General Guidelines

  • Site reserves the right of final approval on creative assets.
  • The advertising content must be clearly identifiable as an advertisement, as opposed to a link within site content. Advertisers must be clearly identified by name in at least one frame of the advertising content.
  • Ad units that have a white or partially white background must be bound by a visible one (1) pixel non-white box built into the graphic. Creative must still meet size specifications with border.
  • All advertisers must have a privacy policy, no more than (one) 1 click from the linking page to the Ad unit.
  • Ad units must have a linking URL that resolves to an active page.
  • All linking URLs must open in a new window.
  • Placeholder or non-final ad content will not be considered as “proxies” for final creative.
  • ABC OTV’s ad server, Google Ad Manager, is IAB compliantSAS-70 certified, and Media Rating Council (MRC) accredited.
