Definition

Authenticity refers to the quality of being genuine, transparent, and true to a brand’s identity, values, and purpose. In marketing and advocacy, authenticity is demonstrated when a brand communicates honestly, delivers on its promises, and encourages real voices—such as customers or employees—to represent it.

Authentic content fosters trust, emotional connection, and long-term loyalty. It is especially critical in influencer marketing, where audiences value sincerity and are quick to detect insincerity or overly promotional messaging. Brands that consistently act with authenticity are more likely to inspire advocacy and word-of-mouth support.
