For a detailed view use interactive chart at the bottom of this post.
Twitter has reached 1.82% of market share of visits. This is the highest percentage of market share for them, ever. It seems that Twitter has reached a tipping point and the growth will continue for some time. Twitter has posted 8 months of solid growth and the trend seems to continue. However, summer months may curb the usage a little bit but the same applies to other social networking sites, so market shares should stay the same.
Google+ continues to move upwards. Reaching a new high of 0.63% of market share in US. Google is is integrating Plus into all aspects of their services and the dominant position in search will help them make their social networking service slowly expand. People will not choose to use it but they will do that as a part of other Google services.
Pinterest is continuing down. Pinterest market share of visits fell to 0.85 from 0.92% in March 2012. Seems that the people who are already there are continuing to pin happily but the growth of the site from new users has stalled. Maybe it’s time to make the site open to everybody. In Google+’s case it helped to get attention and new users.
One interesting development is that MySpace, once a king of social media, has been gaining market share for the last 2 months. MySpace went from 0.39% in March to 0.46% in May 2012. I wonder if they have something that will make the site relevant to the masses again.
Other sites: LinkedIn and Yelp are both down a bit with 0.76 and 0.35 percent respectively. LinkedIn might see further decline during the summer months when northern hemisphere is having vacations.
It would be interesting to see the market share changes during the summer months. Sites with strong mobile usage should gain over the others as users leave offices and desktops at home.
Percentages for the big players in May:
Facebook 62.94% (-)
Youtube 20.14% (-)
Twitter 1.82% (+)
About this chart
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.
