NME.com, Nuts.co.uk, Nowmagazine.co.uk and Whatsontv.co.uk are among the websites in IPC's stable that are set to take advantage of the new arrangement.
The partnership will also see IPC Media become a partner of Premium Publishers Online, the sales network that acts as a buying point for agencies and advertisers looking to book pan-European campaigns.
IPC's move comes as IAB Europe today forecast that online ad spend for 2007 will reach Euro 11.5 billion (£ 8.3billion) across the continent - a rise from Euro 8bn (£5.7billion) in 2006.
IAB Europe assigned much of the increase to growth rates of 30% to 40% in markets including the UK, France and Germany.
The trade body also said that Europe was likely to lessen the gap in online ad spend compared to the US from Euro 4.8billion (£3.4billion) last year to Euro 2.1billion (£1.5billion in 2007.
