Cereal brands are models of consistency due to their repeated use of taglines and branding. A person must hear about your brand many times before they'll remember it, let alone be moved enough to buy something from you. Companies may choose to drive home a category, a use case, a tagline, or a slogan repeatedly and consistently in order to build a memorable brand. Doing customer research and listening to how people talk about your brand can help you hone the right message.
