total number of results.  You should have a max number of competitors to be competing with.  If you are competing with millions, the chances of coming to the top of the list are slim.  For keywords or phrases I try not to target results with more than 1000 competitors.  There are better chances of organic results that will pay off.
