I focus on building authority because I believe that for anyone to buy anything from you, whether online or offline, they must first trust you.
How do you earn people's trust?
That's right, you earn it with the content you have.
You have to demonstrate to them that you know what you're talking about.
This is why it's good to build authority blogs that also feature affiliate links.
The idea of a "micro-niche site" pushes many to fail.
That's because they think they only need to specialize in a certain product, fill it with reviews, and they're on their way to making bank.
If it only were that easy.
The truth is your domain authority will only rise to the point where your commercial intent pages will get traffic if you have enough informative content.
So focus on looking for questions people ask about the problem solved by the affiliate products you are selling.
Start there, fill your websites with answers to these questions, and make them authoritative and credible.
Deliver the results people are looking for when they type in these questions.
Once you do that, you can start building commercial pages like reviews or top ten lists.
