According to the Moz 2018 local search ranking factors study, NAP consistency is really important for local SEO. Building local citations with consistent NAP (Name, Address, Phone Number) data on your Google My Business (GMB) profile and listed online addresses can affect your search rankings.
First, Google decides where to rank your business by dragging out NAP data from your GMB profile. Thereafter, it compares your NAP data from your GMB account with the NAP listed on different online directories, your social media, and website.
Having a consistent NAP also makes it easier for potential customers to find accurate information about your business. Inconsistent NAP data can make users frustrated and lose potential leads. So, optimizing for NAP presence can help you validate your business across a wide range of sources and rank well in local search results.
