There are two different ways to access your individual content level statistics: through your Publication List, or via Account Level Statistics.
A. You can view the statistics of particular content through the Publication List.
In the top right menu go to PUBLISH, select Publisher Dashboard and go to PUBLICATION LIST.
Locate the document whose statistics you want to view and click on STATISTICS.
From here you will be able to view the content statistics.
B. If you are on a Premium or Optimum plan, you can access the content level statistics also through Account Level Statistics.
Under Account Level Statistics, locate All Publications in the middle of the page. By clicking on particular content you will be able to see its statistics.
