One feature (limitation) of Instagram is that you can't include clickable links in a post message. So if you're running a business or are a personality of interest, you might share something that your followers might actually care to look into in more depth off-platform.

But then you have to tell them to check your profile for your one allowed link, go to your site, search for the product/blog/video - or you pay for an ad with links enabled.
