EMarketer is predicting U.S. search marketing spending to top $13.6 billion this year, slightly lower than SEMPO's prediction of $15.7 billion. And search marketers seem to be comfortable maintaining or increasing their spend, even as average CPCs trend upward. "About three-quarters of respondents worldwide said they could live with further rises in paid placement prices," the analysts wrote. "Among those who said they could stand more price increases, more than half wanted those increases to be 30% or less."
