Since launching their timeline app in January, digital reading platform Kobo has seen its traffic from Facebook grow by more than 50 percent. In addition, the company is reporting that a 90 percent increase in daily registrations.

Kobo used Open Graph, which lets developers turn a web page into a rich object in a social graph, to implement the timeline.

Kobo developer Bryant Lee explained the implementation process in a Facebook Developers blog post. He wrote: “Kobo defined Open Graph actions for some of the most conversational aspects of reading a book – such as beginning and finishing a book – to encourage sharing and stimulate discussions with friends. Kobo provides detailed controls for people to manage what stories are shared to Facebook.”
