Google Business Profile is a free and easy way to manage your Google listings. It makes it easy for potential customers to find you on Google and see what else you have going on in your business. You get a Google My Business page for your business, which shows up when someone searches for your business name or keyword, like “coffee shop” or “coffee”.
If you don’t add your phone number to the listing, users will see an unhelpful link that says something like “no information available.” This article explains how to properly add your phone number on Google My Business so people can easily find you.
