Google has expanded where the Structured data carousels (beta) search feature works and for what types of queries. When it first launched, about a year ago, it was available for flights queries in Germany, France, Czechia, and the UK. Now it is available for queries related to ground transportation, hotels, vacation rentals, local business, and things to do (for example, events, tours, and activities) in all European Economic Area (EEA) countries.

It's available for travel, local, and shopping queries. For shopping queries, it's being tested first in Germany, France, Czechia, and the UK.
