Google is testing AI Overviews inside the hotel side panel of its search results, expanding the AI-generated answer format into another commercially significant vertical.

Search Engine Roundtable editor Barry Schwartz, who spotted and documented the test, shared a screenshot showing an AI Overview appearing alongside hotel results in the side panel — the knowledge-panel-style area Google displays for lodging queries. The experiment mirrors the AI Overview treatment Google has already rolled out for standard web results, now applied to a hotel-specific surface.

This is a test, not a confirmed rollout. Google regularly runs live experiments on small percentages of search traffic, and many interface tests never reach general availability. The company has not issued a statement confirming when or whether AI Overviews in the hotel side panel will launch broadly.

For hotel brands, online travel agencies and metasearch players, the test signals where Google's travel SERPs may be heading. The hotel side panel already aggregates rates, photos and booking links from partners; adding an AI-generated summary layer could change how much direct traffic escapes to publisher and OTA sites versus staying within Google's interface.

Travel is one of the verticals where AI Overviews have drawn the closest scrutiny from search professionals, since AI-generated answers can satisfy informational queries — "best hotels near the Eiffel Tower," for example — without the user clicking through. A hotel-side-panel placement pushes that dynamic directly into transactional territory, where clicks convert to bookings.

What to watch next: whether Google expands the test beyond a limited user pool, whether the AI Overview content in the panel draws on the same source citation format used in standard AI Overviews, and how any broad launch affects click-through rates for hotels, OTAs and travel content sites that currently rely on side-panel visibility.
