How to make keyword research?

Answer on question: "how to make keyword research" is by using KEI and KOI. Let's start with KEI.

Keyword Effectiveness Index (KEI) - helps point out which keywords are the most effective and valuable. The KEI compares the number of monthly searches for a keyword with the number of search results and help to find the most effective keywords.

To find KEI use KEI formula:

KEI = (Number of Monthly Keyword Searches)^2 / (Competing Pages)

Number of Monthly Keyword Searches - this indicator you can find using Google AdWords Keyword Tool.
Competing Pages - find using Google search. Just enter your search term and check number of results.

To make things more clear take a look at this example:


• we want to make keyword research on this keyword combination: "google keyword research"


• on Google AdWords Keyword Tool page we can determine the number of global monthly searches for specific term, for keywords term "google keyword research" it is 9,900 searches per month
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
• to find out raw google competition for specific keywords term we use Google search. For "google keyword research" there are 15,200,000 results.
  
  
  
  
  
  
  
  
  
• now we can calculate KEI
  KEI = 9,900 ^ 2 / 15,200,000
  KEI = 6,49


• higher KEI better keywords combination. With KEI we try to find keywords which are highly searched but in the same time are not overused on web

There is one more indicator similar to KEI - Keyword Opportunity Index (KOI). KOI compares the number of monthly searches for a keyword with the number of directly competing search results.

Formula for KOI is:

KOI = (Number of Monthly Keyword Searches)^2 / (Directly Competing Pages)

Example for calculating KOI for keywords term "google keyword research":


• monthly searches for keywords term "google keyword research" is 9,900


• number of directly competing pages can be found by using Google operator "allinanchor:". This Google operator return results containing query terms specified in the anchor text on links to the page.


• number of directly competing pages for "google keyword research" is 9,740,000.
  
  
  
  
  
  
  
  
• KOI is:
  KOI = 9,900 ^ 2 / 9,740,000
  KOI = 10,06

When you ask yourself how to do keyword research, it is good practice to find various keywords combination (thesaurus synonyms can help) find KEI and KOI for each of them and compare. Keywords combination with highest KEI or KOI is best choice. KEI method doesn't measure quality of competition just quantity (number of search results). To get quality in calculate, you can use SeoQuake, it show Google Page Rank for each result. So, if first few results have high PageRank, quality of competition is high.
