OK, I kinda thought that’s how someone had probably done the math. That’s pretty sloppy. I would be shocked if the “average” American Facebook profile made them $200/year (note that “average” itself can mean several things, and the way the article does the math is in some ways least like how things really work, in a way most humans would relate to).
But then again, I’m sure I make a lot of ad impressions per year on FB, even if I have mostly blocked out (mentally) internet advertisements. I do not use an ad-blocker, because until a few days ago I’ve been in the M&E space for many years, and you know.
Just look at online ad CPMs, and see if that makes any sense.
