Enter the total increase in traffic (visitors), the value of each visitor ($/visitor), and the cost spent on SEO ($) into the Return on SEO Calculator. The calculator will evaluate and display the Return on SEO. 

Return on SEO Formula

The following formula is used to calculate the Return on SEO. 

ROSEO = (T * V  – C) / C * 100

  • Where ROSEO is the Return on SEO (%)
  • T is the total increase in traffic (visitors) 
  • V is the value of each visitor ($/visitor) 
  • C is the cost spent on SEO ($) 

How to Calculate Return on SEO?

The following example problems outline how to calculate Return on SEO.

Example Problem #1

  1. First, determine the total increase in traffic (visitors).
    • The total increase in traffic (visitors) is calculated to be : 600.
  2. Next, determine the value of each visitor ($/visitor). 
    • The value of each visitor ($/visitor) is measured to be: 3.
  3. Next, determine the cost spent on SEO ($). 
    • The cost spent on SEO ($) is found to be: 1000.
  4. Finally, calculate the Return on SEO using the formula above: 

ROSEO = (T * V  – C) / C * 100

The values given above are inserted into the equation below and the solution is calculated:

ROSEO = ( 600* 3  – 1000) / 1000 * 100 = 80 (%)


Example Problem #2

The variables needed for this problem are provided below:

total increase in traffic (visitors) = 700

value of each visitor ($/visitor) = 4

cost spent on SEO ($) = 1500

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.
