There are certain things which can't be added to your profile, or other restrictions which are in place when you are developing the profile page. This can range in things such as the number of characters you can use for your headline, to the size of an image you can use on the main page of your profile.
Understanding the restrictions, knowing what limits are in place and understanding what you can and can't do on the site, are a few things to keep in mind as well as you are developing your page. It will not only eliminate your Instagram account from being flagged, and eventually deleted, it will also make setting up the page much easier for you as well. So, understanding how to optimize your profile, all while understanding the limitations that are in place, is something that you must understand as a business owner who is setting up your account for the first time.
