Not seeing many answers to the question. Snapchat is great for brand engagement and is basically guaranteed content, versus other platforms where you fight to get seen. It is a bit personal, so for brands without faces that don't have a lot of events, it can be difficult to be appealing. I like it because my posts reach the targets and it can be random or whatever, but it gets your name out. I wouldn't use it for an enterprise business. The downside is lots of unwarranted nudity and pointless conversations you don't feel like having. Some people will treat you like their personal boyfriend/girlfriend but you can usually just respond less often and they'll slow their roll.
I'd like to know more about other's Snapchat strategies.
