The national newspaper sites of six of largest UK newspaper groups attracted about 95 million visitors in June, according to a new report published by the Newspaper Marketing Agency.

The report aggregated the Web traffic of the 16 national publications owned by its members, Media Guardian reported.

NMA's members include Associated Newspapers, Independent News & Media, Mirror Group Newspapers, News International, Telegraph Media Group and Guardian News & Media.

Those British online national newspaper Web sites attracted 94.8 million unique visitors in June, while 35.5 million of them were UK readers, Media Guardian reported.

In terms of overall time spent on these sites, more than 715 million minutes were consumed in June.

If the data is de-duplicated, which means a visitor to multiple Web sites was counted only once, only 66.1 million global unique visitors visited NPA member national newspaper sites, and 19.6 million of them came from the United Kingdom.

This showed that two-thirds of overseas online visitors surfed on only one site in June, while about half of British readers visited a single site only, Media Guardian reported.

Google is the leading online traffic referrer to UK national newspaper Web sites, drawing about 33 million unique visitors. Direct traffic, which means people directly inputing a newspaper Web address or using a favourite link, is ranked second, contributing another 22 million visitors.

The report also found that 95 of the top 100 search keywords leading to the newspaper sites are the names of the publications, Web address or some feature of the Web site, according to Media Guardian.
