Ad Specs

Pre-Roll CTA

Marry Pre-Roll with a highly effective, traffic-driving Call-to-Action (CTA). The CTA appears shortly after the video starts and runs through the ad’s duration so viewers can learn more about your brand at any time:

  • The tune-in CTA message supports 45 characters of text or less (including spaces). The font type is non-modifiable.
  • Opacity: 60% for background, 100% for text
  • Position: Top or bottom
  • No animation


Viewer Experience

  • A :15 or :30 Pre-Roll begins play.
  • An overlay with text displays for the duration of the Pre-Roll video.
  • The overlay displays "Click Here," or a customizable message up to 45 characters with spaces.
  • Clicking on the overlay or the video launches an external URL in a new browser window.

  • If using DART, standard DART tracking tags and click commands are preferred. If using a different vendor, please contact your Tremor Video Account Manager for details. iFrame, iLayer, JavaScript, or internal redirect tags are not accepted.
