Facebook adds call-to-action buttons to Instant Articles

Facebook’s Instant Articles opened up to all publishers nearly a year ago, but the mobile viewing product was very much read-only. Publishers didn’t really have a native way to support converting readers into something more, like subscribers. On Friday, the social media company launched call-to-action units with the goal of providing a “more direct line of communication” between the publisher and the reader.
The call-to-action units are being rolled out starting next week
