So the pitch here is, I think—make a full website to accompany your instagram posts, just as easily as you posted the photo itself.

You cannot post URLs in your post, but you can in your bio.
IG makes its money on advertising inside of the platform. As a result, they want to limit the ability of creators' to create their own ads by linking out to non-IG properties.
