With Facebook's organic reach in steady decline, I was curious how engagement stacked up vs YouTube. It turns out the engagement per subscriber is 20x over Facebook likes/
To get this information took a look the top 5 brands from Facebook and YouTube and pulled the rate of comments per post or upload over a one week period. I chose comments as the sole indicator of engagement because comments are apples to apples. There are no dislikes on Facebook (but there are on YouTube, etc).
