All kinds of businesses create a Facebook page (vs personal profile) for their businesses, because it’s a great way to reach people both locally and worldwide. People can find your page, and they can interact with your business through it by checking in, liking it and what is posted on it, sharing it, and more. This is good marketing and is very cost-effective as well.
In order for people to know that this is the official page for your business, you’ll need to verify it. This help page explains how you can verify your page on Facebook, which lets people know it is a genuine business page.
