Twitter Cards, which allow brands to attach “media experiences” to Tweets that link to content, launched in June of 2012 and are already being used by more than 10,000 developers.

Yesterday, Twitter announced the availability of three new types of Card, one of which will allow brands to bring users directly to their app via a Tweet.

In what they’re terming as mobile app deep-linking in Cards, users can now tap a link to either view content directly in an app, or be prompted to download the app, depending on whether or not it is already installed.

Here’s an example below, showed an expanded Tweet linking to the Path app.

Twitter has also announced two other Card types – Product and Gallery – meaning that six different Card options are now available to developers, as follows:

  • Summary Card: Default card, including a title, description, thumbnail, and Twitter account attribution
  • Photo Card: A Tweet sized photo card
  • Gallery Card: A Tweet card geared toward highlighting a collection of photos
  • App Card: A Tweet card for providing a profile of an application
  • Player Card: A Tweet sized video/audio/media player card
  • Product Card: A Tweet card to better represent product content

With the arrival of these new Card types, Twitter has “fundamentally re-architected the way Cards are created and delivered”, laying a foundation that they say will make it easier to develop more types of Card in the future whilst being backwards compatible. The new Cards are launching with a number of Twitter partners, including Etsy, Flickr, Foursquare, Path, Rovio’s Angry Birds, SoundCloud and (of course) Vine.
