According to comScore, Twitter reached 91.5 mn* monthly unique visitors in March, up +216% yoy, which implies 1Q average monthly uniques of 59.2 mn (+95% yoy vs. 4Q growth of +31%). For reference, in February comScore reported 43.2mn monthly mobile uniques (+38% yoy) versus 86.8mn uniques (+177% yoy) under the new methodology which now includes secure connections. On Twitter mobile app traffic alone, uniques reached 34.4mn in March, up +49% yoy, which implies 1Q average mobile app uniques of 33.9mn (+50% yoy vs. 4Q growth of +42%). For reference, the 4Q comScore monthly mobile uniques was 38.3 mn, which compares to Twitter’s disclosed 54.0 mn monthly active users in the US in 4Q, of which 76% or 41.0 mn users accessed from a mobile device.

Earlier this morning I tweeted that “according to @comScore, @Twitter had 91.5 million monthly active users in Mar’14 up +216% yoy vs Feb 2014 43.2mn MAUs.” Actually that was not correct. It was 91.5 million monthly unique visitors and I mixed things up. Apologies for sending that erroneous tweet.
* mn = Million
