Translation: Amazon won’t let you join their affiliate program if your site is involved in anything illegal, deceptive, violent, or hateful. But even if this doesn’t describe your site (and I hope it doesn’t!), keep in mind that sites of an “adult” nature may not be allowed either. Also, even if your site is totally family friendly, if it’s focused on kids it may not be allowed, as Amazon says it won’t accept sites directed toward kids who aren’t teenagers yet.
It works for me & I've used it myself. It's really hard to promote something you haven't personally used and loved. A good example of this for me would be FlexJobs. I get a lot of questions about this program. If someone asks me where to find something in the dashboard, I can tell them. If they tell me they aren't finding ANY jobs to apply to, I can provide them with a list of steps that may change that. If they ask me if I pay for a membership myself, I can, with 100% honesty, say YES.
As with your niche, your approach to implementing links will depend on your site’s purpose. Feel free to experiment with different strategies, but always remember that your focus should be on providing value to your audience. If you fail in that task, visitors won’t trust you, click on your links, or return in the future. Make sure you write quality content, therefore, and keep an eye on your conversions to see what’s working (and what’s not).
Affiliates are most successful when the products they promote match the interests of their followers and subscribers. In addition, many successful affiliate marketers advise recommending and promoting only products that the affiliate is personally familiar with. That’s because familiarity with the product, program, or service helps build trust between the affiliate and end-user.
