It's normal for your visibility to differ a lot between ChatGPT, Gemini, Perplexity and Google AI Overviews. For the same prompt, you might be recommended on one platform and not mentioned at all on another.
Why this happens
Each AI platform searches the web in its own way and prefers different sources. Some examples from our data:
ChatGPT often reads hotel websites.
Google AI Overviews often relies on Google's own sources, such as Google Business Profiles and YouTube.
Gemini and Perplexity often draw on booking sites, review sites, travel guides and blogs.
If the sources a platform prefers contain the right information about your hotel, it's more likely to recommend you. These preferences can change whenever a platform updates its model or its search.
