How it works
- Extra visits grow in a straight line from none to your target over the months you set, then stay there. Set the ramp to 0 to start at full effect.
- Conversions are visits times the conversion rate, revenue is conversions times their value, and return on investment is revenue minus cost, divided by cost.
- It pays for itself in the first month that the running total of revenue reaches the running total of cost.
The background
A model, not a forecast
Every number here comes from your own assumptions. Be conservative with visits and conversion rate: base them on your analytics and past results where you can, and check how the answer changes if they are half what you hope.
Use profit, not price
If a sale is worth €100 but costs you €60 to fulfil, its value for this calculation is €40. Counting the full price makes any investment look better than it is.
Why SEO takes time
Search traffic usually builds over months as pages are found, trusted and ranked, so the first months cost more than they return. Results also keep coming after you stop spending, which this model does not count.
