Facebook's newest call to action test: Buy

Facebook has been expanding its call to action options, but the one released today might be its most popular.

Facebook is testing a way users can directly buy a product without leaving Facebook, clicking a “buy” button right on the ad. This will be available on both desktop and mobile, among the advertisers in the test group.

Facebook announced this feature in a blog post:

We’ve built this feature with privacy in mind, and have taken steps to help make the payment experience safe and secure.
