Conversion Rate Optimization is the craft of turning more of your existing traffic into customers. It's usually the cheapest path to revenue growth: you already have traffic; you already have a product; fix the leaks in your funnel and the whole thing scales. This 70-page section covers research (understanding why users DON'T convert), frameworks (prioritizing what to test), landing pages, conversion copy, testing methodology, analytics, and the tools. CRO is detective work with math. When it's working, it compounds quietly; every future marketing dollar goes further.
