Metro traffic in August was up 16.35 per cent on July. Mirror Group Digital reported a rise of 15.67 per cent.
Metro attributes its significant rise to a growth in mobile traffic. In December Metro launched a responsive site, later creating 'web editions' so readers could swipe though articles on a smartphone.
A release from Metro states mobile traffic is up 143 per cent since the start of the year following the re-launch. According to Metro, 58 per cent of UK traffic now comes from mobile.
Last month Metro.co.uk reached 12.7 million global monthly unique users, 6.18 million of those were views on mobile devices. Mobile stats show a year-on-year growth of 104 per cent and 143 per cent growth since January, the statement explains.
"Internal figures suggest we’re on track to challenge this record next month," said Linda Grant, managing director at Metro.
Mirror Group Digital had 34.4 million unique users in August – a year-on-year increase of 103 per cent.
Traffic to the Telegraph grew month-on-month by 11.05 per cent to 60.4 million uniques, a rise of 11.94 per cent year-on-year.
Mail Online's rise continued, with a 2.57 per cent increase in August month-on-month. The site had 137.7 million visitors in August, 45.5 million of those from the UK. August marked exactly a year since traffic rose above 100 million visitors a month for the first time.
Traffic to the Guardian was down slightly in August, a drop of 1.56 per cent month-on-month to 83.5 million visitors.
