Google’s advice for improving local search ranking.
Local results appear for people who search for businesses and places near their location. They’re shown in a number of places across Maps and Search. For example, you’ll probably see local results if you search for “Italian restaurant” from your mobile device. Google will try to show you the kind of nearby restaurant that you’d like to visit. In the image below, Google uses local results to suggest some options.
Prominence refers to how well-known a business is. Some places are more prominent in the offline world, and search results try to reflect this in local ranking. For example, famous museums, landmark hotels, or well-known store brands that are familiar to many people are also likely to be prominent in local search results.
Prominence is also based on information that Google has about a business from across the web (like links, articles, and directories). Google review count and score are factored into local search ranking: more reviews and positive ratings will probably improve a business’s local ranking. Your position in web results is also a factor, so SEO best practices also apply to local search optimization.
