Nielsen recently analyzed an online CPG campaign geared towards women 25-54 that ran across three ad networks and a women’s interest site. The study showed the campaign successfully reached its intended audience only 27 percent of the time and instead was most often viewed by older demographics outside of the desired group.

Even more surprising was the degree of variability between the different media sellers. Nielsen found that while the three ad networks reached the campaign’s intended audience 20-30 percent of the time, the women’s interest site, due to its audience composition, was most successful at delivering the intended audience.
