Why calculating CRO ROI matters
It is easy to focus on Traffic (SEO, ads) and forget Conversion. This is the "Leaky Bucket" problem. If you pay for 10,000 visitors but only convert 1%, you are wasting money.
Increasing your conversion rate from 1% to 1.2% might seem small, but as the calculator shows, it is a 20% increase in revenue without spending a single extra dollar on ads. That is pure profit margin.
Frequently asked questions
What is a good conversion rate?
Averages vary a lot by industry, device and traffic source, so the most useful benchmark is your own: the "good" rate is simply better than last month. Continuous A/B testing helps you beat your own baseline.
How much traffic do I need to A/B test?
More traffic gives clearer answers sooner. Use our
sample size calculator to see how many visitors a test needs for the change you want to detect. On the Growth and Scale plans, Zyro's
bandit tests shift traffic toward the better version while the test runs.
How do I get an uplift?
Start by testing high-impact elements: headlines, offers and call-to-action buttons. Zyro's A/B tests (from the Starter plan) count the sales each version makes, so you keep what works and drop what doesn't.
