The latest results from ABC show a 31.69 per cent rise in unique browsers for Standard.co.uk, taking to to a monthly figure of 3.8 million from 2.9 in June, when the site recorded a fall of 12.57 per cent.
Standard.co.uk had seen a rise of 33 per cent for the Standard in May, which followed a previous dip.
The latest results also show that the Independent's website recorded an "all-time high" of 16 million unique browsers in July, as stated by the title in a release.
This reflected a 25 per cent rise in unique browsers from June to July for the Independent's website, the second highest month-on-month rise in ABC's results today.
The Independent's daily traffic results were also up, by 21.42 per cent, again the second highest.
In a release the Evening Standard said the rise in unique browsers was helped by the "pre-Olympic buzz" in July, ahead of the Games in London.
According to the release "Standard.co.uk went on to record an increase of 20 per cent to 40 per cent on most days throughout the Olympics in August as it broke stories and published exclusive photos alongside its print partner."
It added that for the Independent.co.uk, "July has been the highest performing month ever" for all its "certified metrics; global and UK unique browsers, page impressions and daily unique browsers".
In a statement managing director for digital Zach Leonard said "July was an outstanding month" for both sites.
The Telegraph's website saw the third highest increases month-on-month, for daily and monthly unique browsers, of 10.52 per cent and 13.59 per cent respectively.
All other news sites saw increases in total monthly traffic for July, including a 7.4 per cent rise for Mirror Group Digital, a 4.49 per cent rise for the Mail Online, a 3.23 per cent for the Metro website and a 1.02 per cent increase for the Sun website.
Only the Metro and The Sun websites experienced a slight drop in average daily traffic of 1.11 per cent and 0.21 per cent respectively.
