Anyone that knows me, knows that my personal engagement with Facebook has wained over the last few years as the social media giant has grown into a giant ad revenue giant. The video below from Veritasium has drawn almost a million views in the last two days. Why? because it punches a gaping hole in Facebook’s pay for “Likes” system and the way Facebook’s pay to play promotions work. If you are a marketer, advertiser, or anyone that uses Facebook as a platform to engage with your target audience, you should watch this. What Veritasium points out is hard to deny, and the point they make about audience engagement effects you more than you know.
