The video shows two ways to add an Amazon affiliate link to a Facebook page, allowing users to monetize their Facebook audience in a specific niche. The first way is to promote a single item on the Facebook feed by adding a photo and a caption with the affiliate link. The second way is to use Linktree, a free landing page builder, to create a landing page with multiple affiliate links. The landing page can be shortened using bit.ly and added to the Facebook page through the 'Enter Website' tab.
