Brands with smaller market share have fewer buyers AND those buyers are slightly less loyal — they are penalized twice. Loyalty differences between brands are minor and are mostly a mathematical consequence of market share, not of brand strategy or emotional attachment.
Brands grow primarily by acquiring more buyers (increasing market penetration), not by increasing the loyalty or purchase frequency of existing customers. Loyalty metrics rise as a side effect of growth, so targeting loyalty as the primary growth lever is misdirected effort.
Brands grow by being easy to think of (mental availability) and easy to buy (physical availability) across the most buying situations. Marketing's job is to build memory structures that trigger the brand in relevant moments and to maximize distribution and presence, rather than to differentiate or persuade.
Most of a brand's customers buy it rarely and also buy competing brands — they are 'polygamous' across a repertoire rather than monogamously loyal. Because light buyers are numerous, they collectively drive a large share of sales, so brands cannot survive on heavy loyalists alone.
Since brands within a category largely share the same broad customer base, narrow targeting and heavy segmentation waste reach. Mass marketing that reaches all category buyers — including non-customers and light buyers — is more effective for growth than focusing on a defined niche.
Brands compete by being recognizable and salient through distinctive assets — colors, logos, characters, taglines — rather than by being meaningfully different in product attributes. Buyers cannot articulate real perceived differences between brands, so building and protecting recognizable brand assets matters more than claiming a unique selling proposition.
