According to a Stiplo analysis on hotel visibility in AI, just ten Barcelona properties represent only 1.5% of the city's hotel supply yet account for 22% of all mentions generated by ChatGPT, Google AI, Gemini, and Perplexity. While those top ten shine, the 20% of the 659 properties analyzed don't appear in any results whatsoever. It's a visibility gap that's starting to look structural.

What strikes me most is that each AI model has very defined favorites. There's no universal top ten, ChatGPT recommends one set of hotels, Perplexity another, and Google AI yet another based on their own algorithms. That means the Barcelona experience guests see varies wildly depending on which tool they use. And here's the point: Stiplo's data shows that your hotel visibility today depends on how your data trains in AI ecosystems you don't control.

For a distribution director or revenue manager, this is an opportunity, not a threat. If 20% of hotels don't appear, it's because they're not in the game. Those who are have a clear path: optimize metadata, polish reviews, be present in the sources that feed these models. Barcelona is still Barcelona, but now the battle for bookings runs through visibility on Perplexity and ChatGPT screens. If you're not there, you simply don't exist for half the travelers consulting AI before they decide.

Quick questions

Which Barcelona hotels appear in ChatGPT but not Google AI?

Stiplo's study shows each AI platform has different favorites based on its algorithm. There's no universal top ten in Barcelona, what you see in ChatGPT can be completely different on Perplexity or Gemini.

How many Barcelona hotels don't appear in any AI results?

According to the analysis, 20% of the 659 properties studied (roughly 130 hotels) don't appear in recommendations from ChatGPT, Google AI, Gemini, or Perplexity.

Why do 10 Barcelona hotels capture 22% of AI mentions?

Likely due to review volume, OTA presence, quality structured data, and positive historical feedback. They're feeding AI models better because they're reliable reference points the systems can trust.

How can I make my Barcelona hotel appear in AI recommendations?

Keep your data current on Google Business, major OTAs, and review platforms. Optimize descriptions with clear, structured information. AI models learn from reliable public sources your hotel must feed constantly.

Does this affect my direct bookings?

Yes, because more travelers now ask ChatGPT or Perplexity before searching OTAs. If you don't appear in those AI recommendations, you lose visibility in a discovery channel that's already decisive in Barcelona.
