Payments startup Ribbon, which enables purchases on social media sites, is launching new Twitter and YouTube platforms. On Twitter the service takes full advantage of the expanded Cards feature— users simply click on a “Buy Now” button and then input credit card information all within Twitter. On YouTube, the integration comes via in-video annotations, which allow you to click to purchase on a Ribbon checkout page. The conventional wisdom is that conversion rates are highest when you don’t have to leave a site to purchase, so expect Ribbon to create great opportunities for brands.
