Root Causes
Key Lessons Learned
1. Platform dependency is existential risk
When your traffic source becomes your competitor, decline is inevitable. TripAdvisor got 50%+ of traffic from Google, which then built competing features.
2. Review moats erode when aggregated
User-generated reviews seemed like an unassailable moat until Google aggregated reviews from multiple sources directly in search results.
3. Pivot timing determines survival
TripAdvisor's pivot to experiences and direct booking came too late, after Airbnb Experiences and GetYourGuide had captured the market.
