SEM spending in North America topped $12 billion in 2007, up from about
$9.4 billion the prior year. The survey is forecasting spending to top $25 billion in just three years--up significantly from last year's predictions for 2011.
Not surprisingly, paid search took the lion's share of spend, with roughly 87%, while organic search came in at about 11%. Lastly, marketers spent a small percentage (1.4%) of their search marketing budgets on technology investments, and an even smaller percentage (0.07%) on paid inclusion.
