Twitter today announced the Lead Generation Card, which is a new, expandable tweet format that allows users to show their interest in a particular discount or offer that’s being promoted by their favorite brand. When users expand the tweet, they’ll see a description of the offer and a button to send their name, Twitter handle, and email to the brand. All this is sent as soon as the card button is clicked. Twitter has been testing the cards with Full Sail and Priceline, and the iea is to give businesses more opportunities to discover new customers, while simultaneously reducing the amount of time spent between spotting an offer on Twitter and actually paying for the product online. It remains to be seen whether this is exclusively for promoted Tweets, but if it’s used broadly it could mean a very different Twitter for marketers, brands, and companies.
