A sales funnel in affiliate marketing should not solely seek to maximize display ads. While display ads can drive traffic and raise brand awareness, they often yield lower conversion rates compared to more targeted strategies. Effective affiliate marketing relies on building trust and delivering value through content, email marketing, and strategic partnerships. Overemphasizing display ads may lead to inflated costs without corresponding returns. Instead, the funnel should focus on nurturing leads with high-quality content, optimized landing pages, and personalized offers. Display ads can support the top of the funnel by attracting interest, but conversions typically occur through deeper engagement. Balancing ad spend with performance-driven strategies ensures a more sustainable and profitable affiliate marketing funnel.
