The warmer your visitors are, the more likely they are to convert on the offer you're promoting. Sometimes, they need more time and more attention. That's the purpose of a Multi-Step Pre-Selling funnel. You're not just sending people to your optin page. Once they join your list, they are redirected to a 2nd page, delivering more content, educating them on the offer and thus pre-selling it for you! This is a highly effective weapon that can 3x your sales.

The two forms of marketing are differentiated, however, in how they drive sales, where affiliate marketing relies purely on financial motivations, while referral marketing relies more on trust and personal relationships.
