What Is KEI (Keyword Effetiveness Index)

KEI is Keyword Effectiveness Index. KEI measures the number of searches for a keyword with the number of search results to point out which keywords are more effective and fruitful for your business. 
Suppose the number of searches for a keyword is 500 per month and Google displays 500,000 results for that keyword. Then the ratio between the popularity and competitiveness for that keyword is 500 divided by 500,000. In this case, the KEI 0.001. The higher is the KEI, the more popular your keywords are and less is the  competition. This gives you a fair chance for you to be on top with that keyword. 
However, the KEI makes no statement about the quality of the competition. While there might be only a few competitors in the search results, these competitors could be big players with big SEO teams and thousands of back links.
But do not panic if you don't have a better KEI. You can get on top with any keyword of your choice provided you put a lots of wise effort in your work. Yes wise Effort, mind it. Play with the search engines by following the basics of search engine techniques. And definitely you are gonna rock with your keywords in no time.
