Google took the next step in its own vacation rental and apartments business, giving it special treatment with a four-pack display of rates, photos, reviews, and a map within Google search - and placement above other travel companies’ organic results.

With the alternative accommodations sector one of the fastest-growing segments in travel around the world, Google’s move is an assertion that it will be a major force.

If you search for vacation rentals in Chicago, Singapore, Mexico City, or London, for example, the keywords will trigger four results in a box from vendors including Vrbo, Agoda, Red Awning, Hotels.com, Expedia, Vacasa, Rentals United, and others. Prominently missing in action from the roster of Google vacation rentals participants is Airbnb.
