It seems obvious, a brand’s currently heaviest buyers generate more sales and profits (per customer) so they should be the primary target for marketing.
This is commonly held misconception. The rise of direct marketing and CRM gave this fallacy a big plug, after all it can be hard to justify sending expensive letters to light customers.
But if our aim is to grow sales then our efforts should be directed at those most likely to increase their buying as a result of our attention. It takes only a moment of thought to realise that customers who already buy our brand frequently are going to be difficult to nudge even higher.
If, instead, our aim is to prevent sales losses then heavier customers would seem more promising – after all they represent a lot of sales we might lose. But then again, they are more loyal, other brands make up less of their repertoire, their habit to buy our brand is more ingrained, our brand has rather good mental and physical availability for them. In short, they aren’t particularly at great risk of defecting nor of downgrading.
So the idea that heavy buyers of your brand (“golden households” or “super consumers”) are your best target is flawed. Dangerously simplistic.
