Branding strategy is an integral part of product development. A brand identifies a seller's goods and differentiates them from competitors. Brands play roles for customers by conveying information, educating, and reassuring; for companies by offering legal protection and categorization; and for competitors by providing benchmarks. Strong brands have high brand equity, which adds value for firms and customers. Packaging, labeling, warranties, and service agreements are essential brand elements that build customer confidence in the brand.
