The document discusses various techniques for conversion optimization, including setting goals and measuring key metrics, conducting technical, heuristic and analytics-based research, using Google Analytics to identify opportunities, implementing A/B testing, and learning from test results even when hypotheses are not validated. Some specific techniques covered are mouse tracking and heatmaps to understand user behavior, on-page surveys, remote user testing, prioritizing high-impact opportunities, and ensuring tests are properly designed and sample sizes are sufficient. The overall goal is to follow a continuous process of gathering data, generating hypotheses, testing ideas, and using results to further optimize conversions and business performance.
