In a Facebook developers blog post, Douglas Purdy, talks how mobile games and apps can be grown with Facebook. Regardless "if an app lives on a mobile platform, like iOS or Android, or on Facebook.com, it can plug into Facebook and grow through News Feed, timeline, Requests, Bookmarks, Search, and now the App Center," Purdy posted.
Mobile apps, just like apps on Facebook.com, can benefit from an audience of more than 900 million users, 500 million of whom are active Facebook mobile users.
"Last month, Facebook drove people to iOS apps 134 million times, and to the Apple App Store 83 million times," he said.
"More than 230 million people play games on Facebook.com every month. And, more than 130 games on Facebook have more than 1 million monthly active users each, from King.com (52.3M+ users), to Peak Games (18M+ users), Rovio (17.3M+ users), Playtika (7.2M+ users), Halfbrick (6M+ users), and Kixeye (4.7M+ users)."
By enabling people to log into their apps with Facebook, mobile developers can reach a wider audience, and keep people coming back.
"Once a mobile app integrates with Facebook, people can log into the app in one click, without needing to remember a separate user name and password. Once the mobile app is connected to their Facebook account, users can find friends and share activity (such as scores and achievements) back to Facebook. Additionally, a bookmark will be added on the Facebook mobile app, so it's easy to re-engage," explains Purdy.
For mobile developers, using Facebook for login improves conversion by providing an easy registration process, increases engagement by making it possible for people to connect with friends, and offers distribution through Facebook.
Ending the post, Purdy says they'll continue to build tools that benefit mobile, web, and cross platform developers, to make it easier for people to find social apps, and share them with their friends, wherever they are.
Facebook also launched today the Open Graph built-in follow action. "The follow action makes it easier for people to keep tabs on the stories people tell from within your app in their News Feed, Timeline and through the notifications channel," said Yariv Sadan.
"For example, a person can follow their favorite restaurant critic from within a food review app on Facebook. When a person follows another person, the follower will get an entry in their Recent Activity box. The follower will also see a notification that they followed someone in your app," explains Sadan.
Content a person publishes within your app will be displayed in the follower's News Feed even if they aren't Facebook friends. People can control who sees what they publish through the privacy settings of the app.
Starting today we will no longer approve custom follow actions. Apps that currently use a custom follow action must migrate to use the built-in follow in the next 90 days. "We have updated the Platform Roadmap to reflect this change," he said.
To learn more about using the follow action, see this documentation on built-in follow.
