10 méthodes concrètes pour garantir le ROI d'une stratégie Marketin... Facebook Growth & Traction: What are some decisions taken by the "Growth team" at Facebook that helped Facebook reach 500 million users. This question suggests it wants to know the exact, tactical decisions.
As much as I would like to share those tactics in great detail because it's fascinating and readers of this question would find it interesting/valuable, I'm legally bound to a certain amount of confidentiality so I'll only go as detailed as I'm legally able to. That basically means I won't share numbers and I won't comment on things that aren't directly discernable to the general public. Also, the list of optimizations is too long for anyone to remember. I also didn't work on the majority of those optimizations directly but tended to learn about them via close proximity to the people solving the problem they were assigned to solve.
