How to Calculate
ROI for SEO
The ROI formula for SEO measures the profitability of your SEO efforts by comparing the revenue generated from SEO to the cost incurred. Here's the standard formula:
The total number of visitors coming to your website from unpaid (organic) search results.
Organic Search Traffic
The percentage of organic visitors who complete a desired action (making a purchase, filling out a form, booking a call).
Conversion Rate (%)
The average total revenue generated by a customer over the entire time they do business with you.
Customer Lifetime Value (LTV)
The total amount invested in SEO over the time period you're measuring.
SEO Cost ($)
Based on these numbers, here's what you can expect in terms of return on investment*

SEO Revenue = The revenue generated from organic traffic (typically estimated using traffic × conversion rate × average order value or customer lifetime value).
SEO Cost = Total cost of SEO efforts (can include agency fees, tools, internal team
salaries, etc.).
Interpreting the Result
A positive ROI means SEO is profitable.
A negative ROI means you’re spending more than you're gaining, indicating room for
optimization.
Why SEO ROI Matters
Understanding your SEO Return on Investment (ROI) isn't just about crunching numbers - it's about clarity, accountability, and strategic growth. Here's why tracking SEO ROI is essential:
Demonstrating a positive ROI helps validate your SEO spending to stakeholders and ensures your digital marketing budget is allocated efficiently.
When you know what’s working, you can double down on high-performing strategies—whether it's content, backlinks, or technical SEO—and eliminate wasteful efforts.
ROI data allows you to project future returns, helping you prioritize SEO compared to paid advertising, social, or email in your broader marketing mix.
SEO isn't just about rankings—it's about business results. ROI connects SEO activities directly to revenue and profit, ensuring alignment with KPIs that matter.
