For this research study, Google and Dove worked together to explore the impact of online advertising on in-store sales. The study found that the inclusion of online advertising resulted in a 6% overall sales uplift. Online advertising was most effective when used in synergy with national TV, a combination that led to a 11% sales uplift. Most interestingly, it was found that although the campaign advertised a single product, it was effective in generating sales over the whole range.
