Conversion Rate Optimization Fundamentals and Experimentation Questions

Covers core conversion rate optimization principles and experimental methodology. Candidates should understand the conversion funnel, common CRO levers (value proposition clarity, form-field reduction, trust signals, urgency, page speed), hypothesis generation, test design (A/B and multivariate testing), sample size and statistical significance, test prioritization frameworks (impact versus effort), experiment implementation and QA, metrics to measure success, and iterative learning from experiments. This also includes tools and platforms for experimentation and the practical tradeoffs between speed, risk, and interpretability when running tests across landing pages, email, and product interfaces.
