Some new research published by comScore shows that display advertising appears to be more effective at influencing users' online behavior in Europe than in the US. A summary of the study has been published by ClickZ, and reports that display ads in the U.K. and Europe drove substantially more traffic to advertisers' sites and promoted a greater number of trademark search queries than in the US.

The comScore study suggests that users in Europe are 72% more likely to visit an advertiser's website, having previously been exposed to display ads, compared with a 49% lift in the US. The research also found that European users are 94% more likely to conduct a search query on an advertiser trademark after seeing an ad, compared to 40% being more likely to do so in the US.

The results seem to show a good level of impact in both markets, despite the decline in clickthrough rates from this form of advertising. comScore suggest that the differences in behaviour could be the result of lower average levels of exposure to online adverts in Europe, compared to the US, which helps drive higher response levels. Also search activity is higher in the UK, meaning that driving users to search could be easier. There is also some evidence that creativity in Europe, and in particular by UK advertisers, means that awareness and clickthrough rates can be higher.
