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.

STEP 01

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.

STEP 02

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.

STEP 03

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.

STEP 04

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.

STEP 05

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.

STEP 06

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.
