Just noticed today (2017-05-18) that Reddit shows number of page views for your submissions, underneath where you can normally find the number of upvotes.
It applies to both link posts and self/text posts. You can only see the pageviews for your own submissions.
The page views aren't shown (and maybe weren't tracked?) on posts I've submitted more than 20 days ago. Didn't see any subreddit settings specific to showing page views in the moderator's panel.
Thanks for the heads-up.
