I would probably rely mostly on Amazon as an affiliate – talk about products you use while using an affiliate link. You don’t necessarily have to focus your entire content on reviewing products, just mention them in your articles and your experience with them – how they helped you. Amazon is good for obvious reasons – super high conversions and most products already have lots of reviews which is very valuable as an affiliate.
Once you have the affiliate links you need, it is time to present them to your audience. As you start using affiliate marketing to talk about products, you need to be aware of how your audience perceives you. If your website appears to be only after their money through an overwhelming amount of affiliate links, then they are more likely to simply leave your site.
