The KEI compares the number of searches for a keyword with the number of search results to pinpoint which keywords are most effective for your campaign.

Suppose the number of searches for a keyword is 486 per month and Google displays 214,234 results for that keyword. Then the ratio between the popularity and competitiveness for that keyword is 486 divided by 214,234. In this case, the KEI 0.002.

The higher the KEI, the more popular your keywords are, and the less competition they have. That means that you might have a better chance of getting to the top........     

Some time ago my friend also asked my about it, but I didn't have no idea about KEI key,  Its really a very nice information.

KEI is the vital term when calculating the value of keyword phrases to target for your blogs, websites. It is simply an indicator of how popular a search phrase and how competitive the market for this search phrase. The formula simply stated as (Number of monthly searches) squared divided by (Competing Pages). It is a simple mathematical equation, but tells a lot about the keyword competition for SEO experts, online marketers and surely for bloggers.

KEI:- Keyword Effectiveness Index is a measure of how effective a keyword is for your web site.Three axioms are the basement of the KEI :

* The KEI of a keyword should decrease if the number of competitors increases.

* The KEI increases if the number of searches increases. If a search term becomes more popular and the competition is stable or growth slowly, you have a more competitive term.

* When simultaneously a keyword becomes more popular and more competitive and the ratio between popularity and competitiveness remains identical, its KEI should increase.
