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 500 per month and Google displays 214,245 results for that keyword. Then the ratio between the popularity and competitiveness for that keyword is 500 divided by 214,245. 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.
Thanks and Regards,
