Google is apparently still gunning for the B-to-B market, fielding the results of a study showing that search advertising is more effective than ads in trade magazines and other business-to-business media, AdWeek writes. An online survey of 900 technology professionals involved in purchase decisions for enterprise application and security software as well as server storage found that they used search 30 percent more frequently than trade periodicals in the research phase, 21 percent more frequently in the consideration phase and 62 percent more in the final purchase phase. More than half said they used search engines to research purchases: 40 percent during consideration and 20 percent during the final purchase phase. Millward Brown conducted the study.
