Facebook’s huge mobile Q1: 751M users, 30% of ad revenue coming from mobile

It looks like Facebook’s huge mobile risk is turning into a huge mobile opportunity.

The social network reported astounding mobile growth today, with 750 million monthly active users on mobile devices (a 54 percent increase from last year). That’s a significant chunk of the 1.1 billion monthly users Facebook saw during the quarter.

Even better, Facebook reported ad revenues of $1.25 billion for the quarter (up 43 percent form last year), 30 percent of which came from mobile ads. That’s around $375 million in revenues from mobile ads alone. Not bad for a company that was previously worried about its capability to make a buck on mobile.

Facebook also noted that 189 million people only accessed it on mobile devices. It’s hard to read much into that number now, but this shows a significant amount of reach for Facebook with young people who don’t spend as much time on computers (or people without access to computers in general).

It’ll be interesting to see how the launch of Facebook Home last month will affect Facebook’s mobile performance going forward. Right now Home is only available on select Android devices, but as it reaches more phones and countries, it could have a big impact on mobile ad revenue (since it’s basically making Facebook’s ads a part of your phone’s home screen).
