Mail Online hit a new daily global traffic record of 12.1m daily unique browsers in October, according to ABC.
This compares with a previous record of 11.8m recorded the previous month.
According to ABC, 4.8m of Mail Online's daily traffic is UK-based with the rest coming from abroad.
ABC claims that Mail Online has 61m unique browsers per month in the UK and 132m in the rest of the world.
ABC records different devices logging on to websites, rather than different people.
The fastest growing UK newspaper website audited by ABC was the Mirror, up 124 per cent year on year to 3.6m unique browsers per day.
