How to Choose the Right Keyword Using Keyword Effectiveness Index Formula (KEI)

One way to analyze a keyword competition is using is KEI or Keyword Effectiveness Formula. This is a simple formula to give you an overview of the competition using the data gathered from Google Keyword Tool and Google Search Engine.

Here’s the formula:

KEI = gsr /gsc

gsc = Google Search Count

gsr = Google Search Result

Google Search Count is derived from Google Keyword Tool. Just type in your keyword and get the value of Approx Avg. Search Volume. This is the estimated searches made for that particular keyword.

While, Google Search Result is derived from www.google.com website. Search your keyword and get the number of the search results at the upper right hand corner.

The higher the KEI the better it is to target.

For example, if you’re building a website that’s about “dog training”, you can search Google Keyword Tool and Google.com website to get the following values:

Keyword Google Search Count Google Search Results KEI
dog obedience training 60,500 3,330,000 0.018168168
dog training tricks 2,400 374,000 0.006417112
dog agility training 14,800 2,880,000 0.005138889

With these results “dog obedience training” is a better candidate

Though Keyword Effectiveness Index Formula is a good way to measure the competition, this is not the end all be all. This should be accompanied by other analysis like using Google operator (e.g. allintitle, allinurl, etc.), unique selling proposition, website authority, and other ways to identify the quality of competing websites.

    Hi,
    i am sujeet nad your formula is wrong
    KEI = gsr /gsc

    gsc = 60,500

    gsr = 3,330,000

    KEI = gsr /gsc
    KEI=3,330,000/60500
    =55.0413223
