If the banner has animation, the animation must be activated only when the reader
sees the banner in full.
If the banner has a video, the "in-view" setting should be selected.
The preventPageSwipe: false setting must be selected for banners that qualify as a
cube type based on their attributes. This allows the reader to navigate the page
comfortably and prevents inconvenience when the banner rotates in different
directions and the page does not move up or down.
All video ads must automatically start without sound on all devices.
The button to deactivate the banner must be clearly visible and easy to press. The
minimum size of such a button is 16x16px, 24x24px. Smaller than 16x16px is
considered poorly visible.
The edges of the banner cannot be transparent. Also, the entire area of the banner
that can be clicked by the user must be clearly visible.
Expandable banners must have an off button: both expanded and smaller versions.
Video advertisement (preroll) can be played from 3rd party codes only if the
buttons: "Skip advertisement" (skip) and "Mute" (mute) are working properly. If the
mentioned buttons don't work and the client can't fix it (we don't see the client
settings), then the physical file is allowed.
