What can I do to help my business show up in Local in the Facebook app?
To help your business show up in Local in the Facebook app, make sure you've added all of your basic Page information to your Page. Page information includes the name, category, address, phone number, store hours, username and short description about your business.
The strength of your Page's connections matters as well. Results are personalized and different for everyone. If someone wants to find restaurants in a particular city, places that their friends have recommended or checked into can be displayed higher. Results that are similar to the people, places and things that a person is already connected to can also be displayed higher.
