IAB Europe’s annual AdEx Benchmark survey is the definitive guide to the state of the European online advertising market. Released today at IAB Europe’s Interact conference in Barcelona, it shows that 1 in 5 advertising Euros in Europe is now spent online.

Individual market growth ranged from 55.5% in Russia and 46% in Serbia, to 5.5% in Norway and 4.6% in Romania. Central and Eastern Europe (CEE) markets have increased their share of the total from 10.1% in 2010 to 11.8% last year. Russia is now the sixth biggest market with a value of €1.12bn, buoyed particularly by a surging search market. Together the top five markets (UK, Germany, France, Italy, Netherlands) account for almost 67.9% of the total online advertising market, down slightly from 69.2% in 2011.

Head of Advertising Research at IHS Screen Digest and author of the research, Daniel Knapp explains, “Advertising markets are in general very susceptible to changes in the macroeconomic environment – in other words, in an economy where we have the European sovereign debt crisis, high unemployment and cutbacks in consumer spending, we would expect advertising spend to suffer disproportionately as it did on most media in 2011. However, online enjoys a number of unique attributes that have protected it from this effect.

Firstly, it’s a question of formats – advertisers increasingly recognise online as a branding medium; video commands a significant and growing share of spend, and search continues to deliver sound and measurable results. Secondly, the explosion of ‘big data’ has delivered enhanced targeting capabilities improving monetisation of publishers’ inventory. Thirdly, there is a long term trend for advertisers to shift ad budgets from mature to emerging markets, which is fuelling their online economy. An expanding broadband infrastructure adds to the attractiveness of those markets."

A question of formats
The ROI-centric search format enjoyed the highest growth rate of 17.9% in 2011. However newer formats including video and mobile helped lift the value of Display ad spend, coming a close second at 15.3%.

Video now accounts for 8.2% of online display
Video’s ability to convey brand messages in a narrative makes it attractive to the big spend advertisers who have a strong legacy in telling stories through TV, the classic branding medium since the age of ‘Mad Men’. AdEx Benchmark 2011 includes online video advertising figures for 14 markets, where video represents 8.2% of the total online display market value. It ranges from its highest at 9.8% in Sweden but is also gaining traction in CEE markets as 5.8% in Poland indicates. In Germany and the UK video has already crossed the €100m threshold. In the UK the market is worth €126m; in Germany €117m.

Mobile average growth rates of 45%
While mobile advertising is still a nascent format with mobile display spend contributing 1-3% of online Display ad spend, it is growing rapidly. The nine markets that reported mobile Display advertising for both 2010 and 2011 recorded an average growth rate of 45.6%.

Search experienced strongest growth rates in CEE
Paid-search continued to grow double-digit at 17.9% in 2011 and as such it remains the biggest format in online advertising. Search accounts for 46.5% of total online advertising spend compared with 33.6% for Display and 19.2% for Classifieds and Directories. In 2011 it was the CEE region that really drove the growth of Search, with Croatia, Hungary, Poland, Russia and Slovenia all experiencing significant increases in spend. What the figures alone conceal is the innovation in search – from video to location-based services, data-driven planning to cross-media campaigns with TV in particular, it is thanks to the continued creativity of the online advertising industry that allows for search to shine.

The rise of Big Data
With a 15.3% growth, Display advertising continued its 2010 renaissance, driven both by the recognition of online display as branding medium and the explosion of the big data economy. Big data relies on the rich metrics received through the online medium to plan display advertising. Using ad exchanges, real-time bidding and algorithmic trading, advertisers can reach both broad and niche audiences that meet their exacting criteria. These data-driven techniques increase the cost-efficiency of online advertising, maximising cheaper, remnant inventory to reach consumers. Search advertising has led the way in this data-driven approach and has enjoyed explosive growth across Europe.

Alain Heureux, President and CEO of IAB Europe, concludes “.Innovation and diversity have driven the outstanding growth of the European online advertising sector, which now accounts for over 20% of total advertising spend. With one in every five advertising Euros in Europe being invested in the online medium, it’s clearly a vital part of the region’s economy. In Barcelona this week we have over 500 decision makers from the digital sector celebrating this milestone and looking to build the industry for the future.”
