May was a busy month for Facebook and our Android developer community. We had a great time meeting many of you at AnDevCon Boston and at our Kickoff Party at Google I/O.
This month, we're out and about again at developer conferences around the world. Meet us at:
Mobile DevCon: LATAM: Buenos Aires, June 3-4; Santiago, June 6-7. Mobile DevCon: LATAM is a community-run series of conferences in Argentina and Chile covering the latest in mobile and social app development. Developer advocates Luz Caballero and Prashant Sridharan will cover the latest Facebook mobile SDKs, and will host office hours for developers using Facebook to come and work through code-level issues in their apps.
Le Web: London, June 5-6. Le Web is a European conference about innovation and entrepreneurship on the web. Join Julien Codorniou, our Head of European Platform Partnerships, for a panel discussion called "Ruling the App Store" to learn how to drive installation, engagement and monetization of mobile apps.
Selenium Conference: Boston, June 10-12. The Selenium Conference brings together developers in the Selenium community to discuss the future of testing. Facebook engineer Damien Sereni will be speaking about how we use Selenium for automated testing in our twice-daily release process. His talk will focus on how we encouraged engineers to write good tests, how we keep the test quality high and how we use the tests during the release. He’ll also share some of the new tools we’re building for mobile testing.
Parse Drinkup at WWDC: San Francisco, June 12. Join the Parse team for a lively event at the W San Francisco Hotel, featuring talks from some of our favorite partners and friends, an open bar, snacks, video games, music, and a few surprises. We're excited to chat with you about what you're building, and if you really love what we are working on, come talk to our talent team.
We're looking forward to meeting some of you this June. You can learn where we'll be in future months by checking out our calendar on Lanyrd.
People love sharing news articles with their friends. According a recent SimpleReach study, 23% of external traffic to news publishers comes from social networks. Facebook is the top source of social referrals:

Facebook's role in distributing news content is growing. According to a Pew Research study, Facebook traffic to major news websites more than doubled from 2011 to 2012. We've seen this growth continue, with our data showing overall external referrals up more than 50% in 2013.
We regularly work with news publishers to help them enable people to explicitly choose the news-related content that they share with friends. Below, we've highlighted three steps that news publishers can take to drive social referrals while giving their readers control over sharing on Facebook.
The Like Button and Share Dialog are simple to integrate into your website yet extremely powerful. The Like button allows readers to show interest in articles with one click, while the Share Dialog lets them add their own commentary before posting articles to Facebook.

By adding both Like and Share to their website, Slate.com doubled its Facebook referral traffic between the second quarter of 2012 and the first quarter of 2013
According to Pew Research, 47% of mobile users get news through social networks on a regular basis. To take advantage of this trend, we’ve introduced a new Share Dialog for iOS apps. Our redesigned dialog lets readers share links without requiring Facebook Login. The dialog will also be available for Android soon.

Our new iOS Share Dialog is easy to integrate, doesn't require Login, and lets people tag friends for additional distribution and context
According to SimpleReach, 67% of social referrals came from just 1% of articles. We’ve found that stories with attention catching headlines, large images, and detailed descriptions perform exceptionally well on Facebook.

Testing multiple headlines for each article helped Upworthy.com grow to 10 million unique visitors in one year
Pages are a great way for news publishers to share stories and create an ongoing dialog with readers. Provide unique, visual content in your Page posts and seek feedback using comments. Use Page Insights to learn what content your audience cares about the most and iterate.

Metro.co.uk posts links with teaser content on their Page to entice readers to click through to the website
To help news publishers understand how to get the most value from Facebook, we recently launched a new Facebook media portal with links to best practices guides and case studies. Please check these resources out below. We’ll continue to work with publishers on new ways to facilitate news discovery for the more than 1.1 billion people who use Facebook.
In April and May we hosted over 1000 iOS, Android and Mobile Web developers in New York, London and Seoul for Mobile DevCon 2013.
Over the last year, we've been hard at work improving our Platform for mobile developers. Now, more than 81% of top 100 grossing iOS apps and 70% of top 100 grossing Android apps integrate with Facebook.
At Mobile DevCon we announced further improvements:
We also announced the Facebook Technology Partners program, open-sourced our iOS and Android build tools: Buck and xctool, and released new targeting options for Mobile App Install Ads.
For those who couldn't attend, we recorded many of the talks, and have posted the slides from every session online for you to download. To view the videos and download all the slides, visit the event pages for New York, London or Seoul. These videos - and more - are also available on the Facebook Developers YouTube Channel.
Here's a summary of a few of the sessions:
Doug Purdy, Director of Platform Products, talks about the challenges mobile developers face getting discovered amongst the 700,000 apps in both Google Play and the Apple App Store and how, with 751 million active users on mobile, Facebook is the top driver of awareness for new mobile apps.
With over 1 billion Open Graph actions shared on Facebook every day, Rose Yao explains how Open Graph can help your users tell the story of their lives through your app, and how - with collections - your app can become part of a user's Timeline.
Previously, Open Graph required developers to host web pages for their objects. Eddie O'Neil explains how the new Object API and the Native Share Dialog make it easy for native mobile developers to integrate Open Graph into their apps.
With 751 million monthly mobile users, Mobile App Install Ads and Mobile Sponsored Stories are great ways to drive awareness of your app at scale. Paul Bain shows you how to get started with promoting your app on Facebook and how to optimize your targeting and purchasing strategy.
The best Facebook integrations make it really easy for users to Login and share stories back to Facebook with Open Graph. In these three sessions, Prashant Sridharan and Connor Treacy take you through how to best implement Facebook's Mobile SDKs - including code-level tips and some best practices.
The Object API releases mobile developers from needing to have a web server to host your Open Graph objects. In this talk, Christine Abernathy shows you how to use the Object API to integrate Open Graph into your native mobile apps.
Facebook is one of the most downloaded iOS and Android apps of all time. In the last year, we transitioned both apps from HTML5 to native Objective C and Java. But this transition meant we had to retrain our engineers, develop new tools and rethink our processes. Engineers from our core mobile team, Adam Ernst and Michael Bolin in New York and Simon Stewart and Alan Cannistraro in London talk through this transition, and how we ship improvements to our apps every single month.

We really enjoyed connecting with the developer community at the three Mobile DevCon events. We heard some great feedback about our products which are helping shape the future of our roadmap. We look forward to meeting you at one of our future developer events.

Since last Wednesday's update, we showcased an improved share dialog on iOS that offers a lightweight and consistent way to enable sharing from your apps.
