Design a strategy that uses social proof, such as customer testimonials, reviews, and case studies, to attract new leads. Identify where these assets can be placed across digital channels, such as [website landing pages], [social media platforms], and [email marketing]. Discuss how to leverage user-generated content and third-party reviews to build trust and drive lead generation. Provide specific examples of calls to action (CTAs) that effectively utilize social proof to convert visitors into leads.
