Conversion rate optimization CRO testing strategies

Master conversion rate optimization with systematic testing methodologies and user experience improvements. CRO fundamentals: 1. Conversion funnel analysis: traffic sources, landing pages, checkout process, abandonment points. 2. User behavior analysis: heatmaps, session recordings, user flow analysis, friction identification. 3. Performance benchmarks: industry averages, internal baselines, goal setting (10-20% improvement targets). Testing methodology: 1. Hypothesis formation: data-driven assumptions, expected outcomes, statistical significance planning. 2. Test prioritization: PIE framework (Potential, Importance, Ease), ICE scoring, resource allocation. 3. Sample size calculation: statistical power, confidence level (95%), minimum detectable effect. Landing page optimization: 1. Above-the-fold elements: headline clarity, value proposition, call-to-action prominence. 2. Trust signals: testimonials, security badges, social proof, guarantees, company logos. 3. Form optimization: field reduction, progress indicators, error handling, mobile-friendly design. A/B testing best practices: 1. Single variable testing: isolated changes, clear attribution, controlled experiments. 2. Test duration: statistical significance achievement, seasonal considerations, traffic volume requirements. 3. Results interpretation: confidence intervals, practical significance, winner validation. Advanced optimization: 1. Multivariate testing: multiple elements, interaction effects, complex page optimization. 2. Personalization: dynamic content, behavioral triggers, segment-specific experiences. 3. Mobile optimization: thumb-friendly design, page speed, simplified navigation. Tools and implementation: Google Optimize, Optimizely, VWO for testing platforms, Google Analytics for conversion tracking, heatmap tools (Hotjar, Crazy Egg) for user behavior analysis.
