How to use SEO ROI

  1. Enter the current traffic and expected percentage uplift.
  2. Add conversion rate, value and margin where you have defensible estimates.
  3. Compare the estimated contribution with the cost for the same time period.

02 / interpret the output

What the result means

Additional visits are current traffic multiplied by expected uplift. Additional conversions are visits multiplied by conversion rate. Revenue and contribution then use the supplied value and margin.

Important considerations

  • An SEO forecast is not a guarantee of traffic, rankings or revenue.
  • The model does not include seasonality, branded/non-branded mix, costs beyond SEO or attribution uncertainty.
  • Use ranges and scenarios where the inputs are uncertain.

Worked example

Model 10,000 visits, a 25% uplift, 2.5% conversion and £250 value, then compare the result with the actual cost and margin assumptions.
