Measuring Marketing ROI Along the New Path-to-Purchase

The internet has reshaped the consumer’s path-to-purchase more than anything since Bulova aired the first television advertisement in 1941. Although online advertising has been around since Prodigy was promoting Sears’ products in the 1980s, measurement efforts have failed to keep up with the evolution of digital marketing and its impact on buyer behavior. The 21st-century consumer is more instrumented, interconnected, and informed than ever, and the “funnel” concept from 1898, used to describe the consumer decision journey, has been replaced by loops, mazes, and clouds!

New media have given consumers new opportunities to evaluate brands and to advocate on their behalf. In fact, the entire consumer decision-making process can be completed online from the time a need is triggered through the purchase and post-purchases stages when a buyer voices her (dis)satisfaction online. While the idea that this journey is no longer linear has been around for years, most efforts at incorporating digital marketing into marketing mix models fail to recognize this fact. Most of today’s applications of marketing response models are based on marketing science from the 1960s and 1970s.

Marketing science in the academic arena has evolved tremendously since the first application of marketing mix models in the late 1980s. There are more recently developed econometric and statistical techniques which must be utilized to properly measure the interdependencies among paid, owned, earned, and shared media and their impact on buyer behavior. In today’s multiscreen world, a television ad may send a consumer online to conduct a search for more information or directly to the company’s website. She could perhaps make the purchase online and then tell her friends about her purchase through her content-sharing service of choice. She might print a digital coupon at home to take to the store later or even receive a coupon on her smartphone while she’s in the store. When she returns from the store, she could search for a recipe to use the ingredients she just purchased on sale with the digital coupon she found online. She then hops back online to tell her friends about the dish she just prepared. All this activity was triggered by that initial television ad.

In order to give credit where credit is due, one must consider the direct, indirect, and feedback effects mentioned above. That simply can’t be accomplished in models that view the consumer decision journey as a linear process. It requires far more than simply adding digital measures alongside offline marketing activities into a single-equation model. With this revised role of marketing, traditional models are struggling to properly measure the impact of digital marketing. It’s time to “hit reboot” and to begin leveraging 21st-century analytics to measure marketing’s ROI along this new path-to-purchase.
