Brands spend millions trying to win attention and trust. One of the most effective shortcuts may be surprisingly simple: love. In marketing, words and symbols associated with love can make people more receptive, more generous, and more likely to act.

Some brands have known this for years. Southwest leans into it with its “LUV” ticker and heart-forward branding. Subaru has built campaigns around love as part of its identity. That is not accidental — it reflects a deeper psychological response.

Research shows that simply prompting people to think about love can increase helpful behavior. For example, charitable appeals using the language of love drive significantly more giving than neutral messaging. Even visual cues matter as heart-shaped design elements have been linked to higher tipping and warmer responses. Diners whose bills arrived under a heart-shaped plate left tips that were 17% higher than those whose checks came under a round plate, and 15% higher than those whose checks came under a square plate.

Why does this work? Part of the answer may be the love symbolism often triggers release of oxytocin — a chemical often linked to trust, empathy, and connection. When branding delivers those feelings, it can strengthen how people relate to a product, a message, or a cause.

The takeaway for marketers is clear: love is not just a sentiment — it is a signal. Used thoughtfully, it can make brands feel more human, more trustworthy, and more persuasive.
