Other monthly SEO costs (optional)

Recurring staff, content, development or tool costs.

Profitability and forecast period

Add margin for profit-based ROI, then choose how far ahead to project.

Gross profit margin (optional)

What this model assumes

Assumptions and methodology

Growth builds gradually

The model uses a smooth S-curve, starting slowly and reaching your chosen growth assumption in the final month.

Only incremental performance counts

Results show the additional orders, revenue and gross profit above your current monthly organic baseline.

ROI is profit-based

ROI compares incremental gross profit, less SEO investment, with that investment. It is not a revenue-to-cost ratio.

A planning estimate, not a promise

Results depend on the figures you enter. Competition, search changes, implementation, seasonality, stock, pricing and market conditions can affect actual performance. Treat this forecast as a planning tool, not a guarantee.
