The Definition and Formula of KEI
KEI (Keyword Effectiveness Index) is a proposed standard formula to calculate how competitive and popular a set of keywords in
search engines. KEI for a keyword phrase is formulated as ;
KEI = (Number of Monthly Keyword Searches)^2 / (Competing Pages)
Competition
Before explaining why we had the square of searches the formula, we should think ourselves how we basical y find the competition
and popularity. In SEO world, competition is the number of SERPs (Search Engine Result Pages) for an exact keyword phrase. If I
open Google and type the exact phrase using double quotes "iphone games", currently I get 1,400,000 results. It is the number of
pages we should beat in competition to be ranked in first page results.
Popularity

---

We can find the popularity of a keyword phrase using free tools like Google Adwords Keyword tool or paid tools like Wordtracker. I
prefer to use Google Adwords Keyword tool. It is quite useful and returns relevant up-to-date results.
According to Keyword Tool, there are approx. 140,000 monthly worldwide searches for "iphone games"
We could simply divide these numbers and compare the result with the results of other keywords, but KEI didn't do like this. There is
a logical reason for this.
Explanation of KEI Formula
Suppose that we have another iPhone related keyword with monthly searches of 5 and with 50 competing pages. It means that it wil
be easy to rank at the first place, but it doesn't worth the efforts since there is no demand !
If we simply divide both numbers for both "iphone games" and "our keyword" we would end up with the same result. 1/10. It is
certainly apparent that they don't have the same value.
If we would just look at this simple division result, we could be deceived. Because of this, KEI squares the number of searches as a
signal to show its popularity.
Actually, you could just use any other power. For example I can write the formula as Power of 3.

KEI = (Number of Monthly Keyword Searches)^3 / (Competing Pages)
But this time, since I have given more importance to popularity (number of monthly searches) I have to give much more efforts to
rank better in SERPs. This number depends on SEO skills. I personal y use power of 2 as a proposed standard.
Usage in SEO
Actually, it is a systematic and straightforward approach. For example, if you have determined that lets say, Palm Pre related
keywords are getting high KEI, you should begin writing articles using the exact phrase in the title of your article and one, two times
inside the article text. Do not forget to add a few tags without spamming as well. Then, you should hunt for dofol ow backlinks to
increase your position in the eyes of search engines. Submitting the article on social networks with dofollow and finding blogs with
dofollow comment mechanisms like Comment Luv is not an hard task, but can be time consuming.
