Chances are you have read at least once this quote: “Work smarter not harder!”.
This article will give you some hints to work smarter in choosing the most profitable niche even if this is the first time for you.

How to find the seed keyword for the niche?

Start from the major market categories such as:

Health and Fitness
Relationship and Dating
Self improvement
Wealth and money

These are those “evergreen markets” where the demand for products or services that solve problems never seems to stop.
Break down into smaller sub markets
Use free tools such as https://www.keywordtooldominator.com/k/amazon-keyword-tool
Paste the names of the markets into Keywordtooldominator to get a rough list of smaller markets, but this is not the niche that you search for.
Even if you got something more specific such as:

You need to refine this list a little bit further.
Using the list that you got from Keywordtooldominator you can insert the new keywords into any search box of major online retailers ecomerce site. Aliexpress, Amazon, eBay
In Amazon note all autofill suggestions which is aimed on what people want to buy and where they can find the item they search for.

Example of amazon autofill using “excel” as keyword.

Look for list such as: 10 Best Selling products on Amazon, Best Selling products on Clickbank.
Start with your seed keyword based on the product, information based product or service you want to promote to earn the affiliate commission.
Here it’s how I do the research to uncover the niche of an existing product that sells well:
Go to aliexpress and search "health and fitness equipment". Filter the results by criteria that interests you.
If you search for the newest product then it must be a product that could sell well for a period of time. We assume that the producers of that article did well their marketing research and they did uncover at least some unmet demand before launching it on the market.
If you filter your search by the orders received for a particular product then you know that you got an established market with a certain demand for that product.
Take the name of the first products that Aliexpress is showing you and do a research on Amazon.
If you find the product on Amazon you need to figure out if there is a good demand for it.
Next step is to find the niche of the product.
This can be done by reading people’s comments and product description.
Now look for the price range of the product.
Answer yourself the following questions:
How much can you earn from selling it?
Calculate the amount of USD you can get for each sale.
Read carefully the amazon affiliate Associates Program Policies and choose to promote those products that have a high demand, low competition (if any)
Is it worth to build an affiliate site for it with at least 50 articles with related content?
This is the product that I have used to check what niche is it for on Amazon:
Back Massage Magic Stretcher Fitness Equipment Stretch Relax Mate Stretcher Lumbar Support Spine Pain Relief Chiropractic
In this example, the seed expressions I used to discover potential niches in the health and fitness equipment sub market research were:

Back Massage Magic Stretcher
low back stretchers

Using https://keywordtool.io/search/keywords/amazon/ I got the following ideas for seed keywords:

low back stretchers
low back stretchers device
low back stretchers and decompression
ergonomic low back stretchers
low back stretcher sciatica mattress
low low back pain stretchers
low back trax back stretchers

What are the right search volumes for niche related keywords?

The search volume threshold to look for when selecting your seed keywords is related to the product you are trying to promote.
In adword keyword tool check
Competition - low
Top of page bid (low range)
Top of page bid (high range)

In the above example we can see that even the competition is low for the expression “keyword planner io” you need to pay up to $48.64 to be on the first page. This means that the market could be oversaturated and the ROI must be high. You need to earn at list $50 for each click to create a campaign using this expression.
In terms of number of average monthly searches even a threshold of 100-1k is good if you can have high paying products that cover the cost per click.
Use low search volume long tail keywords when you are trying to reach an easy ranking, which can have much higher conversion rate if selected properly.
Create helper articles using informational long tail keywords to leverage their power in low competitiveness and good search volume. This way you have established yourself as a good professional in the eyes of your readers. They will want to read more from you if they have found enough information in the informational articles.
Good informational articles will earn you the will to share your article from your readers. We all do this everyday. When we find articles with good and helpful content we are willing to share the link of that article with our friend that we know they have similar intersts.

What free tools can I use to create a list of related keywords for a niche?

The next step is to refine the list you got and extract only those expressions who will help you rank your article on the first page of major search engines whenever the user fires the search using the low competition high search volume long tail keyword you have used in your article.
Start with the most popular tools from Google - google trends and google related searches.

Google Trends -

to find the interest of people for the product that you are willing to invest time and money to promote. If it is a seasonal product then you should plan your campaign accordingly. You won’t push winter clothes during the hot summer because you won’t get the right amount of people interested into buying your product.
