Lead generation is the process of identifying and attracting potential customers or subscribers who have expressed interest in a product, service, or content channel. On YouTube, lead generation typically happens through strategic calls-to-action — such as directing viewers to a landing page via link in description (YouTube context) placements, offering free resources, or using end screens to capture subscribers. A well-optimized YouTube channel functions as a top-of-funnel lead generation asset — using organic reach, views, and engagement to build awareness that drives conversion rate further down the marketing strategy.
