Keyword Effectiveness Index (Keyword Performance Index KEI) – keyword score, expressed in numerical value, giving an idea of ​​its effectiveness, in terms of search promotion.

One of the key issues of SEO optimization is the issue of evaluating competitors.. I always thought that the effectiveness of a keyword depends on how often it is typed and how many pages users find for this query.. For the first time, the keyword index was proposed by Samantha Roy, who is also its author.. Classic Calculation Formula IT IS = P^2 / C where P (popularity) - the number of requests for this keyword (per month), C (competitors) - the number of competitors in the issuance of PS. Of course, this formula is not ideal and has a limited scope (in particular, shows too high results for HF keywords), and besides it there are others. However, the essence is always the same.: KEI is directly proportional to the number of requests, and inversely proportional to the competition in the issuance.

I think after using KEI, your traffic will grow very well. Let's note one more feature of using keywords. If you use by 1-2 request splurge on writing time. Best to use 4 -20 keywords in one article with direct and indirect entries (indirect ones are those that were inclined in the process of use “word forms”, all requests do not have to be declined, only the main ones). The article should be received 5000-12000 characters. In the title, write to 20 keywords.

Also don't exceed the keyword nausea percentage on the page 5,5%-6%.

A few words about KEI.

I would use KEI while checking the citation index (TIC) и google PR, because these criteria (puzomerki) very strongly affect the place in the issue for a specific query.

Good luck moving forward keyword performance index formula I hope it will be useful to you. In the future, I'm thinking of doing my own service for evaluating sites, so don't get lost subscribe to feeds and bookmark the site. I’m thinking about a new one, I’ll blow it as soon as I release it, and there will be far from only KIE, but also other calculations and formulas.

If anyone has their own formulas for calculating competitors, please write with pleasure.
