May 2011 social networking data from US is in from Experian Hitwise. I updated our social networking market share data with th latest information and it now spans from March 2008 to May 2011.
Facebooks growth is slowing down and this is true specially in its US core market. This is to be expected as Facebook stabilizes and becomes a mainstream site in US market. In May Facebook lost almost 1 percentage point of visits dropping from 64.35% to 63.46%. But do not fear for Facebook as it still commands more than half of all US population. Check out our infographic: 50% of US Population on Facebook.
YouTube gained 0.56 percentage points moving to 20.50 percent of visits from 19.94 in April.
In May we got a new number three and four. After agonizing decline MySpace finally dropped from third place to fifth with only 1.06 percent remaining from its once dominant market share. This “once” was mere two years ago In May 2009.
Drum roll please, the new number three is Twitter with 1.15 percent by market share of visits. To get to this position Twitter had to pass Yahoo! Answers which lost ground in May.
Now the top 3 social networking sites by market share of visits match our perception:
Last month LinkedIn’s marketshare moved slightly upto 0.39 percent as its stock price dropped about 25% from the first day of public trading.
The chart below is in logarithmic scale so that the smaller sites wouldn’t just a single line around 1% of social network market share. Every month in the chart lists the top 10 sites of that time by the market share of visits. Please note that it is just a percentage and 30% in January 2009 is a lot less than 30% in September 2010. The gaps in the the lines mean that the site wasn’t in the top 10 at that time.
