The Google Knowledge Graph Carousel was seen showing up more frequent and wider variety of search results in the recent days. The reason behind is an announcement of the official launch of Carousel for local search results in a Google+ post.
Google has revealed that whenever a user will search for restaurants, bars, or other local places from the desktop, he will get horizontal Carousel display of images at the top of the results.
Users can scroll through the images or zoom in on the map to see the results for a particular area. If they happen to click on an image in the Carousel, more location details including the review-based score, photos, and address will appear.
The Carousel results will be rolled out in English in the U.S. and more features & languages will be added with time.Google Launches the Knowledge Graph Carousel for Local Search!,
