Mountain View, Calif.ÔÇöGoogle characterized business as "very, very good" when it announced in a conference call Wednesday that its fourth-quarter net earnings nearly tripled to $1.03 billion and revenue grew 67% to $3.21 billion.
Aggregate paid clicks, which include clicks related to ads served on both Google sites and its AdSense partners, increased about 61% compared with the same period in 2005.
"Business continues to be very, very good here at Google," CEO Eric Schmidt said during the conference call.
Google co-founder Sergey Brin said one particular strategy the company adopted last quarter has helped improve search monetization.
"[With] our ad systems, we focus not just on making money but also on the ad quality,ÔÇŁ he said. ÔÇťIn the fourth quarter, we continued to enhance our ad matching by eliminating ads from some of our less commercial queries while showing more ads on commercially oriented searches. And as a result, the percentage of queries that receive ads have gone down by several points, but monetization has improved."
