 The other thing is that we prioritized the right languages. Back then, the four main languages were French, Italian, German, and Spanish (and Chinese, but we are blocked in China). Now look at that list - that’s today’s distribution of languages. Italian isn’t on the list anymore; French and German are about to fall off. In the last year we quadrupled the number of people on Facebook in Hindi. Building for what the world is today is an easy mistake to make, and it’s a lot of what the other social networks did. We built a scalable translation infrastructure that actually enabled us to attack all of the languages, so we could be ready for where the future is going to be. You’ll probably be able to see some of our Internet.org summit in India about where we want to go with language translations.

 These are the tactics I want to go through now: Virality, SEO, ESPN, SEM, Affiliates/referral programs. I think there are two ways to look at virality. There’s a great book by Adam L. Penenberg called the Viral Loop that goes through a bunch of case studies of companies that have grown through viral marketing. I strongly encourage you to read this book if you’re interested in viral marketing, as well as advertising. I think Ogilvy on Advertising is great as well because in the chapter 7 you can't think of anything else stick a car to billboard with super glue and people will buy the super glue. He has some really great creative tips. So virality. Sean Parker has this really great model that he told us about when I joined Facebook, which is to think about virality about a product, in terms of three things. First, is payload - so how many people can you hit with any given viral blast. Second, is conversion rate, and third is frequency. This gives you a fundamental idea of how viral a product is.
 
 Hotmail is the canonical example of brilliant viral marketing. Back when Hotmail launched, there were a bunch of mail companies that had been funded and were throwing huge amounts of money at traditional advertising. Back in that time, people couldn’t get free email clients; they had to be tied to their ISP. Hotmail and a couple other companies launched, and their clients were available wherever you went. You could log-in via library internet or school internet, and be able to get access to that. It was a really big value proposition for anyone who wanted to access it. Most of the companies went out there and did big TV campaigns, billboard campaigns, or newspaper campaigns; however, the Hotmail team didn’t have much funding as they did, so they had to scramble around to figure out how to do it. What they did was add that little link at the bottom of every email that said, ‘Sent from Hotmail. Get your free email here.’
