What tools do conversion optimization consultants use?

CRO consultants use various tools: analytics platforms (Google Analytics, GA4) for understanding user behavior, heatmap tools (Hotjar, Crazy Egg) for visualizing interactions, A/B testing platforms (Optimizely, VWO, Google Optimize) for running experiments, session recording tools for watching user sessions, survey tools for gathering feedback, and funnel analysis tools. They also use statistical calculators to determine sample sizes and significance. Many consultants have preferred tool stacks, but the best ones adapt tools to client needs and budgets. Some tools offer free tiers suitable for smaller sites. The key is using tools that provide actionable insights, not just data.
