Revenue model
SEO ROI Calculator
Model what incremental organic sessions, conversion rate, close rate, customer contribution and monthly SEO investment could mean for return.
Use the result as one planning scenario. It does not prove the traffic is achievable, that SEO caused a sale or that the return will arrive in the same month.
Most SEO forecasts hide the leap between rankings and money. This model shows the five inputs separately so you can replace optimism with first-party evidence.
How to use it
- This is a planning model, not a forecast or guarantee.
- Use contribution after direct fulfilment costs, not headline revenue.
- Keep the period, attribution rule and source of every input consistent.
Use the calculator
Start from zero and enter one internally consistent monthly scenario. Use analytics and CRM rates, and use contribution after direct fulfilment costs rather than headline revenue.

Methodology
- Modelled leads = incremental monthly organic sessions × visitor-to-lead rate.
- Modelled customers = modelled leads × lead-to-customer close rate.
- Modelled contribution = modelled customers × average contribution per customer.
- Modelled net return = modelled contribution − monthly SEO investment.
- Modelled ROI = modelled net return ÷ monthly SEO investment.
Build the search investment case from real demand.
We can replace the scenario with a bounded market map, current search evidence, conversion data and an implementation plan your team can actually ship.
