To diversify their affiliate portfolio and balance their income streams, affiliates can consider promoting complementary food and beverage affiliate programs alongside DoorDash. Some popular options include Uber Eats, GrubHub, and goPuff. By offering restaurant owners a range of delivery platform options, affiliates can position themselves as comprehensive resources and increase the likelihood of earning commissions from multiple programs. Diversifying affiliate partnerships can also help mitigate the impact of any changes or limitations within a single program, ensuring a more stable and resilient income stream for the affiliate.
