Lesson 7: Evaluating a Sub-Niche (Part 1)

As you already know from the previous lesson, it’s not enough to choose a niche. You also need to think about a relevant sub-niche and micro niches.

Have you picked the particular niche? Now it’s time to check if there is enough interest in this topic. Steady interest is okay, but it would be perfect to find a niche with the increasing interest. 

Google Trends provides good insights into this metric. You can immediately get answers to two main questions:

  • Are people actually searching for your niche?
  • Is your niche receiving increasing or decreasing interest?

Let us take a look, for example, at Health niche. Diets are always in demand and a lot of people care about their health.

Just enter the keyword ‘diet’, choose a country and a time range. In my case, I will choose the United States and Past 5 years.

Pay attention to the country’s choice. Do you want to make a website for users from a particular country or over the world? If you want to create a site in English, then it’s still better to choose a target country. Sometimes it’s impossible to find a relevant product or service you can promote to the audience from all countries.

In our example, we see that the trend is stable enough. This sub-niche get spikes of interest due to being seasonal.

Have you noticed that interest increase early in the year? Do you have any ideas about why it is happening? One more hint: take a look at the example with the keyword ‘fitness’ below.


The answer is extremely simple. At the beginning of each year, people promise to change lifestyle for better health:)

Let’s go back to our Health niche. The sub-niche ‘diet’ is too broad, so we have to narrow it. Scroll down and find a block ‘related queries’ box. By default, there is a Rising category. Switch it to the Top.

Now we know that most people want to find a keto diet and paleo diet. If we take a look at other queries we will see that they are also interested in carb diet, military diet, protein diet, etc. Please note that there are only keyword phrases with the focus keyword ‘diet’. We have done so in order to make a more accurate comparison.

How to find the most popular query?

Let’s compare all these search queries and identify the most popular one. Open Google Trends in a new Tab and add other queries (click on the button ‘+ Compare’).

As we can see, a Keto diet (colored blue) is the most popular search query. However, the interest in this diet decreased, compared to the previous year. 

If we remove a Keto diet from our comparison, we will see that other results have the same interest over time.

That tells us Keto diet is a leader among other search queries, related to diets. Of course, there are many more keywords to check, so it is too early to make any final assessment. 

Let’s summarise. We chose the Health niche, specify a sub-niche and analyzed that the most popular micro niche is Keto diet. 

Now we are going to dig deeper into this micro niche. Open Google Trends in a new tab and enter the query ‘Keto diet’. This time the time range should be Past 12 month instead of Past 5 years. We need to understand what people are concerned about the here and now.

Take another look at the ‘related queries’ box. Write down all unique search queries, at least, 20 of them. We will use these queries to further research. You need to make the same list based on your chosen niche.
