Answer
For B2B websites, growth-driven design ships a lean site fast, then runs continuous sprints against real buyer behavior, which fits companies that depend on the site for lead generation and sales (SaaS, B2B services, inbound-led firms) [1]. Because B2B buying journeys are long and multi-touch, the value is in optimizing the whole path from first visit to sales-qualified lead, not a single page [2].
