Three emotions to manipulate; Fear of missing-out, Time-spent Anxiety, and Anger.

The evil marketing side of me says, bring up a dialog-box;

  "your time is important to us,

  would you like to view a 15-sec sponsor-commercial and return to your-position on the previous page Yes/No"

  'Yes' runs the Spot and returns to the exact position on the previous page.

  'No' either just removes the dialog-box, and/or takes you to the top of the current-page,

  or takes you to a random-page very loosely related to the subject of the previous page.

P.S. Please don't Kill ME!
