One of the common things that I see when I speak with business owners about Conversion Rate Optimization is a misconception of the field. While some may think of CRO as a means to a single, optimized endpoint is really in iterative, procedural process.
It is a field based in research, testing, and learning; what it essentially boils down to is experience. Who has more experience than those who dedicate their life and careers to CRO? As in any industry, there are those who continually learn and redefine their strategies, generating a foundation upon which to refine and build on their process.
