Which sources do AI tools rely on when recommending hotels?
Short answer
AI tools that recommend hotels generally combine what their models learned in training with information retrieved from the web when a question is asked. Retrieved sources commonly include hotel websites, Google Business Profiles and maps data, online travel agencies and metasearch sites, review platforms, travel publications, tourism boards, and local guides. Exactly which sources each product uses — and how it weighs them — isn't publicly documented in detail. Many tools show cited links, which tell you which pages they used for a given answer. Make your own website the most complete source, then make sure the others agree with it.

The main source types
- Your website — room, location, policy, and amenity pages. The one source you fully control.
- Business listings and maps — your Google Business Profile, address, hours, photos, and reviews.
- OTAs and metasearch — descriptions, amenities, and guest reviews on booking platforms.
- Review platforms — what guests say about specific experiences.
- Editorial sources — travel publications, newspapers, local guides, tourism boards.
- Community content — forums and discussion sites where travellers compare options.
What's documented — and what isn't
- Google states its AI features rely on its normal Search index: pages must be indexed and eligible to show with a snippet.
- OpenAI documents that OAI-SearchBot surfaces websites in ChatGPT search, and Perplexity documents PerplexityBot for its search results.
- How each product chooses and weighs sources for a specific answer is not public. Be cautious of anyone claiming to know the exact formula.
Use citations as a map
When a tool shows sources for an answer about your area or hotel:
- Record which pages are cited.
- Check whether those pages describe you accurately.
- If a cited page is wrong, request a correction or update your listing there.
- If your own site is never cited, check whether it clearly answers the question being asked.
How to strengthen each source
- Website: plain-text facts, one clear page per topic, indexable. See what answer engines need.
- Business Profile: complete and accurate. See optimizing your Business Profile.
- Listings: same facts as your website.
- Reviews: genuine, answered thoughtfully.
- Editorial: earn coverage with newsworthy stories and local expertise. See third-party guides and AI.
Common mistakes
- Optimizing only your website while listings stay outdated.
- Assuming one tool's citations apply to all tools.
- Paying for low-quality directory listings to "feed" AI tools.
Checklist
- Website is the most complete source about the hotel
- Business Profile and major listings match it
- Cited sources recorded during regular checks
- Inaccurate cited pages corrected
- Plan for earning genuine editorial coverage
