Ad Group Widget
The Ad Group widget allows you to rotate through many ads an Ad Group into a widgetized area of your site.
There are a few configurations available to the Ad Group widget. You can title the ad group, select the group that you'd like to be displayed in the widget, choose how many ads from the group are to be displayed at the same time, and set the number of columns that you'd like the group to be displayed in (fig. 1).
This allows you to present your ad groups in a variety of ways. Here is an example of displaying four ads from a group in one column (fig. 2).
Note: your theme may require you to specify a title for your widget areas in order for the ads to display properly. If you're running into an ad display issue with a widget, try setting a title for the widget if you don't already have one set.
