he research was compiled for the EIAA's Marketer's Internet Ad Barometer survey, based on answers from over 500 senior marketing executives with responsibility for advertising budgets across Europe.

It showed that marketers expect to spend 7.6% more on online marketing next year, rising to 15% more in 2011. The increase in spend is driven by the effectiveness and ability to target, participants said.

Alison Fennah, executive director of the EIAA, said: "The Marketers' Internet Ad Barometer findings reveal that online advertising is continuing to thrive and grow due to its flexibility, accountability and ability to offer brands a robust return on investment while the recession impacts overall marketing budgets.

"For this reason, online advertising is further consolidating its position as the medium of choice for marketers across Europe."
