The data suggests that Twitter users demonstrate higher engagement with brands, and not just with tweets they post.
Theories abound for the increased levels of engagement. One is that the basic interface of Twitter means users are not being distracted by other activities such as games and photo tagging, making them more likely to browse away from the site.
The research will be welcomed by chief executive Biz Stone who has yet to find a way to monetise activity on Twitter, instead relying on investment funding.
It emerged last week that Twitter is close to closing a $100 million investment deal which will value the company at $1 billion.
Earlier this week Stone said the company had no plans to begin widely running ads until 2010, but he has mooted plans to introduce corporate accounts for businesses with paid-for analytics features.
