AOL, which puts its subscriber growth down to its flat-rate monthly subscription service, said users in the UK and France spend more than an hour a day online.
German customers spend more than half-an-hour a day hooked up to the internet.
"MediaMetrix measurements indicate that European subscribers average up to 330% more time in proprietary areas of the AOL service than is the case for competitors," AOL said in a statement.
Michael Lynton, president of AOL International, said, "Not only are we experiencing record subscription growth in Europe, but we also are continuing to lead all comers in time online -- the most closely watched barometer for advertising/commerce partners. That's why AOL Europe is also experiencing a growing roster of deals with leading partners around the world."
AOL Europe recently signed partnership deals with companies such as Amazon.com, Procter & Gamble and Kingfisher.
