To establish trust and demonstrate authority on crafting, a white paper would be the most helpful option. A white paper is an in-depth report or guide that addresses a specific topic, providing valuable insights, research, or expertise. It can effectively showcase the brand's knowledge and authority in the crafting field, helping to build consumer trust.
While a landing page, viral video, and personal selling can also be effective in different contexts, they might not convey the same depth of authority and expertise as a white paper.
