Trust is important online. Make sure your Facebook business and Instagram accounts are verified. You'll receive a trust icon that tells people you are legitimate.
Facebook verification simply confirms you are the business you claim to be, which prevents identity theft.
The process is very simple.
For Instagram verification, the process is a little bit different. You need to apply for verification and then they will go back through your business profile to determine whether or not you are who you say you are.
Be aware that this process can take a while. If it makes you feel any better, it took Andrew "Cosi" Costello ages to get his verification, despite his massive following on Instagram.
