General Display Best Practices

The following specifications apply to all display ads:

  • Creative images must be clear, recognizable, and relevant.

  • Text appearing in the ad must be legible.

  • Creatives must occupy the entire space of the image size you've chosen.

  • Creatives cannot appear sideways or upside down.

  • Creatives cannot be segmented, contain multiple copies of themselves within the ad, or otherwise appear to be more than one ad.

  • Creatives with partially black or white backgrounds must include a visible border of a contrasting color to the majority background color of the ad.

  • Creative file size is recommended to be 150 KB or smaller — this applies to both first- and third-party ads.

  • Creatives must open a new page on click; they cannot open in the same page.

  • Animated ads are restricted to a maximum of 15 seconds of looping, after which point they must remain static.

  • Flash creatives must use the clickTAG function on the topmost layer and must have the stop(); function on the last frame of the animation. A first-party optional back-up static image is supported.

  • In-banner video creatives can be in flash or HTML5 format with a 50 KB maximum file load and a 2 MB load for the secondary file

  • There is no length limit for click-to-start video ads, but the video should immediately go to the landing page upon completion.

  • For auto-start video ads, there is a 15-second limit. Audio should not be heard unless initiated by a mouse-over. Video should be backstopped by a static 300x250 that should click through to a landing page.

  • All in-banner video ads must include the play, pause, mute, and unmute controls.
