Since December, views on YouTube have dropped 28%, and March views are only slightly above what they were a year ago, startling for a site accustomed to breakneck growth.

It’s an intended consequence of the Google-owned site’s shift from a video search engine filled with snack-size content to a full-fledged, couch-potato-optimized entertainment destination. At YouTube, the “view” is out and “engagement” is in.

After investing $100 million to create content channels, YouTube’s focus has shifted from directing viewers to videos of skateboarding dogs to enticing them into longer, more engaging videos—the kind that are, not incidentally, more appealing to advertisers.

On March 15, YouTube altered its recommendation system to make the time spent with a video or channel a stronger indicator than a click in determining which videos to surface to a user.

“Our goal is we want users to watch more and click less,” said Cristos Goodrow, a former Google search executive who joined YouTube as director of engineering a year ago. “This is better for users because it takes less clicking to get to the video you want to watch.”

Like Google, YouTube is an empire built on clicks, and it has used them above all else as a proxy for popularity and — in a sense — quality. Over the years the site has gotten very good at using data about which videos were getting clicks, or views, to serve up recommendations and get users to click on another video.
