Third-party providers can link from a business’s Business Profile on Google Search and Maps. These are called local business links. You can use these links to book an appointment, make a reservation, and place a food or shopping order with a provider.
When multiple providers supply links for the same business, Google lists them in random order. If the business specifies a preferred provider, that provider shows first.
For food orders, Google also lists providers in random order. However, if the business's website is available, or the business specifies a preferred provider, those show first.
When you use local business links on your mobile device, business preferred providers are labeled as such.
