Tripadvisor faces a classic innovator's dilemma: the review platform that created its defensible moat is being displaced by transaction-based revenue from Viator, a unit that captures commissions on bookings rather than relying on advertising. This matters because it forces a strategic choice—double down on review network effects (increasingly commoditized by Google, social platforms, and AI), or pivot toward becoming a distribution layer for experiences, where Tripadvisor takes margin on every sale. The company's revenue trajectory now depends on whether it can scale Viator faster than its legacy review business decays, a shift that requires completely different operations and customer acquisition playbooks.
