The Atlantic:

You don’t have to spend more than 10 minutes talking to a purveyor of content on the web to realize that the question keeping them up at night is how to improve the performance of their stories against some engagement metric. And it’s easy enough to see the logical consequence of this incentive: At the bottom of article pages on nearly every major content site is an “Around the Web” widget powered either by Outbrain or Taboola. These widgets are aggressively optimized for clicks. (People do, in fact, click on that stuff. I click on that stuff.) And you can see that it’s mostly sexy, sexist, and sensationalist garbage. The more you let engagement metrics drive editorial, the more your site will look like a Taboola widget. That’s the drain it all circles toward.
