How to calculate SEO ROI
Start with added revenue, not added visits. Turn it into profit, then weigh it against what you spent.
- Traffic to sales to revenue
- Why margin changes the answer

How to forecast organic traffic
Good forecasts use ranges, not one hopeful line. Base them on search demand and where you rank today.
- Low, likely and high cases
- Growth curves that ramp up slowly
-
How to build an SEO business case
A budget request lands when it shows cost, expected return and payback month. Keep it to one page.
- What a CFO asks first
- Stating your assumptions openly
-
SEO vs paid ads
Paid ads stop when the spend stops. SEO costs more at first and less per sale later. Compare both over two years.
- Cost per sale over time
- When to run both at once
-
How long SEO takes to pay back
Payback depends on your margin, sales cycle and starting point. Shops often see it sooner than B2B teams.
- Finding your break-even month
- Long sales cycles in SaaS
-
SEO KPIs that matter
Rankings and visits are signals. Revenue, leads and cost per sale are the results. Report the results first.
- Tying GA4 data to revenue
- Dropping vanity metrics
The ROI formula, worked through once
Most SEO ROI maths goes wrong in one place. It counts revenue as if it were profit. Use gross profit instead, and the answer gets honest fast.
ROI = (gross profit − SEO cost) ÷ SEO cost
The figures here are a sample, not a client result. Swap in your own numbers with the calculator.
Six metrics a CFO and a marketer share
These terms come up in every guide. Here they are in plain words, so both sides of the budget talk mean the same thing.
- ROI Return on investment
- Profit gained minus cost, divided by cost. It tells you what each dollar earned back.
- ROAS Return on ad spend
- Revenue divided by ad spend. It ignores margin, so a high ROAS can still lose money.
- AOV Average order value
- Total revenue divided by the number of orders. It turns sales into a revenue figure.
- CAC Customer acquisition cost
- What you spend to win one new customer. Compare it by channel.
- LTV Lifetime value
- The revenue one customer brings over the whole relationship. Key for SaaS payback.
- CR Conversion rate
- The share of visits that become a sale or lead. Small changes here move ROI a lot.
