Guides
How much is a single website visitor actually worth? Divide revenue by visitors and you have your baseline — add conversions and ad spend to unlock conversion rate, average order value, and traffic ROI on top.
How to use it
- Enter your website revenue and total visitors for a period.
- Pick the time period (day, week, month, or year) — used to annualize revenue and visitors.
- Optionally add conversions (orders, signups, leads) to see conversion rate and average order value.
- Optionally add ad spend for the same period to see cost per visitor, traffic ROI, and profit per visitor.
The formulas
Visitor Value = Website Revenue ÷ Visitors
Annualized Revenue = Revenue × periods per year for the selected time period
Annualized Visitors = Visitors × periods per year
Conversion Rate = Conversions ÷ Visitors × 100
Average Order Value = Revenue ÷ Conversions
Cost per Visitor = Ad Spend ÷ Visitors
Traffic ROI = (Revenue − Ad Spend) ÷ Ad Spend × 100
Profit per Visitor = Visitor Value − Cost per VisitorWhat is Visitor Value actually used for?
It's the number that turns "how much traffic should I buy?" into a real budgeting question. If a visitor is worth $0.50 on average, paying more than $0.50 per visitor in ads is a loss before you even account for other costs — paying less leaves room for profit.
Why annualize revenue and visitors?
Comparing a daily, weekly, or monthly snapshot to an annual marketing budget or investor projection needs a like-for-like number. Annualizing multiplies your period's revenue and visitors by the number of that period in a year (365 days, 52 weeks, 12 months) so you can compare directly.
How is Traffic ROI different from ROAS?
Traffic ROI here is net return — (Revenue − Ad Spend) ÷ Ad Spend, expressed as a percentage, so 0% means you broke even and negative means you lost money on the spend. ROAS (return on ad spend) is usually reported as gross revenue ÷ spend instead, which reads as "300%" even at breakeven-plus-costs — Traffic ROI is the more conservative, profit-focused version of the same idea.
