What are the most profitable niches in affiliate marketing?

Some of the top niches are: - Health & Fitness (weight loss, supplements, home workouts) - Finance (credit cards, loans, investing apps) - Tech (software, gadgets, AI tools) - Education (online courses, certifications) - Lifestyle (pets, hobbies, beauty) But profitability depends on passion + demand.
