Understanding the algorithm.

It’s one thing to decide as a brand or an e-commerce business to start selling on Amazon, but simply registering products on the platform is not enough.

With millions of sellers in the marketplace, brands need to make sure they are driving traffic to their listings in order to drive sales. Brands must be in line with Amazon’s algorithm for potential customers to find their products but more importantly, buy them.

What is Amazon’s A9 Algorithm?

Amazon’s search engine algorithm — the A9 — ensures that searchers get the most relevant results for their queries.

You know when you go onto the amazon webpage, and type in the search box whatever product it is you are looking for? This is when the A9 algorithm gets to work. The platform collects data from millions of searches and offers recommendations based on customer shopping preferences and past purchases, alongside other factors.

The algorithm includes the Amazon search results page, the different categories on the search result page, sponsored products, and search filters.


What factors influence Amazon’s A9 algorithm?

There are a number of things that influence the algorithm but we recommend working on the following first to get one step ahead of your competitors.

Keyword research

Don’t go in blind – do your research! There are several free tools available online to help you find out what keywords you should be ranking for. You want to make sure the relevant keywords are used in your ads, on your listings and in the back end of the platform to welcome the most relevant customers to your products.


Optimized listing text

Strong listing text is something that surprisingly a lot of people abandon. The text within your listing is key to ranking highly in the Amazon algorithm. Have a read of our top tips on how to optimize your listing.

Take advantage of EBC & A+

Alongside the listing copy, brands should be leveraging the power of Enhanced Content and A+ Content. This allows brands to tell their story through a mix of images and text to enhance the product listing. It allows users to modify description fields of products so that rather than just a description, brands get to paint a bigger picture.

High quality images

A good quality set of listing images matter. Amazon has strict rules surrounding uploading images including size, clarity and the amount. The main image must be of the product on its own on a plain white background, and the rest should be a mixture of product, brand and lifestyle images.

Good customer reviews

One thing many sellers don’t realise is your customer reviews count towards your ranking on the platform. We recommend that as part of your Amazon marketing strategy, encourage customers to leave reviews on your product listing.

Don’t let Amazon algorithm jargon bog you down, it’s not as complicated as you may think! By sticking to a few simple rules by the platform, you are sure to set your brand apart from competitors that may not have a strategy in place.
