Both Google Maps listings and local 3-pack rankings are determined by unique factors compared to organic search. One important factor is a claimed, verified, and accurate Google Business Profile page. Another factor is citations: the quality and consistency of the company’s citations across the web on sites like Yelp, Foursquare, BBB, or Facebook, the higher potential that location has to rank. Other factors include customer reviews, Google Business Profile setup, and proximity of search users to the location itself.
