The most advanced guide to Amazon's A9 algorithm ever written

What follows is the most advanced guide to Amazon’s A9 algorithm ever written. We’re not just skimming the surface here. We’re diving deep into the belly of the beast, and dissecting exactly how you can use it to your advantage.

 Or to put it more plainly – how you can use it to make more money. 

 You will find no personal opinions here. Everything is translated into plain English directly from the Amazon science literature, alongside presentations from members of the A9 team themselves.

As we said, right from the horse’s mouth.

 Let’s get into it…


Mastering the Amazon A9 Algorithm

By the end of this article, you’ll know more about the Amazon A9 algorithm than 99% of Amazon sellers.

Let me explain.

The Amazon algorithm is a confusing beast. Talk of honeymoon periods, the “A10 algorithm,” hunger scores and a head-spinning array of other things you’re meant to know about… 

So who do you turn to when you need the REAL answers? 

Well, we went right to the horse’s mouth: The people who wrote it. 

We’ve trawled through Amazon’s own scientific literature (so you don’t have to) – and figured out exactly what’s fact, and what’s fiction.

Spoiler alert: There’s no such thing as the Amazon A10. But we’ll get to that later.

Now, before we dive into the deep end, let’s recap exactly what the A9 is.

In the simplest terms, it’s the algorithm that decides which products show up when you type something into the Amazon search bar. 

Of course, as we all know, there’s a bit more to it than that.

While the core purpose of the machine has never changed, its inner workings are constantly learning and evolving. 

So we’re going to break down the A9 into its key components. 

We’ll explain what each component does, how it impacts your products’ visibility on Amazon, and above all, how you can optimize your business to work in harmony with the A9.

And as you read through, you don’t have to take my word for anything – you can test this all yourself. 

Yes, this guide will give you plenty of insights you can implement straight away. But it will also provide you with a platform to carry out your own tests. To spark your own insights, and make your own breakthroughs – no technical knowledge required.
