The State Of The Twittersphere (HubSpot Edition)

How many followers do most people really have on Twitter? The average number of both followers and other members people on Twitter are following is about 70, according to the State of the Twittersphere, a new report by Web marketing startup HubSpot. (Full report embedded below). But that average is skewed by elite Twitterers who have hundreds or thousands of followers. The vast majority of people on Twitter use it to keep in touch with a much smaller circle of friends and peers. For those with 50 or fewer followers (three quarters of all users), the average number of followers is 15.6 and the average number of people they are following is 18.4.

HubSpot’s State of the Twittersphere report is inspired by Technorati’s State of the Blogosphere, which tries to quantify trends across all the blogs it tracks. HubSpot gets its data from Twitter Grader, a site it operates that generates a grade for Twitter users based on factors such as how many followers they have, the reach of the people who are following them, and how often they post updates.

Twitter Grader is basically a vanity search site for Twitter, but it has managed to compile data on over 500,000 Twitter accounts, which is probably around 10 percent of the total. It is not clear how representative these users are, but it is a large sample and they certainly are not all power users. (Three percent had 0 followers, 9 percent didn’t follow anyone else, and 22 percent had five or fewer followers). Until Twitter releases its own State of the Twittersphere report, this is as good as the data gets.

Some other key stats from the report:

—70% of Twitter users joined in 2008
—20% of Twitter users have joined in the past 60 days
—The average user has been on Twitter 275 days

So it is pretty much all newbies, and mainstream adoption is just getting started.

—The most popular days of the week to Tweet are Wednesday and Thursday
—An estimated 5,000 to 10,000 new accounts are registered each day.
—Only 5 percent of all Twitter users have more than 250 followers.
—Only 0.8 percent have more than 1,000
—22 percent have five or fewer followers
—Another 24 percent (the largest group) have between 11 and 25 followers

Similarly, most people don’t follow more than 25 other people. In fact, 30 percent follow the Tweets of five or fewer other members. Again, 11 to 25 seems to be a sweet spot, with 21 percent users following that many others. Here’s is the breakdown:
