In a recent Data Driven Design Q and A session with followers, I was asked, "how can my business build a Facebook Messenger Bot?" 

While it's a great question, if you've never built a Facebook Messenger Bot, or managed a chat bot before, I'd recommend starting by utilizing Facebook Ads' ability to place a Facebook Ad with a Messenger Objective that has the ability to add an automated Bot reply.

This article shows you how to do it, and it's a good place to start, because you can target an audience, spend $15, have a quick automated conversation set up with people who engage with the ad, and see how well it works for your business.
