Business accounts have their own features and opportunities on social media. One of the biggest is the coveted verification on the platform. Accounts that have been verified have a nice blue checkmark next to their name. It's visible when users view the profile. This builds more credibility with the audience. It doesn't hurt to try if you have a legitimate business and want to verify the account. You can also try again later if you were initially rejected. For many people, attempts last quite a long time, so they decide it's already easier to buy instagram verification.
