One niche in affiliate marketing that I was sure would flop but has actually done really well is online therapy services. At first, I couldn't imagine people opening up to a therapist over a screen—it just seemed too impersonal. Plus, there were all these worries about data security and whether insurance would cover it. But then the pandemic hit, and suddenly, online therapy became one of the few ways people could get help. People got used to it fast, and now, many actually like it better because they can talk from their couch. Affiliates who started promoting these services early are earning solid commissions, especially since therapy often means repeat sessions. It's a reminder that niches can turn around when the world shifts. Have you seen any niches that you thought had no chance but ended up doing well?
