Google's Business Profile Help says local results are mainly based on relevance, distance and popularity, and its section heading calls the third factor prominence. It defines distance as how far each business is from the customer who is searching, and prominence as how well-known a business is. Prominence also draws on how many websites link to a business and how many reviews it has, and Google says more reviews and positive ratings can help. Google's Business Profile Help also says there is no way to request or pay for a better local ranking on Google.
