Online display advertising activity in the UK has increased year-on-year despite the current economic climates, figures from Nielsen Online for the first quarter of 2009 are suggesting.

The number of display advertisers, the number of individual campaigns and the number of ad creatives used all rose by 21 per cent compared with stats for the same period last year.

Over 5,900 advertisers ran online display ad campaigns in Q1 2009 with a monthly average of 11,000 campaigns.

“Whilst other media have suffered in the amount of advertising they attract, online continues to thrive. Although advertisers are probably getting more bang for their buck through falling online advertising rates, the strong increase in the level of display advertising activity is reason enough for online publishers and media owners to be optimistic about the year ahead – particularly if the retail and finance sectors continue their heavy activity,” said Alex Burmaster, communications director, online, in the report.

In the news and information sector, OMNIsport was the most active advertiser in online display advertising.
