// Regarding the quality of Facebook traffic:
“On thing we gradually noticed, however, was that maintaining a Facebook page was pretty much a waste of time by the end of 2014. While Facebook sends lots of traffic to us if one of our articles goes viral, posting said article to the Priceonomics Facebook Page does pretty much nothing any more. Posting on Twitter or emailing things to our readers is much more effective for us than posting on Facebook. We can only imagine how swindled companies that spent millions promoting their Facebook pages must feel. What a monumental waste of money.”
