This document discusses optimizing marketing for niche business-to-business (b2b) clients compared to broad business-to-consumer (b2c) clients. It notes that b2b and b2c optimization differ because b2b deals have longer sales cycles, higher transaction values that vary greatly, and a smaller percentage of visitors are convertible leads. The document recommends optimizing for pipeline value (PVO) rather than conversion rate (CRO) for b2b. It provides examples of successful b2b landing page optimizations and emphasizes the importance of input from sales on lead quality for measurement.
