“In many ways, online marketing and online media has done itself a disservice by focusing on targeting more than reach. A couple of very interesting studies are out there. One was a study by Nielsen, about the relative contributions of reach versus targeting in effectiveness, and they concluded, with a survey of about 500 econometric models, that targeting only adds about 10% to the effectiveness of the campaign on average. A very similar result came from some work by D2D, where they looked at over 200 econometric models, from a wide range of categories, and they concluded that targeting of a campaign adds only about 10% to effectiveness. So the same numbers, two very different methods.”
