CRO (Conversion Rate Optimization)
What is CRO?
CRO (Conversion Rate Optimization) is a data-driven methodology that aims to improve the percentage of visitors who complete a desired action on your website. This action can be a purchase, subscription, document download, or any other action aligned with your business objectives.
The conversion rate is calculated simply: (Number of conversions ÷ Number of visitors) × 100. For example, if 100 people visit your site and 3 buy your product, your conversion rate is 3%.
Why is CRO crucial for your business?
ROI Maximization: Rather than increasing your acquisition budget, CRO optimizes the value of your existing traffic. Doubling your conversion rate equals doubling your revenue without increasing acquisition costs.
Enhanced user experience: CRO identifies and removes friction points that prevent your visitors from achieving their goals on your site.
Competitive advantage: A conversion-optimized site performs better than the competition, even with equivalent traffic.
CRO Methodology: A scientific approach
1. Analysis and Audit
- Google Analytics data analysis, heatmaps, session recordings
- Identification of high-potential improvement pages
- User journey mapping and friction point detection
2. Hypothesis formulation
- Hypotheses based on behavioral data
- Prioritization according to potential impact and ease of implementation
- ICE framework (Impact, Confidence, Ease) to prioritize tests
3. A/B and multivariate testing
- Creation of page or element variants
- Statistically significant tests on representative samples
- Measurement of impact on conversions and secondary metrics
4. Results analysis
- Data interpretation with statistical rigor
- Understanding user behaviors revealed by tests
- Documentation of learnings for future optimizations

Expected results from a CRO strategy
A well-executed CRO strategy can generate improvements of 10% to 300% in conversion rate depending on sectors and initial site state. Beyond numbers, CRO globally improves user experience and strengthens brand trust.
CRO is not a one-time optimization but a continuous improvement process that adapts to your audience and market evolution. It's the essential scientific approach to transform your Webflow site into a conversion machine.
