The Amazon A9 algorithm begins with crawling your product page and understanding what you sell.
For example, if you sell power bank, you need to make sure A9 understand that is a power bank. Only until then it can start to show your product to buyers who are searching for "power bank".
Let's see how you can make the A9 spider understand your listing:
First, you need to describe your product clearly in Title, Bullets, Description, and Search Terms.
These are the main areas that Amazon spider will crawl and index. Make sure you include all your keywords in those sections.
However, this is NOT true…
I am really worried when I saw so many sellers adding misspelled word in their listings. This can actually HARM your listing and user experience!
Amazon has clearly stated this in their TOS: "Our algorithm accounts for stemming."
What does that mean?
Amazon can understand a buyer is looking for a water bottle, no matter whether he searched for "water bottles" or "water bottle".
An example for you :
This is one of the top-selling water bottle products on Amazon.
You cannot find this word "bottle" anywhere in his listing including backend search terms.
However, as the screenshot shows, it is indexed by Amazon for this misspelled word.
A9 is smart!
Last but not least, your content should be written in a way that is readable and make sense to buyers! Stuff keywords here and there will make buyers hard to find the key selling point of your product, which will harm your sales in the end.
Research has shown that, if you cannot let buyers find your key selling point in the 50s, they will leave…
Now A9 understands what your product is.
Tell A9 what category your product belongs to.
It can classify Your Product.
As you all know, when you create a listing, Amazon will ask you to choose a category for it.
This is a very crucial step.
You need to make sure you have classified your listing into the right category!
Why is that important?
In the first section, we showed you how smart A9 is to understand your search intent.
Now you will see A9 is much smarter than that…
It understands which keyword belongs to which category!
For example, when you search for "power bank" on Amazon, A9 knows you are looking for a cell phone accessory product. So it will show you those power bank products under the cell phone accessory category.
Let's visualize it this way:
A9 considers each product category as a shelf in a shopping mall.
It will direct buyers to the right section after it understands what they are looking for.
This means if buyers are searching for "power bank", but you put your power bank in the baby section, then your product can never be found.
amazon product category.
This is also why sometimes you find your:
Keywords are not indexed by Amazon no matter how many times you repeat it in your listing.
Keyword ranking is very low no matter how many giveaways you did.
PPCadshas very low impression no matter how high you bid for.
Buyers are browsing category page for products!
Not all buyers' shopping journey begins with a search.
Actually, there are lots of buyers start their shopping journey with browsing category pages.
Imagine you want to buy some makeup for your Christmas party, but you are not yet sure what exactly you need.
Obviously, if your product is classified wrongly, you will lose a huge amount of browsing traffic.
Now you understand how important it is to classify your products in the right category.
Let's see how you can find the most relevant category for your product.
The easiest way is to check your competitor's listing page and find the category it belongs to.
A9 algorithm can Index Your Keywords
Getting your product indexed for the targeted keywords is the first and the most important step for achieving good rankings and sales.
How to check whether your keywords are indexed by Amazon?
Step 1: Install this free Chrome extension: Amazon Keyword Index & Ranking Checker
Step 2: Paste in all your keywords, ASIN and choose your Amazon marketplace.
Step 3: Click the “Check Now” button and see the result coming out in a few seconds.
Now you can easily see what are the keywords you have been indexed by Amazon, how well they ranked and what is the search volume for each keyword.
You can also use this tool to check the index status of all your search terms after optimizing backend keywords.
We found that this product is not indexed for the keyword “glitter balloons”. So before you wasting money on ranking this keyword to page 1 of Amazon, you should first get it indexed.
Does it worth the time you will spend on getting it indexed and ranked?
Let the search volume tell you!
After checking the indexation, the tool automatically shows you the search volume for each keyword, so you can easily sort by search volume to see the most and least demanding keywords. This could save you a lot of time from running a search volume check again.
For example, I don’t think you should spend time and money on ranking “gold balloons party” with such a low keyword search volume.
