Player Card


Native to the Twitter platform, the Player Card offer users a one-click experience. It displays high-quality video content and is designed to be shown on a cost-per-view basis, meaning you pay only when someone clicks your video ad.

  • Tweet copy: 140 characters
  • Title (under video): 200 characters
  • Description (under video): 200 characters
  • Media: video
  • Formats accepted: MP4 or .MOV

  • Tweet copy: 140 characters
  • Hashtag: 21 characters
  • Pre-populated user tweet: 116 characters
  • Headline: 23 characters
  • Thank you text: 23 characters

Direct Message Card


An engaging video or image prompts the user to click an automated reply — one of four fully-customizable call to action buttons — which allows a bot to directly interact with the user through their direct message inbox.

Direct Message cards are still in beta, so any advertisers interested in using them should contact a Twitter representative for more information.
