This is a great video I came across that breaks it all down pretty nicely… basically for a lot of you guys out there the “likes” you get when you pay Facebook to get more people to “like” your page are useless. I noticed this with many of my clients starting in early December of last year and advised everyone to stop paying for these.

“When I paid to promote my page I gained 80,000 followers in developing countries who didn’t care about Veritasium (but I wasn’t aware of this at the time). They drove my reach and engagement numbers down, basically rendering the page useless.”

The US Department of State spent $630,000 to acquire 2 million page likes and then realized only 2% were engaged.
