What is Conversion Rate Optimisation?CRO
Conversion Rate Optimisation (CRO) is the structured discipline of increasing the percentage of website visitors who take a defined action — request a quote, sign up, purchase — through evidence-based UX, copy, and funnel improvements.
CRO is not split-testing button colours. It is a research-first discipline that audits existing funnels, identifies friction, hypothesises specific changes, runs prioritised tests, and ships changes that compound. The leverage is enormous: a B2B site moving from 2% to 4% conversion doubles revenue from existing traffic. Most sites have so much friction that the first 90 days of disciplined CRO recovers 30–60% more conversions without any new traffic. Codnity Creative ships CRO in conjunction with web marketing tools, lead capture systems, and CRM integration so improvements are measured end-to-end.
What it includes
- Conversion funnel audit (every step from landing to closed)
- Heuristic and quantitative analysis (Hotjar, GA4, behavioural data)
- Hypothesis-driven test backlog
- A/B and multivariate testing framework
- Lead capture and qualification optimisation
- Form, copy, layout, and CTA refinement
How it works
Audit the funnel
Map every step. Identify drop-off points with quantitative data. Identify friction with heuristic and qualitative review.
Prioritise hypotheses
Score each hypothesis on impact × confidence × effort. Top 3 ship in the first sprint; the rest backlog.
Test and measure
A/B or multivariate where traffic supports it; before/after with statistical confidence where it does not. Document outcomes.
Compound the wins
Roll winning changes into the production site. Backlog new hypotheses. Repeat the loop monthly.
Frequently asked
How long until CRO shows results?
First wins (10–25% improvement on tested funnels) typically land in the first 30–60 days. Compounding gains take 6+ months as the test backlog rolls forward.
Do I need lots of traffic for CRO?
Statistical A/B testing requires meaningful traffic. Below ~5,000 monthly conversions, prioritise heuristic changes and qualitative research over controlled tests. Both are valid; match the method to the data.
Where does CRO fit alongside SEO and paid?
SEO and paid acquire traffic; CRO converts it. The three should run together — improving conversion makes every paid euro and every organic visitor more valuable.
