Most businesses don't have a traffic problem — they have a conversion problem. CRO is the discipline of systematically improving the percentage of visitors who take the action you want.
This guide covers the fundamentals every team should master before running complex A/B tests.
The CRO loop
- Measure: baseline current conversion rates
- Investigate: analytics, heatmaps, session recordings, user interviews
- Hypothesise: define a clear change and predicted impact
- Test: A/B or before/after with statistical rigour
- Learn: ship winners, document losers
Highest-leverage areas
- Above-the-fold clarity (headline + value prop)
- Form length and friction
- Page speed and Core Web Vitals
- Social proof placement
- Pricing and CTA copy
Common CRO mistakes
Testing trivial colour or copy changes, running tests without enough traffic, declaring winners too early, and copying competitor tactics without understanding context.
Qualitative + quantitative
Combine analytics (what) with user interviews (why). Numbers tell you where to dig, conversations tell you what to change.
AI in CRO
AI accelerates research synthesis, hypothesis generation and copy variants — but the strategic decisions still belong to humans who understand the buyer.
