See who has looked at your cool stuff

In this day and age where we create site collections instead of sub sites it’s quite easy to see who has taken an interest in your stuff.

Header over to https://tenant.sharepoint.com/sites/yoursite/_catalogs/users/simple.aspx and view the contents of the hidden User Information List. This list contains an entry for anyone who has ever visited your site.

And a shout out to Tobias Zimmergren and his trusty old post from 2008 covering this http://zimmergren.net/technical/sharepoints-hidden-user-list-user-information-list.
