Twitter: All the Numbers That Matter
Twiiter, at its first-ever developers conference — known as Chirp — which is being held in San Francisco had its co-founders Biz Stone and Evan Williams provided some hard numbers behind the growth and size of the social network. Here are some of the most important ones we’ve collected so far:
105,779,710 registered users
3 billion API calls a day
175 employees
600 million searches per day
300,000 new users per day
180 million unique visitors per month
37 percent of active users use Twitter on their phones
75 percent of traffic comes from outside Twitter.com
100,000 registered applications

180mm unique visitors a month , how are they defining unique?
I’m afraid I don’t know that, Bob. If I get a chance I will ask.
Mathew, if you have the opportunity you should question those “600 million searches per day”. That number seems to be way off. It would put Twitter ahead of Bing and Yahoo and neck-and-neck with Google. So, how’s that possible?
Compete says that search.twitter.com has just about 2.9M unique visitors per day.
Marcelo, the 600 million figure includes every search that comes through the Twitter index, and the vast majority of those come from third-party apps and services. Twitter also explained that this number includes Twitter widgets that display and update tweets, etc. Danny Sullivan has a good look at the issue here: http://searchengineland.com/twitter-does-19-billion-searches-per-month-39988
A number which would be interesting to get is the number of daily active users, the number of automated posts (which I believe is more than 50% of the active users).
@Marcelo – compete.com has shown to be way off, but yes it’d be interesting to know if they consider API-based visitors among the unique visitors. If so, that would explain why the numbers are way off.
