I’d stick with Amazon if I were you. All of my Amazon sites only have Amazon affiliate links. If you use Google Adsense display ads on your site, you’re literally taking people away from your site for the sake of just a few cents with these type of ads. If you direct them just to Amazon, then you have a greater chance of earning more money from that click.
Your Brand Persona and Target Audience. When you eventually start creating content, you have to know who you’re talking to and tailor your brand voice to appeal to them uniquely. If you aren’t targeting the right audience (those people who will lean in to hear what you’re saying), you won’t find success. And, if you can’t find a way to stand out, you’ll blend into the hordes of other brands competing for attention in your industry.
