1. Google Trends


Google is so far the most used search engine with a 92.4% market share. Google Trends tracks the popularity of search queries across the engine, allowing you to analyze both emerging topics and queries as well as long-term trends.

This tool lets you filter across properties, compare search terms and topics, and even find related searches. While it's relatively well-known as a tool, lots of people fail to put their niche site ideas or keyword ideas into Google Trends to assess its potential. Here's how we recommend doing that.

Use Google Trends to find a niche

The most powerful strategy that you can use to discover interesting niches on Google Trends is to focus on specific geographies instead of country-level statistics. It will help you to find trends that may be starting locally but have the potential to expand into other geographies.

This is exactly how you get in on the ground floor of a niche that's forming.

Here's an example:


Vanlife, the concept of converting a van into a livable space, exploded during the pandemic. But as you can see, it hasn't taken off everywhere – yet. This trend is strongly concentrated in the Western US, but with a degree of interest all over the country.

Limitations of Google Trends

Although Google Trends is one of the best niche research tools, it has limitations. One of the biggest limitations is that it shows you relative numbers and not absolutes.

So even if two terms rank at 100, it doesn’t mean they have equal demand.

In Google's words:

A higher value means a higher proportion of all queries, not a higher absolute query count. So a tiny country where 80% of the queries are for "bananas" will get twice the score of a giant country where only 40% of the queries are for "bananas".

This proves true in our "Vanlife" query - as, even if it got an interest of 100 in Colorado, that doesn't mean the state is experiencing a housing crisis thanks to mass move-outs and RV rentals. It just means it's at peak popularity compared to other US states.

With any tool, you’ll want to validate your niche in other places and conduct competitor research before you pursue it. 

2. Google Search Console


Google Search Console is a free SEO tool by Google itself that will show the keyword you rank for and the number of page impressions that come from each keyword. It's a standard tool in the arsenal of SEO professionals, and something you're already doing.
But did you know that you can find niche ideas and keywords within your own website that your competitors will have a hard time finding?

Use Google Search Console for niche research

If a keyword has zero-volume or low volume in search then it doesn't mean that people aren't interested in it. In fact, you’ll see that people are indeed interested when you consider the number of impressions and clicks a zero-volume keyword receives. 

When you have a zero-volume search word or term with a relatively high number of impressions, you’ve may've found a niche gold mine. These are likely keywords that your competitors are not targeting because standard tools haven't picked them up. Which means you’re a shark in blue waters. Here's how to do it:

  1. Go to your Google Search Console's "Search Results" search
  2. Using a tool like Keywords Everywhere, export your Query data next to the search volumes provided by Keywords Everywhere
  3. In a Google Sheet, filter by zero search volume and sort by impressions or clicks.
You can use the tool to find an appealing niche by splitting out topics from your existing property into their own niche based on which keywords you are already ranking for, but SEO tools like Search Console show zero-volume terms.

Limitations of Google Search Console

While Google Search Console is an extremely helpful tool to analyze your own traffic and impressions, focusing on low and zero-volume search terms is still a gamble. Some zero-volume words are actually zero-volume and won’t yield any results. But with the help of this tool, you can write about the topics that will help you to complete your topical authority on Google.

3. Answer The Public


Answer the Public is a tool that shows you lots of search queries, specifically those in the form of a question (e.g. who, what, when, where, why, how). You can use these queries as long-tail keywords for niche markets and gives you an idea of related search queries for a topic.

Use Answer the Public for niche research

For example, searching the term "email marketing" shows that people who look into email marketing are also looking for information about direct mail, Facebook ads, and software tools. You can use these queries and target these less-competitive related keywords to grab a foothold in the market.


As Google Search Console, you can use Answer the Public to find search queries (including those with low or zero volumes) that help determine a worthwhile niche. This is similar to the topic of using “People Also Ask” to help find undiscovered search terms. Essentially you’re taking a peek into the psychology of what people are asking when they’re thinking about a particular topic.

PRO TIP: Not every question shown in "People Also Ask" are actually...asked by people. Many of these are generated by subsections of articles that appear on Google, as proven by creating articles on novel topics. 

Limitations of Answer the Public

You only get a couple of free searches per day. So if you're not looking to spend money on tools and you have a lot of searches in mind, our next item on the list is likely to help.

4. Answer Socrates


Answer Socrates is an alternative to Answer the Public with unlimited free searches. It combines information from People Also Ask, Google autocomplete, and Google Trends. Instead of showing the information in a sort of tree shape, Answer Socrates groups responses based on the question word. Here's an example.

How to use Answer Socrates for niche research

It's as simple as putting your seed keyword into the tool and seeing which questions come up. This is a great way to discover buyer intent keywords you can write buying guides for.


5. Similarweb

Similarweb is mostly used as a traffic analysis tool, which, unlike keyword research tools, also tries to tell you how much traffic a given website is receiving from non-organic channels like Direct traffic and referral traffic.


How to use Similarweb for niche research

If your strategy for acquiring traffic is purely SEO, but your competitors are receiving most of their traffic through referral or direct sources, this could be an indication that search demand for the topic isn't very high. For example, news websites tend to have a higher share of direct traffic, and eCommerce stores (especially with affiliate programs) have more referral traffic. 
This doesn't mean it's not possible to tackle the niche, but you might want to find other competitors to model your efforts after if the big players are getting their traffic from sources you can't easily replicate.

6. Subreddit Stats


Reddit is one of the hotbeds of niche communities, and Subreddit Stats is a platform that provides ranking lists, subscriber trends, and other statistics for popular forums on Reddit. The platform also identifies top keywords and related niche subreddits, making it a great place to find content gaps in your industry.

If you’re seeing the same question, again and again, that’s a good sign because you’ve found an active niche community that would consume your content if you answer their questions.

Use Reddit to find a niche

By using Subreddit stats, you can look at subreddits that are exploding in popularity. Here's an example of a niche we found using this free niche research tool:


The subreddit r/podcasting has doubled in subscribers over the last two years. The most frequently asked questions related to podcasting gear and audio-editing software, both of which can lead to great commissions. With so many people starting podcasts during the pandemic, it's not surprising at all to see this surge. 
But your job is to decide whether you think it will hold up. 
The nature of Reddit means that topics can blow up very suddenly but can also die off just as quickly. So, always look for questions with a lot of replies and use keyword research tools to validate them.

7. Exploding Topics


Exploding Topics is a platform that provides insight into trends before they become trends. You can explore topics by category and period to give you insight into search numbers and growth. The platform classifies topics as “exploding” based on its growth trend.

How to use Exploding Topics for niche research

You can start by visiting the homepage and seeing which trends the team has selected. Exploding Topics also has a free newsletter, as well as a "Pro" version where you can see all the topics that are hidden on the homepage.


Limitations of Exploding Topics

If you find an exploding topic that sparks your interest, use SEO tools to validate that it’s an upward-trending market (and not just a fad). 
Like Google Trends, Exploding Topics is best used as a starting point. It’s great if you’re looking for ideas or want to catch new trends in your niche. If you’ve already narrowed down your direction, you’re better off using other tools that search capabilities. Also keep in mind that even if a topic isn’t “exploding”, it can still be a worthwhile and highly monetizable niche.
