Users may interact by clicking on the ad, and/or rolling over an ad (or a portion of an ad). With respect to user initiation for the purposes of these guidelines, a roll-over is defined as a willful pause of the user s cursor on the target portion of the creative (the hot spot ), such pause lasting at least 1-second in duration, before an action may be initiated by the ad (i.e. trigger an expand, etc.). This pause/ delay prevents unwanted user-initiated actions, and false reporting of user engagement. Expandable banners must retract on mouse-off or click to "Close" or "X". Click initiation controls must be no smaller than 8pt font (11px) and no larger than 16pt font (21px). Audio must be user-initiated (on click: mute/ un-mute); default state is muted Video must include: Play, Pause, Mute (volume control to zero (0) output may be included instead of or in addition to Mute control) Percentage of CPU usage is based on the Publisher defined benchmark end user-cpu for its audience.

When designing a high resolution ad be selective as to what assets need to be high resolution to ensure optimal image quality. It is also important to limit the amount of external calls that are made. It is recommended that rich media ad s with multiple panels/pages be loaded progressively when available. Only interactions that are available from the initial panel/page should be loaded at that time. As the user navigates through the ad experience, additional panels and animation may be loaded.
