This is a scenario, not a forecast
Every output comes from your assumptions. The model ramps the expected click lift linearly, applies your conversion value and gross margin, then subtracts the monthly SEO cost. It does not infer rankings, algorithm changes, attribution or demand growth.
Monthly projection
Bars compare modeled incremental gross profit with monthly SEO cost.
