KOI – Keyword Opportunity Index

So how does this equation work?

Well, first of all, for this equation, there are two figures that we need to calculate, the number of people directly competing for it and the number of searches per month. From these two figures, we can begin to build our Keyword Opportunity Index (KOI) equation and determine which keywords are likely to be successful.

Compete directly

We can solve this by going to Google and typing in allinanchor: keyword example. This will tell us in the upper right corner how many people have links that anchor the phrase we are optimizing for.

Monthly searches

This is the number of people searching for the keyword per month; You can find out by using the Google AdWords keyword tool. This will give you the number of times the phrase is searched on average per month.

The KOI equation

Monthly Search Number x Monthly Search Number / Direct Competing Number = KOI

So for example, if the monthly search figure was 201,000 and the directly competitive figure was 40,500,000, we will square the monthly search figure (201,000 x 201,000), giving us 40,401,000 , 000, so we need to divide this by the amount of direct competition by what 40, 401,000, 000/40, 500, 000 which gives us our KOI which is 997.555556.

The idea behind this is that the higher the KOI, the better the keyword.

Why use KOI?

KOI offers a measurable scale, which takes into account the popularity of keywords and the competition around them. Taking these figures into account, you can choose keywords, which are very popular but have little competition. It offers you the opportunity that you have a successful keyword.
