CHART OF THE DAY: Twitter Is Having A Hard Time Attracting New Users

Twitter reported earnings for its fiscal third quarter of 2014 on Monday. Revenue, earnings per share, and even monthly active users (MAUs) fell right in line with Wall Street expectations. There was no grand surprise, and the company's stock tanked roughly 9% after the announcement.

Twitter's monthly active users are arguably the company's most scrutinized metric, since everyone cares about how Twitter plans to regularly attract new users. But while membership rises each quarter, the growth of MAUs on the network continues to slow down. According to Twitter's data charted for us by BI Intelligence, Twitter reported 284 million MAUs in Q3 - up from 271 million in Q2 - but year-over-year growth is down to around 21% this quarter, whereas growth in the year-ago quarter was just shy of 38%.

Twitter has been trying new things like "buy" buttons to increase user engagement, but this slowdown in MAU growth was somewhat expected. Business Insider's Jim Edwards predicted earlier this year that the "temporary uptick" in MAUs was likely due to the World Cup, and that Twitter would likely have trouble figuring out how to keep that growth going through Q3 and Q4. Twitter needs another World Cup-size event, or some kind of new incentive, to drive more users to the real-time sharing network.
