AI referrals to U.S. travel sites nearly tripled in May. AI visitors spent more time on site and bounced less than visitors from traditional sources, according to Adobe.
By the numbers. Traffic from AI sources to U.S. travel sites grew 194% year over year in May 2026, Adobe said. It was up 2,215% since October 2024, when Adobe began tracking AI traffic.
- AI-assisted travel planning has expanded beyond early research. Travelers use large language models to compare destinations, evaluate hotel amenities, build itineraries, find promotions, and book trips.
AI visitors showed stronger engagement. AI-referred travel visitors still converted 28% less than non-AI traffic. That gap has actually narrowed nearly 70% since October 2024, Adobe said.
- Engagement metrics were stronger. AI-referred travelers were 21% more engaged than non-AI visitors, spent 70% longer per visit, and had bounce rates 41% lower.
- Adobe said those engagement patterns suggest more purposeful, high-intent behavior, though AI-referred travel visitors still converted at lower rates.
Travel pages and AI readability. Adobe also measured how readable travel websites are to large language models. Its AI Content Visibility Checker scores how much page content AI systems can read.
- Hotels and car rentals led the travel sector. Hotel homepages scored 63% readability, while car rental homepages scored 59%. Product pages scored higher: 73% for hotels and 71% for car rentals.
- Even so, more than one-third of content on some leading travel pages remained unreadable to AI systems, Adobe said.
Where travel sites scored best. Hotels led across several page types, including destination guides, activities, search results, customer service, and promotions pages.
- Car rentals led FAQ pages. Cruises led blog and news content. Airlines trailed the leading travel sectors across every page type Adobe measured.
- The pattern favored pages with rich, structured information. Property details, amenities, vehicle descriptions, and core offerings gave AI systems more content to parse.
Retail’s conversion advantage. AI referrals to U.S. retail sites also hit a record high in May, rising 138% year over year and 1,324% since October 2024.
- Retail AI traffic has progressed further on conversion. Adobe said AI-referred retail visitors converted 54% better than non-AI traffic, reversing last year’s pattern, when AI conversion rates were nearly half as high.
- Cosmetics and electronics led retail readability, aided by ingredient lists, tutorials, product specifications, how-to guides, and customer service content. Grocery and furniture lagged.
Why we care. Adobe’s data suggests AI referrals are becoming more commercially valuable, especially in retail, while its visibility scores indicate many sites still leave significant content inaccessible to AI systems. If key content is blocked, buried, or poorly structured, you may lose visibility before a traveler or shopper reaches your site.
About the data. Adobe’s findings were based on more than 8 million visits to U.S. travel sites, more than 1 trillion visits to U.S. retail sites, and more than 100 million SKUs. The company also surveyed more than 5,000 U.S. consumers in March about how they use AI for shopping and travel planning.
