This year at f8, Facebook announced AppLinks, a solution to link from app-to-app easily. This essentially gave marketers and developers a way around the browser, instead going straight from one app to another. Today, Facebook has announced that developers have enabled more than one billion unique deep links with App Links.
This means that users can now deep link to more than one billion locations from their apps, a feature that many prominent apps have taken advantage of. Now, partners like Live Nation, Vimeo, Spotify, Mailbox, Quip, Redfin and Goodreads have taken advantage of this linking.
Additionally, Facebook has created a new app back button that allows apps like Redfin to help people go back and forth from one app to another. For more information head on over to AppLinks.
