A  Bizreport.com article indicates that Google is expected to report U.S. advertising revenues of $4 billion in 2006; the entire U.S. online ad spend is expected to be $16 billion. For Google, this is a 65% jump from the numbers reported in 2005 and marks a continued pull away from Yahoo, their closest competitor.

“These growth numbers establish Google as the unrivaled king of online advertising universe, leaving Yahoo, with its greater advertising diversity and years of media experience, struggling in second place,” David Hallerman, eMarketer senior analyst (via MarketWatch) said.

All the more reason, if you want to be a player in the seosphere, you have to produce Google results.
