Affiliate marketing is the art of marketing products, services or information for others. It doesn't require that you ever house or warehouse a single thing. But it does require that you have an audience to market those things to online. Without that audience, whether it's through search engines like Google or social media channels like Facebook, you'll find a difficult time with affiliate marketing.
Facebook has been a method for lead generation since its inception. Originally, companies could use outbound links in their posts and information in their bios to attract strangers to their websites. However, when Facebook Ads was launched in 2007, and its algorithm began to favor accounts that used paid advertising, there was a major shift in how businesses used the platform to capture leads. Facebook created Lead Ads for this purpose. Facebook also has a feature that lets you put a simple call-to-action button at the top of your Facebook Page, helping you send Facebook followers directly to your website.
