Internet ad revenue up 21% in 2003

Led by a spike in keyword search ads (fees advertisers pay online companies to tie a listings and/or links to their site to specific search terms), Internet ad revenue experienced a health bump in 2003 according to the Interactive Advertising Bureau (IAB). This is especially relevant during a time when other forms of advertising are flat at best. And, while keyword search ads jumped 20%, banners dropped 8%, clearly showing that context-relevant ads work.
