Edit Ad Unit. Size Mapping Option Tab.

Size Mapping option used along with Google Ad Manager integration. Use case: Ads will look good on a site whether visitors are using a desktop, tablet, or smartphone. More about this option here: https://support.google.com/admanager/answer/3423562?hl=en

Example:

You can specify that if the browser is larger than 1024x768, then ads sized either 970x90 or 728x90 should serve, whereas for smaller browsers only 468x60 ads should serve. GAM measures the size of the "browser", actually the size of the viewport, and shows appropriate ads for such size. 

To make it work, a user of the HeadBidder platform should enable the option and build several groups or “breakpoints” where each describes a set of ad sizes applicable for current viewport size. Note, that's enough to add only screen width to make all work.

1. Enable/Disable Size Mapping option.

2. This is one “Breakpoint“. For screen sizes wider than 1024 px. GAM will show ads 300x250, 468x60 and 160x600 only. The Breakpoint could be either deleted or edited.

3. The button “Add a Breakpoint“ is used to create a new one, an empty template for new Breakpoint.

4. Default Breakpoint, for screen size greater than 0 might be added using this switch.
