The reason is simple: B-to-B audiences -- especially engineering, technical and scientific audiences -- have aggregated on the Web and are increasingly finding good vertical search engines that focus on the domains they care about. Since the B-to-B audience is on the Web, this is where most of your leads will come from. In many regards it’s simple common sense: Fish where the fish are.
