How it works
- 1
Plug in today's numbers
Current organic traffic, conversion rate, and average order value. Pull these from Google Analytics or your CRM.
- 2
Set a realistic growth target
A ramped 50–100% YoY traffic lift is achievable in most non-saturated niches with focused content + technical work.

Add your monthly SEO spend
Use our SEO Cost Calculator if you don't have a number yet. We linearly ramp the traffic gain across your time horizon.
- 4
Read your payback + ROI
Payback month is when cumulative profit covers cumulative spend. ROI is end-of-horizon profit minus spend, divided by spend.
A small detail that compounds.
SEO is a delayed-payoff investment. Most teams give up at month 4 because they're comparing one month's spend to one month's traffic - and the math is brutal that way.
A proper ROI model spreads the spend, ramps the traffic, and shows you the real payback month. For most healthy businesses it's month 6–12, with a 3–5x ROI by the end of year one.
The fastest way to ROI is to lower the cost.
Two ways to push ROI up: grow traffic faster, or spend less to get there. Most teams obsess over the first lever and ignore the second.
Sight AI attacks the cost lever directly. By replacing the agency or in-house writer with our 13+ AI agents, you can drop monthly content production cost by 60–80% and use the saved budget on links, technical work, or simply pocket it.

Common questions.
How does the model project traffic?
We linearly ramp from your current to your target traffic over the time horizon. Real SEO traffic is closer to a hockey stick - slower for the first 3–6 months, then accelerating - but the linear approximation gives a conservative, easy-to-defend number.
What's a realistic conversion rate?
B2B SaaS: 0.5–2%. E-commerce: 1–3%. Services: 2–5% for inbound leads. If you don't know yours, plug in your last 90 days from Google Analytics.
Should I model paid search separately?
Yes. SEO ROI compounds; paid is a per-click cost. Use a separate model for PPC.
What if my growth target is too aggressive?
Then payback gets pushed out and ROI drops. Try 50% as a baseline; 200%+ is doable in low-competition niches but rare in saturated ones.
