Has anyone taken a more dynamic route to placing ads? Example: using leaderboard on top right of page AFTER and ONLY AFTER 10am and BEFORE 12pm? I was playing around with my ad units this morning and after doing such, eCPM rates shot up! Wondering if this could lead to better eCPMs or this was just a fluke accident?
No, I have never done this before, but I did play with rotating different ads throughout the day in the past and seemed to work well for me too.
