What are CRO KPIs?
CRO KPIs are the most important numbers you track to measure whether changes to your website are improving business results.
For example, if you change a product page, simplify a form, test a new headline, or redesign your checkout, you need a way to tell whether that change actually helped. Did more people buy? Did more qualified leads come through? Did more visitors book a demo? CRO KPIs help you answer those questions.
A good CRO KPI should do three things:
Is your site converting as well as it could be?

- Second, it should be actionable, meaning a team can respond to it and improve it.
- Third, it should be specific enough to show whether a test, page change, or funnel improvement is working.
CRO metrics vs CRO KPIs
Not every metric is a KPI. You can track lots of numbers on a website, including bounce rate, scroll depth, clicks, pageviews, form starts, and add-to-carts. But a KPI is different. A KPI is a metric that helps you align your CRO goals to business goals.
If your goal is to increase revenue, your KPI might be purchase conversion rate, revenue per visitor, or average order value. If your goal is to generate better leads, your KPI might be qualified lead rate rather than just total form submissions. If your goal is to improve SaaS growth, you might track trial signup rate, activation rate, or trial-to-paid conversion.
| CRO metrics | CRO KPIs |
|---|---|
| Any numbers you track to understand what visitors are doing on your site | The few numbers you track to judge whether your site is improving a business goal |
| They help you spot behavior, such as where people click, where they drop off, or whether they start a form | They help you measure outcomes, such as whether more people buy, book a demo, or become qualified leads |
| Examples: scroll depth, CTA clicks, form starts, add-to-cart rate | Examples: purchase conversion rate, revenue per visitor, qualified lead rate, demo booking rate |
| Useful for diagnosing problems | Useful for judging whether a page change, test, or redesign actually worked |
11 CRO KPIs that actually matter
KPIs that measure revenue and conversions
These are the KPIs closest to the result most teams actually care about: more sales, more qualified signups, more demo bookings, or more revenue from the traffic they already have.
1. Conversion rate
Conversion rate is the percentage of visitors who complete the main action you want them to take, such as making a purchase, submitting a form, booking a demo, or starting a trial.
It’s often the first KPI teams look at because it’s one of the clearest ways to measure whether a page, funnel step, or test is performing better.
Here’s how to calculate the conversion rate:
Conversion rate = conversions ÷ total visitors × 100
KPIs that show where people move forward or drop off in the funnel
KPIs that measure lead quality

How to choose the right CRO KPI for a test or initiative
This should be a clear framework.
Start with the business goal
Examples:
- increase revenue
- increase qualified demos
- improve onboarding completion
- reduce abandonment
Pick one primary KPI
Avoid trying to "win" on everything at once. This aligns with Invesp's own advice on focusing goals.
Add 2-4 diagnostic KPIs
So you can explain movement.
Add 1-3 guardrail KPIs
So you do not create downstream damage.
Segment where it matters
Examples:
- mobile vs desktop
- paid vs organic
- new vs returning visitors
- product category or traffic source
Invesp's CRO strategy content already emphasizes segmentation and identifying bottlenecks before testing
