    Before you start creating a video

    • The video must not contain vulgarisms or other unethical elements.
    • The video must not exceed the permitted data limits and must have the correct dimensions for the required position.
    • The video must in no way interfere with the page or influence the behavior of page elements which are not a part of the advertising surfaces (video). It must not change the page title or its main content, or arbitrarily adjust the entered URL without clicking on the video.
    • All versions of the video and target URL addresses must be submitted at least two business days before the start of the campaign, if not stated otherwise.

    For secure pages (https://) must all third-party measuring and display codes use only https://. In banner must all other calls and tracking URLs also use secured connection (https://). Only part, which need not be SSL compliant is URL clickthru. Differences in tracking code statistics without https:// will not be taken into account.
