In a month where coverage of the Olympics would be expected to generate more users than July, Times Online profited most with a 20.1% increase, but the Mail Online surprisingly slipped by 6.6%.
The field was again led by Guardian.co.uk, which added almost 2.5m users from its record figure last month. The 12.1% increase took it to 23.1m.
However, its UK user total showed more anaemic growth, climbing 3.7% to 8.8m. This was characteristic of the whole field of sites, excluding The Sun.
Telegraph.co.uk held on in second place with a 17.7% monthly increase to 22.1m users. However, its UK total actually dropped by 1.4% to 6.3m.
It was overtaken by TimesOnline, which added more than 3m users from July to reach 19.7m. This was an overall increase of 20.1%, while UK users increased 4.4% to 6.16m.
Overall, The Sun was flat, growing user numbers 0.1% to 16m, but within that total the number of UK-based users rose 15.4% to 5.5m.
Independent.co.uk also stayed more or less flat, rising 0.6% to 6.6m; it does not report to ABCe how many UK users it has.
