How do affiliate marketers deal with competition?

Competition is always there. To deal with it, you should find sub-niches. Instead of "fitness," focus on "home workouts for seniors." Instead of "tech," focus on "budget laptops for students." Narrowing down helps reduce competition.

I deal with competition by adding personal branding. People may find hundreds of affiliate sites, but only mine has my story, my experiences, and my reviews. That makes it unique and trustworthy.
