According to the "European Online Advertising Forecast, 2006 to 2011," released by JupiterResearch, search engine marketing expenditures in Europe are rising, and for the best of all possible reasons - Europeans are buying more online.

Internet Retailer estimates that as the Internet becomes mainstream in Europe over the next several years, by 2011 European marketers will spend Eur83 billion on online advertising, representing 8.3% of all European advertising spending.

Search engine marketing (SEM) will account for the largest part of that growth, increasing from 41% of total online ad spending in 2005 to a projected 49% in 2011.

In fact, already last year, in order to reach the increasing number of European online shoppers, 65% of the search marketers Jupiter surveyed said they had upped their paid search spending.

In addition, new advertisers are coming online — following the consumers. As Jupiter analysts wrote, "Internet penetration grew from 46% in 2004 to 49% in 2005, and will reach 58% in 2011."
