Directory citations are an important part of any SEO strategy. They give your business broad exposure across search with consistent business information such as name, address and phone number (NAP). Of all business directories or listings that your business should be in, the Google business listing, now called Google My Business is the one you want to make sure your business has a claimed and verified listing.
A verified Google My Business listing will get you listed in search and on maps. With the right optimization and reviews your business has a chance to be displayed in organic search in the Google 3 pak usually near the top of the page right under the ads and just before organic results.
You will need a Google account like for Gmail. Be sure to add images and description to your listing. Once everything is setup and verified you will be able to update and manage your listing from the Google My Business dashboard.
