Though search traffic on Yahoo is substantially
lower, Greg Meyers suggests supplementing your more pricey Google campaigns with Yahoo Search Marketing ads to get more bang for your buck. You can often snag head-of-the-tail terms or even
competitive longer-tail terms at a much lower CPC with Yahoo.
"With Analytics continuing to make an impact in search, more and more advertisers will realize that they simply cannot afford Google anymore," Meyers says. "In fact, when advertisers start realizing their profit margins are not what they were before and applying them to ROAS and ROI metrics, they will start to realize the value in putting more money into Yahoo."
