When you make the change, you’ll have access to additional fields appropriate to the business page, so you can fill in your business information. Likewise, the new category will appear in search results and follow the business category’s layout.
Log in to your Facebook page. If you’re on your personal profile, click the page name from the left panel’s Pages section.
Click the “Edit Page” drop-down menu and select “Update Info.”
