The retail industry continues to be the biggest online ad spender in the US, according to the latest revenue report from the IAB and PwC. Retail advertisers accounted for 20% of the $17 billion in first half (H1) revenues, or $3.4 billion. Interestingly, though, that’s actually a decline from H1 2011, when the retail industry accounted for 24% of ad dollars, or $3.5 billion. So, while overall online ad revenues rose 14% year-over-year in H1, retail ad spending was stagnant.
Behind the retail industry, auto advertisers accounted for 13% share of online ad revenues (up from 11% last year), as did financial services advertisers (unchanged from H1 2011). In the 4th spot, telecom accounted for 12% of online ad revenues, down from 14% last year, while the 5th-largest verticals, computing products and leisure travel, accounted for 8% of revenues.
