The document summarizes a presentation given by Michal Parizek at the #convcon 2013 conference in Chicago on conversion rate optimization maturity models. It discusses the key pillars of a mature CRO strategy, including investing in people over tools, following an optimization cycle of analysis, testing, and improvements, prioritizing initiatives correctly, planning both long- and short-term, testing iteratively, learning from every test, getting tools that match needs/skills, and having executive sponsorship. The goal is to help companies execute CRO more effectively by understanding different maturity stages.
