User-generated content (UGC) refers to any form of content—such as text, images, videos, reviews, or social media posts—created and shared by individuals rather than brands. Often produced by customers, fans, or online community members, UGC is typically unpaid and can include blog comments, forum posts, and social media interactions. Businesses leverage UGC to build trust, enhance brand authenticity, and boost engagement, as it serves as a form of social proof. Integrating UGC into marketing strategies can improve search engine rankings, drive organic traffic, and increase customer loyalty.
