Where could the brand go that customers would welcome?

A familiar brand can make a new product easier to recognize. That isn’t the same as giving people a reason to choose it.

A brand can credibly grow where customers see the fit and the brand brings something worthwhile to the new category: a benefit people would value and the business can deliver. Brand extension research needs to explore both the fit and the contribution, especially when the business wants to grow beyond what it already does well.

Familiarity opens a conversation

Customers may readily imagine a trusted brand in an adjacent category. That can be useful evidence of fit. It leaves open what they would expect the brand to do differently, which existing offer it would replace, and whether the new product would matter to people beyond the current customer base.

An extension that makes immediate sense can still be undistinguished. A less obvious move can be promising if the benefit becomes clear and the brand has a credible way to deliver it. In research reported in the Journal of Marketing, Aaker and Keller found attitudes toward an extension were higher when people saw a fit and judged the original brand high in quality, or when “the extension was not regarded as too easy to make.”

Those possibilities make a simple permission score an incomplete basis for choosing where to grow. The team needs to understand what creates credibility, what might stretch it and what would make the new offer valuable in its own right.

Let the brand’s ambition and its buyers’ view meet

In our brand growth work for a food brand, the brand had a strong core business, and its next stage of growth would have to come from categories it wasn’t yet in. The executive team wanted a shared view of how far the brand could go while staying recognizably itself.

We started with the leadership team, before any fieldwork, and agreed the criteria every opportunity would be judged on. Focus groups then ran on two tracks, with loyal buyers and with a broader mainstream audience. The executive team came away with a growth roadmap, with guidelines for developing the brand in new categories, and the brand went on to launch in four new categories.

What matters for this argument is the order. Every candidate category was weighed against the criteria agreed with leadership at the start, so the roadmap brought the brand’s ambition and its buyers’ view together.

Hearing from both kinds of buyer matters in any extension. Loyal customers can help a team understand what it risks losing, and they may be unusually willing to give the brand a chance. People less familiar with it may need a clearer reason to consider the new product.

Neither perspective should simply overrule the other. An extension might be designed to deepen an existing relationship, reach new buyers or do both. The intended role affects whose response is most relevant and how to interpret a difference.

A team should also be careful about treating today’s understanding of the brand as permanently fixed. New products and communication can change that understanding over time. Research can identify the distance the business would need to travel, and it cannot promise that familiarity or credibility will develop without investment.

Fit, value and feasibility need to meet

Imagine a brand associated with convenience entering a category where people accept inconvenience because it gives them control. The familiar promise may transfer easily while offering little advantage to the most attractive buyers. Alternatively, there may be a group who wants a different balance and has been poorly served.

The possibility shows why exploring the new category matters as much as exploring the existing brand. The opportunity lies in the relationship between them.

The business also needs to consider what it can produce, distribute and sustain. Consumer enthusiasm for an imagined product cannot settle whether the company has a viable way to deliver it.

A strong growth direction brings these perspectives together: something people would value, a credible contribution from the brand and a realistic path for the business. The most useful question is where taking the brand would give customers a worthwhile new choice, more than how far the name can travel.
