Enter the monthly search volume and the competition into the calculator to determine the Keyword Effectiveness Index (KEI).
Keyword Effectiveness Index Formula
The following formula is used to calculate the Keyword Effectiveness Index (KEI) for a given keyword.
KEI = (S² / C)
Variables:
- KEI is the Keyword Effectiveness Index
- S is the monthly search volume
- C is the competition
To calculate the Keyword Effectiveness Index, square the monthly search volume and divide by the competition. This will give you an indication of how effective a keyword is for SEO purposes.
What is a Keyword Effectiveness Index?
The Keyword Effectiveness Index (KEI) is a metric used in search engine optimization (SEO) to evaluate the effectiveness of a keyword. It is calculated by comparing the monthly search volume of a keyword to the level of competition for that keyword. A higher KEI indicates that a keyword has a high search volume but low competition, making it more effective and desirable for SEO purposes. Conversely, a lower KEI suggests that a keyword has high competition relative to its search volume, making it less effective for SEO.
How to Calculate Keyword Effectiveness Index?
The following steps outline how to calculate the Keyword Effectiveness Index (KEI).
- First, determine the monthly search volume for the keyword (S).
- Next, determine the competition for the keyword (C).
- Next, calculate the KEI using the formula KEI = (S² / C).
- Finally, calculate the Keyword Effectiveness Index.
- After inserting the values and calculating the result, check your answer with the calculator above.
