57% of People say Search Engines are More Important than Ever
and 67% of the online search population is driven to search by offline channels.
In June 2007, iProspect partnered with JupiterResearch to conduct a study of online users about the influence of search titled "iProspect Offline Channel Influence on Online Search Behavior Study".
More interesting is that offline events that generated the thought to learn more, are driving people to search engines instead of following the ad's call to action. As an example 30% of people that responded to a magazine ad did a search instead of using the ads URL. That means that your landing pages need to be indexed and/or linked to from the the resulting search page in order to continue the initial ads conversation.
