Twitter Cards provide a savvy way for content to be displayed to users, providing, for example, a title, content snippet, and thumbnail in a clean card-like format. Back in December, Pinterest rolled out support for Twitter Cards, while some others, such as Instagram, have backed away from the feature. Now the microblogging service has announced the addition of three new Card types, in addition to deep-linking for apps.
The new Card types are App, Product, and Gallery, each of which is mostly self-explanatory. The App Card type provides app information, such as its name and icon, description, and some other relevant data, including its price. The information is provided via the App Store or Play Store, and all that is required of developers is their ID. Similar to this is the Product Card type, which shows a product's image, description, and a maximum of two fields that can be customized with other details, such as pricing.
Finally, there's the Gallery Card type, which is used when there's more than one image available, making that obvious by including more than one image in the card and providing a notification that there's a gallery to be seen, rather than just one or a couple images. These expand on the photo, summary, and video Cards, and are said to provide a foundation for future cards.
According to the announcement, there is already a substantial lineup of partners that will take advantage of the cards, including Etsy, Jawbone, Angry Birds, SoundCloud, Vine, Foursquare, and more. In addition to the cards, Twitter has also unveiled deep-linking for mobile apps, which you can see in the image above. Enabling this can help drive app downloads.
