Intent to Purchase is a key metric for analyzing the success of online or offline media spending based on ROI. “It is becoming very important because we constantly have to be able to say if investing in [certain] types of media will drive towards a response,” says an agency researcher in AdAge.

One way to increase intent to purchase is to diversify your media mix---adding print or online to TV for example, according to a study by market researcher Advertiser Perceptions. Their research showed that consumers were more likely to express an intention to buy with multiple media across categories such as consumer electronics, apparel, automobiles, beer and toiletries.
