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
