Two weeks ago, I wrote about the fact that look-alike modeling of audiences in digital advertising has gotten out of control. The models are applied so loosely, by so many today, that everybody ends up being in every look-alike model.
Companies create look-alike models to extend the potential target audience from a small kernel of known customers or audiences into much bigger pools to help marketers get more scale.
Theoretically, the models should be built in such a way that the new, look-alike audiences are as desirable and performant as the audiences they were built from. Or, at the least, significantly more desirable than general audiences overall.
However, as everyone in the digital ad business knows, look-alikes today are hooey. In a desire to create audiences that are large -- that have high “match rates” and can be acquired cheaply -- suppliers and buyers most often now build look-alikes that look almost nothing alike.
The problem, as media and marketing research legend Bill Harvey told me while discussing the problem over lunch recently, is that what we really want and need are “act-alike” audiences not look-alikes.
There is a reason that Bill was the wizard behind the invention of the ADI (Area of Dominant Influence) and the notion of media-defined regional marketing areas, which was later copied in the creation of the DMA (Designated Marketing Area). Bill is brilliant and can see directly to the root of a problem, and its solution.
Our industry needs to stop talking about look-alikes, which mean nothing but sound great, and focus on delivering act-alike audiences when we are trying to expand a target audience sample into larger audience delivery that is not only efficient, but is actually effective for the marketer.
Finding new prospective customers that “act like'' existing customers is what marketers really want when they are defining target audiences for advertising campaigns. That is what we should be finding for them, and that is what we should be held accountable for.
Do you agree? Isn’t it time to get rid of look-alikes and time to focus on act-alikes?
