Ok.. now what is KEI? hmm.. the simple explanation is the efficiency of a keywords… the higher the better…
KEI is a formula or mathematics calculation KEI = Search Volume (squared) / # of Competitors
For more clearly what the mean of Search engine volume and number of competitors let’s we look more deeply:
1. SV (search volume) = is the approximate number of search these keywords in 1 month. For example in case you want to search for SV from keyword “free money” …
The first step is to go to http://freekeywords.wordtracker.com, and type in “free money“, then you will get results which is approximately 1741 for “free money” keywords. This means there is a 1741 search everyday for the keywords “free money“. This also meant 1741 X 30.5 = 53,100 per month (approximately monthly count). So this 53,100 digits number is the SV (search volume) for keyword “free money.”
2. # Of Competitors = number of the web that contain keywords that we wish to find her KEI. Here the easy way… you open http://www.google.com, then type the keyword “free money”. After that you could see result in this part: “Results 1 – 10 of about 187,000,000 search results for free money. (0:24 seconds)“… So the number 187,000,000 # is the competitors for the keywords “free money.”
Well so we got all the recipes for calculating the KEI… Now we just enter it into the formula:
And we got the result is 156.6
Well now you’ve know how to calculate the KEI (Keyword Efficiency Index). Now apply the above ways to your entire list of keywords that you have listed in your excel file before. The better you know to operate ms-excel is the easier to make his formula in excel.
Here the most important: take the highest 4-7 of KEI as a main keyword, take 20-30 it follows as a variation, related keyword or secondary keyword… Now u got your self list of keyword that you want for your website optimization.
