An introduction to Twitter Cards

Because of the 140 character limit on Twitter, Twitter Cards allow you to share rich media experiences, like being able to sign up for a mailing list, watch a YouTube video or click on an image in Twitter, right from your Twitter timeline. These pieces of extra media are created by adding a few small lines of HTML to your website and then any user who Tweets a link to your website will have a "Card" added to their Tweet with extra media. Here are a few examples of how Twitter Cards might look once they've been published:

Twitter Cards would need to be directly implemented by the website owners within the HTML. If you're sharing a link to a website where Twitter Cards have been implemented, then this should work great once your Tweet has been published. However, if you're sharing a link to a website where Twitter Cards have not been implemented, unfortunately this wouldn’t work. Twitter has a bit more information on how to implement Cards here. In addition, we put together our own guide on getting your website set up with Twitter Cards here.
