What is a keyword?

Before explaining how to find profitable keywords, it’s useful to clarify that a keyword is a key term composed of one or more words that reflect a user’s search on a search engine.

That’s why keyword research is crucial in SEO Optimization of web pages and ranking a product high on a marketplace to increase sales chances, such as Amazon.

There are different types of keywords and they are mainly divided by search intent.

  • Informational keywords: keywords that users type when they want to find information.
  • Transactional keywords: searches that express an intent to purchase, such as downloading or buying something.
  • Navigational keywords: keywords that presuppose the intention to find a specific brand, website, or business.

Keywords can also be divided based on the number of words they contain.

  • Vanity keywords: keywords composed of only 1 or a maximum of 2 terms that only generically describe a topic. These keywords have a high search volume and, therefore, high competition.
  • “Middle tail” keywords: composed of 2 or 3 terms with lower search volumes.
  • “Long tail” keywords: very specific keywords, composed of 4 or more words with low search volumes but little competition.

When searching for a keyword for selling, the relationship between average search volume and competition is crucial.  The profitability of a single keyword is determined by two main parameters: demand and supply.

Obviously, the higher the search volume, the larger the user base that can be reached; at the same time, however, on highly competitive keywords, there is also a lot of competition, making it more difficult to achieve results.

Therefore, in the search for profitable keywords, it is useful to focus on very specific keywords, with little competition, but that respond to search intent for niche markets or well-defined users.

This modus operandi also applies to doing SEO on eBay, as well as for other buying and selling sites.

How to find profitable keywords for a market niche?

A market niche is a sub-category of a market segment and is crucial in sales because it brings together similar people with common problems.

Therefore, if you decide to choose profitable keywords for a market niche, you will have these advantages:

  • Less initial competition and a higher conversion rate.
  • Decision-making power on pricing as users will have fewer price comparison options.
  • Lower marketing and advertising costs.

In analyzing a market niche, the first step is to identify your buyer personas and what they are searching for on the web.

Once the market niche is defined, you can leverage various tools to facilitate keyword research, and one of these is certainly SeoZoom.

With the “investigate sector” mode, you can discover a specific market niche within a sector or find niche products to invest in.

Through this tool, you can find new keywords that have low competition but good demand from users. The only problem with market niches is that they tend to saturate quickly, being very specific and restricted.

How to find profitable keywords for Amazon

If you’ve decided to use Amazon as a marketplace for selling your product, you cannot overlook the search for keywords for selling on Amazon.

Enhancing the visibility of your products through effective keyword strategies is crucial to increasing sales opportunities.

Given the enormous influx of users, Amazon represents an extraordinary opportunity for those who intend to sell their products online.

To make the most of Amazon, it’s essential that your products are positioned on the first pages of the search engine of the American retail giant.

Do not assume in advance that you know which keywords people will use to search for your products.

People often use the Amazon search bar in unexpected ways, and, most importantly, keep in mind that your perspective may be different from that of a potential buyer.

Unfortunately, Amazon does not have an internal tool to understand the search volume for a particular word.

For this purpose, there are a series of actions and tools that facilitate the search for profitable keywords.

Use Amazon’s suggestions

As a first step, you can use a tool indirectly provided by Amazon, namely, autosuggest.

Autosuggest is Amazon’s automatic completion, and the suggestions it provides in the search bar are not random but correspond to the most searched keywords by users browsing the marketplace.

To find profitable keywords, open Amazon in an incognito browsing window to get results unfiltered by your search history, and start typing the name of your product.

In the image below, the focus keyword is “drill,” and you will notice how Amazon suggests other similar keywords.

At this point, you have a set of keywords useful for better positioning your product, but you don’t know the search volume for these potentially profitable keywords.

Keep reading to understand how to obtain this crucial data.

Use the free sonar tool

Sonar is a free tool that allows you to get suggestions for likely profitable keywords for Amazon and also provides an order of magnitude for the search volume.

This site does not provide the exact number of monthly searches for each keyword but uses a scoring system, ranging from zero to five bars.

Sonar also allows you to expand the study of possible keywords for selling by giving additional suggestions compared to Amazon’s suggestions.

The best approach is to search again on Sonar for all the keywords indicated by Amazon’s autosuggest and gather all the data in a single table.

Additionally, another interesting feature of Sonar is the “extended” tab, which provides all synonyms and related keywords.

Discover the keywords of your competitors with Sonar

Sonar also offers the possibility to perform keyword research based on the products of your potential competitors using the ASIN code (Amazon Standard Identification Number).

It is a useful feature to discover the profitable keywords used by competitors who have managed to rank at the top of Amazon’s search.

Simply enter the ASIN into the relevant platform tab and start the search. The tool will show you the keywords for which that product has positioned itself on Amazon.

How to find profitable keywords for self-publishing

Self-publishing involves publishing and selling a book on an online marketplace.

One of the most profitable platforms for self-publishing is undoubtedly Amazon: thanks to its Kindle Direct Publishing program, it offers the possibility to publish a book and make it available for purchase worldwide.

The search for profitable keywords is undoubtedly the most critical step in self-publishing. As mentioned in the previous paragraphs, the profitability of a keyword is based on two main parameters: demand and supply.

A high-demand keyword is essentially a keyword that users often search for on Amazon Kindle and leads to a purchase.

The second element, namely supply, is very important to find profitable keywords with low competition. KPD Rocket is one of the most valid tools for quickly finding profitable keywords for self-publishing.

It is a paid tool that enables you to check if books on Amazon Kindle with certain keywords have satisfactory monetary returns and estimate the earnings of each book.

There are many paid online tools that allow you to perform this type of analysis.

Another very famous tool in the field of self-publishing is KDSPY, which, in addition to analyzing the sales potential of a single keyword, also suggests a series of long-tail keywords for a market niche.
