67 Profitable Micro Niche Blog Ideas to Start Generating Passive Income

by | Nov 4, 2021

Blogging has created internet millionaires since its inception back in the late ’90s.  As the internet becomes adopted worldwide, the market for bloggers continues to grow.  If you’re already familiar with blogging, you probably have a decent idea of a micro-niche for blogging.

If not, no worries! We will dive into what a micro-niche is.  Why you NEED to focus on a micro-niche if you’re new to blogging, and a few ideas to start turning the gears in your mind.

What is a Micro Niche?

Put simply, a micro-niche is a subtopic to an overarching theme or idea.  For example, “make money online” is an extensive, widely searched topic.  Someone deciding to start a blog about making money online won’t succeed unless they nice down and find a sub-topic to focus on within that niche.  Something like affiliate marketing, Amazon FBA, at-home side hustles, and dropshipping would all be considered micro-niches to the “make money online” niche.  Make sense?

Finding your niche dartboard

Keep in mind – some industries are already very niche; there’s no reason to niche down. Your crazy obsession with exotic cats doesn’t mean you need to start a blog just about Canadian Lynx’s.  Based on the competition, a blog about exotic cat ownership should be niche enough.  As you begin to research and identify profitable niches, you’ll quickly learn how much competition exists and whether your idea is feasible or requires a more narrowed focus.

Why Micro Niche Blogging? 

It’s every blogger’s goal to attain rankings at the top of the search engines.  The more phrases show up for in Google, the better chance you can drive traffic, generate conversations, and ultimately make sales.

Unfortunately, the internet is no longer a newborn baby.  In many cases, it’s a requirement to find a niche. Otherwise, your blog may struggle mightily to succeed.  Trust me, I made this mistake in my early days when I created a blog trying to rank for “fitness for men.”  Turns out ranking for that term would’ve been impossible at that stage.  Hence why that blog failed, mightly.

How to Find Micro Niches with Lots of Potential

Finding micro-niches is easier said than done.  Sure there’s a gambit of articles out there sharing their ideas for profitable micro-niches.  But guess what?  Everyone considering launching a blog is reading those articles, so how “niche” is it when everyone generates content around those topics?  This is when research becomes your best friend.

For the sake of time, we won’t dive in too deep on performing in-depth niche research. That’s what this article is for.  We will, however, give you a few short and sweet tips you can take immediately to start finding underserved niches.

You can find profitable, low-competition niches before we muddy the waters with all these remarkable tools.  Start with Google.  Search different keywords related to the place you’re considering and see what shows up.  Is the content Googles serving relevant to the phrase you searched?  Are the websites that show up large authoritative sites or small mom and pop blogs (easy to outrank)?  Lastly, see what terms Google auto-populates as you start typing your phrases into the search bar.  This can give you great ideas you may not have been considering!

Keyword Research Tools

Tools such as Ahrefs, SEMRush, and Ubersuggest give you detailed information about how specific competitive phrases rank online.  These tools are 3rd party crawler tools, so take what they provide you with a grain of salt.  However, this is a great place to start to get your gears turning.

Profitable Micro-Niche Blogging Ideas

As mentioned in the previous section, you should always be skeptical about picking a blogging niche mentioned in numerous posts as a micro-niche.   In researching hundreds of articles, we’ve discovered a few niches that time and time again show up.  Sure, there may be potential with some of these. Still, we’re going to skip over the commonly used niches and share with you only the golden nugget niches we were able to discover.

Here are a few niches that deserve recognition but ultimately didn’t make our list because they appear on every other micro-niche blogging post.

Some of these niches include: 

Phone gadgets, travel guides, movie/show reviewing

Additionally, after researching for profitable micro-niches in Google.  I realized many of the articles were not actually providing “micro-niches.”  Baby care, keto, bodybuilding, and home improvement, in my opinion, would be considered “niches,”  no “micro-niches.” So with that being said, below is a list of 67 micro-niches to start a profitable blog today.

If you want to run a legitimate business on the internet, branding is vital.  Take your time with this step and really find a name and logo you’re happy with.  Going through a complete rebrand is a lot of work, and it’s expensive.

Build a Blog Website

Now comes the fun part – building a blog website.  To launch your blog, you may be tempted to explore options like blogger.com, Wix, Weebly, or even Squarespace.  While all these options are fine and will do the trick, we recommend you get on WordPress.  WordPress is a content management system (CMS) that powers more than half the websites in the world! For bloggers, WordPress provides the most flexibility and doesn’t require you to know code.

Content Strategy

Your content strategy will steer what keywords you rank for and how people find you on the internet.  By using the research tools mentioned above, you can quickly identify high-volume keywords with little competition.  These are the keywords you’ll want to focus on to start getting rankings.

Think about what  ‘call-to-actions would make sense for your blog and start tailoring your content towards it.

Blog Marketing

‘If you build it, they will come.’ This famous quote from Field of Dreams doesn’t hold true in the world you blogging.  You need to actively market your blog to drive traffic.

Search Engines, Social Media, YouTube, and Email are familiar places to market your blog.  SEO is what drives (free) traffic from search engines.   Social Media allows you to target a specific audience – with the right message, you can create highly successful campaigns.  Lastly, email allows you direct communication with your customers. It is a necessary component to sell goods/services to your readers.

Blog Monetization 

Now the part you’ve been waiting for.  How is my blog going to make money? We’re glad you asked.  One of the most common methods of monetization is advertising.  Ad networks like Google Adsense allow you to place a banner ad on the site resulting in earned ad revenue.

Affiliate marketing is another standard method for monetizing a blog.  Once you have a large enough audience of readers, you can make recommendations for specific products. You receive a % of every sale made.

The number of methods to monetize a blog is extensive – but another means to earn a profit is selling digital products.  Ebooks and online courses would be examples of digital products.  This type of income is passive and can largely be automated.
