Best Practices

Videos with a length of 6 or 15s typically see a higher completion rate, but the unit can hold up to 30s of video content.

We suggest using as little text as possible to allow your branding and imagery to shine. Keep copy as close to the following suggestions:

  • Headline (100 characters)
  • Additional copy (100 characters)

If you would like to include more text than suggested, consider animating to break up the content and allow the user to process smaller pieces of information, always ending with the CTA.

We recommend a CTA with no more than 20 characters and to keep the CTA visible at all times so the user is encouraged to click through.

Our creative team can resize from an existing 300×600 standard banner PSD.
