The Five-Way Split

For the first time in any AIVO study, all 5 engines picked a different #1 brand. There is no consensus leader in travel AI — Airbnb leads by total mentions (786) but each engine has its own preferred recommendation.

Airbnb: The Most Competitive Category

Travel is the most fragmented AI recommendation landscape we've ever studied. Unlike footwear (Crocs sweeps all 5) or beauty (e.l.f. takes 4 of 5), no travel brand can claim AI dominance. Airbnb's slim lead over Hilton (786 vs 773) is statistically marginal — this is a true five-horse race.

Full Brand Visibility Rankings

Each brand's AI Visibility Score (0–100) measures how often it appears across 1,500 queries. The gap between digital-native brands and legacy names tells a clear story about what AI values.

Visibility Score = % of queries where the brand was mentioned by AI engines. Higher is better.
