After tweeting its intent to go public back in September, Twitter officially revealed its S-1 paperwork yesterday. The company said it will sell shares under the name TWTR and is initially seeking $1 billion.

According to its filings, Twitter has more than 215 million monthly active users and 100 million daily active users resulting in 500 million tweets every day. It’s worth noting that nearly 75 percent of its monthly active users come from mobile devices, and about 65 percent of its ad revenue comes from there as well.

In terms of advertising, Twitter said it generated 85 percent and 87 percent of its revenue from advertising in 2012 and the six months ended June 30, 2013, respectively. The company currently offers advertisers several ways to help generate traffic and revenue for the platform, primarily through the sale of its Promoted Products: Promoted Tweets, Promoted Accounts, and Promoted Trends.

Other noteworthy statistics from the filing include the more than six million websites that have integrated with Twitter, as well as the three million applications registered by developers. You can read more details from the filing on the SEC’s website.

Over the past year, Twitter has made an effort to show that it’s more than just a 140-character chat service. Not only has the company worked to improve its internal offerings — such as the rollout of a better recommendation system — it’s not afraid to experiment with products that help its core audience.

It’s not yet clear what an IPO will mean for the brands using Twitter, but with advertising and mobile contributing as they are, it’s fair to assume that we’ll see more features that play well with those strengths.
