SAN FRANCISCO, Aug 2 Google Inc's (GOOG.O) new
social network has attracted 25 million users, making it the
fastest website to reach that audience size, according to data
released on Tuesday by comScore SCOR.O.
Google+, launched in late June, had 25 million unique visitors
as of July 24 and is growing at a rate of roughly one million
visitors a day, comScore noted in a presentation.
In contrast, it took Facebook about three years to attract 25
million visitors, while Twitter took just over 30 months,
according to comScore.
While the data show Google's latest attempt at breaking into
social networking has started strongly, it may not mean the
project is a long-term success. MySpace grew to 25 million unique
visitors in less than two years -- faster than Facebook or
Twitter. However, it's lost a lot of visitors in the past year,
comScore data show.
The United States had more than 6 million unique visitors, and
India more than 3.6 million, the data show,
Canada and the UK had around 1 million unique visitors each,
Germany over 920,000 and Brazil just over 780,000. France and
Taiwan each had around 500,000.
