It is important to verify your Facebook page for a number of reasons:-
1. It adds to the credibility of your page
2. It helps with higher ranking on Facebook.com/services and the Facebook Local application
3. It gives you more leverage to close a similar page down if you are the official page for the business.
4. Apparently, you get early access to new features (but I am not 100% sure on that!).
In this video, I will walk you through the steps of verifying your Facebook Page. Please note, this service is not available for those pages that are listed in Business Manager.
