Twitter and LinkedIn use different metrics to report activity on their sites, measuring monthly active users (MAUs) and monthly unique visitors (MUVs), respectively. This makes user growth comparisons between the two social networks difficult.
However, comScore tracked MUVs in the U.S. for a number of top Web properties, including Twitter and LinkedIn, and from this, we can get a sense of how their traffic (from those ages 18 and older) stacks up against one another:
- LinkedIn had 63.4 million adult MUVs from the U.S. in September 2013, an increase of 35% from one year ago.
- Twitter had 62.6 million adult MUVs from the U.S. in September 2013, an increase of 10% from one year ago.
So not only has LinkedIn surpassed Twitter for unique visitor traffic among adults in the U.S., but it is also growing at a much faster rate.
Keep in mind, comScore’s focus on Internet users ages 18 and older does not play to Twitter’s strengths. Twitter is favored by younger users, whereas LinkedIn is primarily used by adults.
