Google took a lot of heat last month when it announced its decision to incorporate personal data into its search results. The “Don’t Be Evil” people were vilified by commentators and competitors. But its move was just another step in a shift by many marketers toward more actively tracking and responding to consumers.

Amazon gives shoppers personalized recommendations. Nike lets runners customize their trainers via Nike ID. Coca-Cola has introduced Freestyle vending machines, which enable patrons to create their own beverage by mixing together existing Coke products and then sharing their favorite creations with their friends via Facebook.

Consumers are increasingly comfortable providing their information with companies they know will use it to help personalize their products and communications, or companies providing essential services such as insurance. According to a recent study in the U.K., 75% of consumers that have an existing relationship with a company are happy to share their information with it, while 62% would share their information with a company selling products or services they need.

At Mindshare we have a name for this accelerated data-driven and consumer-focused mentality: adaptive marketing. It’s an approach that enables marketers to truly tailor their activities in rapid and unparalleled ways to meet their customers’ interests and needs based on data. It’s not just about advertising, but adapting every part of the marketing mix as well as the product itself to connect more consumers with the brand, make it more relevant to everyone and deliver more benefits.

Why is this the most exciting development in marketing in decades?

Adaptive marketing allows you to create more personalized brands, thereby eliminating commoditization. Adaptive marketing rips apart the concept of “the consumer,” a label that marketers have used to conveniently aggregate a picture of who they are trying to sell to. It assumes a classic model of mass-production, mass-appeal products promoted in mass media. The problem with this model is that it speaks to the most basic of needs, resulting in lowest common denominator marketing. This drives brands towards commodification, resulting in downward pressure on pricing… every marketer’s doomsday scenario.
