When you have enabled Banner Advertising, you will see an additional widget for the module in the list of widgets available in the Page Builder Toolbar.
To configure a panel to be displayed for a custom page, select and drag the widget to the Page Builder Canvas.
In the Cell Tools menu, select the ad panel to display on this page from the list of ad panels created on the Banner Ads Management screen. Ad panels must be configured before adding a panel to a custom page. Next, select the display type: one ad per page load or scrolling ads. One ad per page load will show the user one ad each time they navigate to a new page on your website. Scrolling ads will display all ads in a scrolling format; when a user hovers over an ad, the scrolling will stop, and the user can click on the ad.
