How to Do Amazon Keyword Research: A Step-by-Step Guide

Just like any other search engine, Amazon’s own search engine is also being updated regularly. You’ll need to optimize your product info regularly to keep your product ranking on Amazon, and that optimization process greatly depends on keywords.

How to Do Amazon Keyword Research

Today we are talking about how you can research and optimize your keywords for Amazon. I’ll provide a step-by-step guide on how to do Amazon keyword research and keep your ranks high.

What Are Amazon Keywords

How to Do Amazon Keyword Research

Google or Bing isn’t the only place people do online searches. Many websites also provide a search option so you can find what you need.

Amazon, one of the most widely used e-commerce platforms across the globe, also provides a search option to find products quickly. Amazon has its own search algorithm. This powerful algorithm helps shoppers to find relevant products through a range of keywords.

These keywords (words and phrases) are indexed by Amazon and have been a way to optimize product pages. The higher you rank on Amazon’s search results, the more your sales grow.

Let’s Meet the Amazon A9

How to Do Amazon Keyword Research

Amazon uses a powerful algorithm named “A9” to list the best search results for any given query. This algorithm evaluates keywords to find out the best relevant product for your search query. A9 is one of the most powerful algorithms for products in the world.

Unlike Google’s algorithm, A9 also takes account conversions and product reviews into account to rank a product.

What this means is, that if a product can be considered a better-selling product in terms of volume and conversion rate, or has many positive reviews; that product is more likely to rank higher than a product with low sales volume, and conversion rate, or negative review.

How Amazon Keywords Work

Keywords are important to rank your products. How well you place the keyword will determine how high you rank up on the A9 search results. Not all keywords will get the same importance. Here is the priority order of how A9 prioritizes the importance of your keyword:

Product Title> ‘About this Item’ (Bullet Points)> Hidden Keywords> Product Description

Let’s have a deeper look.

Within the title

How to Do Amazon Keyword Research

The title gets the most importance from A9. This is the reason you see almost every product title on Amazon is a mile long and stuffed with a bunch of keywords. People try to put as many relevant keywords in the title as possible.

The general guideline is to use the main keywords at the start of your product title and include all the main variants of your particular keyword that people are searching for. This practice is called “Front-loading.”

On the product page

How to Do Amazon Keyword Research

The next big and important placement is the product page. Shoppers will click through your title, and leave your page without any conversions if they don’t find the correct and reliable information.

Your product page should contain product detail that matches your product description. Avoid
reusing keywords you’ve already put in your title. You also should provide bulleted lists of the benefits of your product and try to answer prospect questions with informative keywords.

Hidden keywords

How to Do Amazon Keyword Research

A9 also has the ability to hide keywords from customers. These keywords are used to rank your products but stay hidden from the shoppers. Usually, related keywords with a high search volume that don’t describe your product (audience-focused or competitor keywords) go here.

These keywords are named “hidden/backend” keywords and you’ll get 250 bytes to put them in your seller account. You can also put commonly misspelled words related to your products.
You’ll need to properly utilize the allocated space and update the keywords regularly.

How to Do Amazon Keyword Research: Step-By-Step

Now that you are familiar with the basic concepts, let’s dive deep into how to use The Amazon keyword research process to rank your products.

Step #1: Use the Amazon search bar

How to Do Amazon Keyword Research

This is a pretty straightforward and time-consuming way to find related keywords. Just enter your product’s name in Amazon’s search bar, followed by the letter of the alphabet; one letter at a time.

This way, you’ll be able to find out related keywords that the customer sees when they type in your product’s name. This will give you a good start, and it’s free.

Step #2: Find relevant products

How to Do Amazon Keyword Research

Amazon has an amazing feature named “frequently bought together/buy it with” where it showcases relevant products that’ll compliment your product.

This is a great way to come under the spotlight and reach the customers who didn’t even know they needed your product. Collect keywords from there and include them as hidden keywords.

Step #3: Check your Google ranking

How to Do Amazon Keyword Research

Customers who are buying for the first time often search multiple sources before making the purchase. And most people still use Google as their primary search engine. That’s why ranking on Google will also help you increase your conversion and create a loyal client base.

When people search for a product online, most of them intend to buy it. Utilizing your Google ranking and optimizing your Amazon listing will help you to be there when the customer is ready and looking for you.

Step #4: List your seed keywords

How to Do Amazon Keyword Research

Seed keywords are the primary keywords that you use to get ahead of your competition. Just like any other marketing strategy, competitor research is a must in Amazon keyword research as well.

You can either do it manually or take help from a keyword research tool. The key is to note down 4-6 seed keywords that you’d expect your clients to search on Amazon. The seed words should be about 2-3 words long and relevant to your product.

Step #5: Use a tool

Nowadays, there are lots of tools available to make your keyword research smooth, hassle-free, and efficient. That is why I am explaining this separately. You can use tools like Amazon’s Reverse ASIN search tool, Google keyword planner, Ahrefs, Sonar, Helium 10, and many more.

These tools will help you to find hundreds of long-tail keywords within a few clicks. Your job will be to filter those keywords to find the most suitable keywords for your product. They will also help you to analyze your competitor’s keywords.

Step #6: Insert your keywords into the Amazon listing

How to Do Amazon Keyword Research

Now, the race begins. You‘ll need to insert the seed keywords into your seller account to start ranking for them. As I’ve mentioned earlier, keyword placement is essential. You shouldn’t use one keyword in more than one place.

Find the best place to put your keywords and try to provide as much information as possible. Some keywords will go in the title, some will take place on the product description page, and some will remain hidden from the customer.

Do not stuff your product page with just keywords. If the buyers don’t find the right information, they won’t buy from you. Use keywords to carefully enhance your product description.

Step #7: Keep researching

How to Do Amazon Keyword Research

Marketing isn’t something that you do once and gets over with. It is a lifelong process that you need to continue as long as you expect to sell products. Recent trends or the buyer’s behavior may change over time and you’ll need to be prepared for this. That’s why you should never stop optimizing your product page and constantly search for new opportunities. Once you stop, your sales will start to die out.
