A report from Nielsen finds top websites benefit from the growth of mobile-accessed Internet, reports Brandweek.

Nielsen's study found a major site's audience can increase by an average of 13 percent with the inclusion of mobile-friendly websites.

For niche or specialty sites, growth can be even greater. Weather and entertainment sites saw 22 percent growth. And sites focusing on games or music drew 15 percent more visits.

Coming in below average were web-based email services, whose audiences grew 11 percent; sports sites grew 10 percent; business and finance sites by 4 percent.

At the bottom of the list were shopping sites, which only saw one percent audience growth through mobile sites.

The report came from Nielsen's new TotalWeb unit, which measures Internet audiences across all platforms. The study analyzed the traffic of over 200 sites.
