From my initial research, the major contenders include Google, Bing, Yellow Pages and Yelp. If you conduct a business search on a mobile device, you see that businesses are usually prioritized by their proximity to you. Most online listings look and operate like this, but not every business takes advantage of them, which may result in a significant loss of potential customers.
Online local listings can help businesses engage their customers through reviews and comments. Though customer feedback may seem intimidating, doing so can help develop a brand image and boost sales.
Negative comments and reviews can help fix problems that wouldn’t have been known about otherwise. A prudent business should take steps to make sure they get more positive reviews down the road.
