SEO ROI Calculator
Turn your monthly SEO investment into a clear commercial return. Enter your cost, organic traffic, orders or leads, and total revenue to see exactly what your organic channel is delivering.
How to Use This Calculator
Four inputs, one clear ROI number. Built for marketing leads and business owners who need to justify SEO investment in commercial terms.
Enter your monthly SEO cost
Include everything: agency retainer or freelancer fees, tools (Ahrefs, Semrush), content production, and link building spend. Use a monthly total.
Add your organic visit volume
Pull monthly organic sessions from Google Analytics 4 or Search Console. Use the same period as your cost figure for an accurate like-for-like.
Enter your monthly orders or leads
The total number of purchases, sign-ups, or qualified leads generated from organic traffic in the same period. Find this in GA4 by filtering conversions to the organic channel.
Enter total revenue from SEO
The total revenue attributed to organic search — pulled directly from your analytics platform or CRM. No need to calculate an average; just enter the total for the period.
Read your ROI and efficiency metrics
The calculator derives conversion rate, revenue per order, cost per visit, and cost per conversion automatically — plus a full ROI % for board-level reporting.
Use the insight to take action
High ROI → scale. Moderate → optimise conversion rate or deal value. Low → review funnel. Negative → check attribution and consider whether SEO is in a growth phase.
