What a brand actually is
A brand is not a logo or a colour palette. It is the sum of associations that exist in the minds of people who encounter your business — what they think of when they think of you, how that makes them feel, and whether that disposes them to buy from you, recommend you or pay a premium. You can shape these associations through deliberate communication, product quality and customer experience, but you cannot fully control them.
The positioning question
Brand positioning is the distinctive space your brand occupies in the minds of your target customers: what makes you different from alternatives and why that difference matters to them. Effective positioning is both distinctive (memorable, different from competitors) and relevant (meaningful to your target customers' needs and values). Generic positioning — we are a high-quality, customer-focused provider of X — occupies no distinctive space and is easily forgotten.
Building mental availability
Byron Sharp's "How Brands Grow" research framework argues that the primary mechanism by which brand drives sales is mental availability: the probability that a brand comes to mind when a customer is in a buying situation. Mental availability is built through reach (being seen by many people in your target audience), distinctiveness (being recognisable) and consistency (consistent use of distinctive brand assets over time). Changing your brand identity frequently undermines mental availability.
Practical steps
Start with a clearly defined target audience (specific enough to be useful, not so narrow that it limits growth). Define your positioning in a single sentence your team can actually use. Create a simple but distinctive visual identity. Apply it consistently across all touchpoints — website, social, packaging, email, in-store. Then be patient: brand building is a long-term activity measured in years, not campaigns.
