A brand is a name, symbol, design, or combination that identifies and differentiates products or services. It provides product identification and serves to differentiate competing products or services. The legal term for a brand is a trademark. A brand strategy should answer key questions about target customers, the brand's value proposition, why customers should believe in the brand, and how to communicate and implement the branding plan. Effective brand strategy involves strategic analysis, defining the brand identity and value proposition, building relationships with customers, and implementing an identity system to position and track the brand.
