Calculate the cost of SEO and its Benefit
Frequently Asked Questions
How do you calculate the benefit of SEO?
The benefit of SEO is calculated by comparing the value of traffic and conversions SEO brings against the cost of your SEO efforts.
Step 1 – Measure traffic impact
Look at the additional organic visitors gained through SEO (using Google Analytics, Search Console, or other tools).
Step 2 – Apply conversion data
Identify how many of those visitors convert (e.g., leads, sales, sign-ups) by using your average conversion rate.
Step 3 – Assign a value per conversion
Estimate the revenue generated per lead or sale. Multiply this by the number of conversions from SEO traffic.
Step 4 – Compare with SEO cost
Subtract your SEO spend (agency fees, tools, content creation, etc.) from the revenue gained.
Step 5 – Calculate ROI
Use the formula:
SEO ROI (%) = [(Revenue from SEO – SEO Cost) ÷ SEO Cost] × 100
