As you can see from the screenshots of some of my commissions above (which are 100% real, btw) I’m not going to create some fake “$150,000/month income report” and tell you that I made that much working 1 hour a day.
Your neighbor could be making a killing promoting hunting rifles, but what do you, a 19-year-old college student, know about guns? Don't mimic what other people are doing just because it seems to be working for them.

In fact, some people with huge followings can hardly sell anything with affiliate marketing because their audience doesn’t trust them or isn’t connected. Often with a smaller audience you are more connected with your followers and they are more connected to you which means they are also willing to support you by trusting your opinion on products and using your affiliate links.
Personally I only ever recommend products I love or have used myself and think will add value to my audience. My motto is “if I wouldn’t recommend it to my mom, I won’t recommend it to you.” This lets an audience know that they aren’t stumbling through products by chance but instead are able to trust your recommendation.
