Promoting a ClickBank product through Facebook Marketplace is not straightforward. Facebook has strict rules about affiliate links. You cannot directly post your ClickBank links in the Marketplace. Instead, you need to create a bridge page or a blog. This page should contain your affiliate link. Share this page in relevant Facebook groups instead. Join groups related to your product niche. Post valuable content to engage members. Encourage them to visit your page for more information. Always follow group rules to avoid being banned. This approach can help you reach potential customers effectively.
