It is important to claim and optimize your Google My Business (GMB) listing is the most important part of local SEO, although Bing Places and Apple Maps listings are important too.
According to Moz, GMB is one of the top local ranking factors for both “snack pack” and organic results.
What is Google Snack Pack
Google Snack Pack is the boxed area that appears on the first results page when a local online search is made through Google’s search engine. The Snack Pack box displays the top 3 local business listings most relevant to the search enquiry.
A big part of local SEO is making your Listings profile as up-to-date and accurate as possible so that it has a higher chance of appearing in the local pack, and trustworthy, attractive and appealing enough to warrant a clickthrough. Although it’s incredibly powerful, Google My Business is just one example of what’s known as a ‘citation’.
Local Citations (NAP)
Local Citations are online mentions of your business, which display your business name, address, and phone number. They are known together as NAP (Name, Address, Phone).
