When users search for local results, Google shows nearby businesses with addresses, Zagat ratings and Google reviews from its Google Plus Local service. (Google owns Zagat.) Regulators have interviewed competitors like Yelp, whose executives say that Google has filled prime real estate on the search results page with its own listings.

In that same search, by hovering a mouse over a listing (in this case, the top result), the right side of the page shows a Google map, reviews and ratings of the business from Google Plus Local and photos of the store, some shot by Google. Below that are links to reviews from other review sites that compete with Google Plus Local. Under the "People also search for" header, users are shown similar listings and photos from Google. Places.
