SelectView Pre-Roll

  • A click tag to track clicks to a destination page
  • 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.

Note: When a third-party serves the ad, user-initiated sound settings cannot be configured by the advertiser; that setting is always configured by the publisher that requests the ad.
