What Is Conversion Rate Optimization (CRO)?
CRO is the art of getting more from the traffic you already have. Here’s what it is, why it matters, and how to start testing.
Conversion rate optimization (CRO) is the practice of increasing the percentage of visitors who take the action you want — buy, sign up, enquire — without needing more traffic. It’s one of the highest-leverage things you can do.
Why CRO matters
Traffic is expensive; improving conversion makes every visitor you already have worth more. A jump from 2% to 3% is a 50% increase in results from the same traffic.
Where to focus first
- Clarity — is it obvious what you offer and what to do next?
- Friction — remove steps, fields and distractions between intent and action.
- Trust — reviews, guarantees and clear policies reduce hesitation.
- Speed — slow pages quietly kill conversions (see our speed guide).
Test, don’t guess
The heart of CRO is testing: change one thing, measure the effect on conversion, keep what wins. Base decisions on data and real user behavior, not opinions. Start with your highest-traffic, highest-intent pages for the biggest impact.
