SEO ROI Calculator
SEO return with the ramp modelled. Gains arrive gradually, so a calculation using the end-state traffic across the whole period overstates the return by roughly half.
Also called: seo return on investment, organic traffic value.
3.74x over 12 months: $5,391,360.00 of incremental revenue against $1,440,000.00 of spend. Break-even arrives around month 3, and the traffic would cost $2,764,800.00 to buy.
How this is calculated
Traffic gains are assumed to build linearly across the period rather than appearing on day one, which is the single biggest source of overstatement in SEO business cases. Revenue accrues on the incremental traffic only. The paid equivalent, what the same traffic would cost to buy, is the fairest comparison, and unlike ad spend the asset keeps working after the invoice stops.
traffic gains ramp over the period rather than arriving at once, so the sum matters more than the end state- v

Method and limits
What it assumes
- A linear ramp in traffic, which is optimistic in month one and pessimistic later.
What it deliberately does not model
- Rankings are not guaranteed and an algorithm change can remove the gain.
- It does not model the decay if investment stops, which is slow but real.

Frequently asked questions
- How long before SEO pays back?
- Typically six to twelve months, because the traffic ramps rather than arriving at once. Any model showing month-one payback has assumed the end state applies throughout.
