How is KEI Calculated?

KEI is calculated using two factors.

1. Number of searches made for a particular keyword
2. Number of competitor pages for that keyword

The formula for calculating KEI is = (volume of searches per day)^2/(total number of competitors)

For example, the keyword phrase "real estate", has a daily search volume of 11,039 (as per Wordtracker) and 490,000,000 competing web pages*. Using the KEI formula, the KEI for "real estate" is (11,039)^2/(490,000,000) = 0.25. Ideally, you want keywords with a KEI greater than 1.00.

A better keyword phrase would be "real estate property listings". Taking the daily search volume of 3,056 and the number of competing web pages of 305,000, the KEI would be (3,056)^2/(305,000) = 30.62. Excellent KEI!


* To obtain the number of competing web pages, go to Google.com and search your keyword phrase with quotation marks (i.e., "real estate").
