While Amazon holds very secretly the details of its A9 Search Algorithm, there are a few key factors that we know can definitely help to determine a product’s rank.
In fact, when you create an Amazon product listing, you are actually telling Amazon how your product looks like.
Then, when customers click on your product listing and make a purchase, they, too, are telling Amazon that this product is in fact, exactly as described and precisely what they were looking for.
In fact, you should think of Amazon’s A9 search engine as the smartest human being you’ve ever encountered. However, this person lacks confidence in their answers, and it’s not until thousands of people tell this person they’re right, that they start to believe it themselves and acting accordingly.
And that’s basically how Amazon SEO and the A9 algorithm work together.
