It means that if you have a GMB listing, your chances of appearing in the Local Pack are much higher than if you are focusing on ranking factors such as links, reviews, citations, etc. For this reason, it’s very important to have control over the information included under your GMB profile. Having a GMB listing is important is that, according to Google, verified businesses are twice as likely to be considered reputable by users.
