Google AdSense Ad Balance Feature Will Collapse Unfilled Ad Units

In the beginning of this year, Google AdSense announced a new feature named Ad Balance that lets you controls help you reduce the number of ads you show to users, specifically the ads that earn you the least revenue, and see how it affects your earnings. This is all done via an easy to use slider in the AdSense publisher portal.

Well, sometimes, using this feature would result in unfilled ad slots that loaded blank space. Google updated their post to add that they are now going to be automatically collapsing any ad units that go unfilled.
