According to the newly released NRS PADD (National Readership Survey Print and Digital Data) report, the Telegraph website had 7.41 million UK readers in September. The Mail Online had 6.89 million and the Guardian site, which changed its domain name in July, had 6.17 million readers in September.
The Mail Online was found by the survey to be the UK newspaper website with the most traffic overall. The web-only stats record people who do not also read the brand in print format.
The report found that the Mail Online had 10.7 million readers in September, the Telegraph website had 9 million readers, and the Guardian was found to have a UK web traffic of 8.3 million.
The report also combines print and website circulation figures, and shows the Daily Mail, Mail on Sunday and Mail Online to have a combined readership of 20.48 million. The Sun had a readership of 17.16 million and the Mirror and Sunday People 12.95 million. The population of the UK is 63.7 million people.
The report is based on comScore data from September 2013 and NRS data from October 2012 to September 2013, split into a monthly average. Data is collected via a range of methods including reader surveys, and duplicates are removed so people who read online and in print are not counted twice.
The Guardian and Telegraph have each held the top spot for quality dailies since the National Readership Survey data started releasing the report in September 2012. More information on how the NRS collects and collates the data is available on the NRS website.
Global figures released by the Audit Bureau of Circulation (ABC) show the Mail Online was the audited newspaper website with the most traffic in September, with 146 million unique browsers. ABC records browser numbers rather than people, so if someone reads a website on a mobile phone and a laptop, that accounts for two unique browsers.
UK figures released earlier this month by UKOM comScore found the Mail Online to have the most UK readers in September. The UKOM comScore report includes mobile, tablet and app figures, unlike today's NRS report which provides desktop viewing stats only.
The UKOM comScore report found that the Telegraph had 9.1 million readers on desktop whereas today's NRS report recorded 7.41 million readers in September.
The NRS PADD report also includes regional newspaper and web stats. The figures show Metro had UK web traffic of 1.59 million in September and a combined print and web circulation of 11.76 million. ABC stats recorded 16.8 million unique browsers globally for Metro, and 7.6 million UK browsers.
Correction: The article originally said the Telegraph was the newspaper website with the most web traffic. This has been corrected to reflect that the news outlet topped the list for web-only traffic. The web-only stats record people who do not also read the brand in print format.
The Mail Online was the newspaper with the highest UK web traffic in September. The article has been amended to explain that and provide stats.
