Which Blog Niches Are Most Profitable in 2021

So you want to start a blog to generate some passive income for you or your family.

But you have no idea where to start?

Don’t worry – choosing a niche for your blog is where most affiliate marketers stumble and fall.

It’s actually why most new bloggers quit after just a few months.

And all because they didn’t pick a profitable niche – one with an audience that spends money.

I don’t want that to happen to you. So, I’ve come up with a list of profitable blog niches to help you on your journey.


Not All Niches Are Equal

There are tens of thousands of possible blog niches you could target.

But the reality is that some are worth more than others.

And what most first-time bloggers don’t realize is that roughly the same amount of effort is required to target a niche that can generate $10,000 per month as one that might only earn you $1,000 per month instead.

Basically, an extra 10% – 20% in effort and expenditure could be the difference between part-time and life-changing income.

So let’s take a look at which broad topics are the most profitable.


The Big 6 Blog Niches

Pretty much any sub-niche you can think of will fit neatly into one of these categories:

  • Health
  • Wealth
  • Happiness
  • Time
  • Love
  • Lifestyle

The above list is based on  Abraham Maslow’s ‘Hierarchy of Needs’, first published all the way back in 1943.

But marketers recognized its value almost straight away – it helped them identify exactly the types of products that would appeal to the broadest possible audience.

Humans are motivated by their need to first ensure their own personal survival, then build valuable relationships, before ultimately striving to become the best possible version of themselves.

The most successful niche sites tap into those patterns.

Because if you can solve a problem for your visitors they will happily pay you money for doing that.

That cash could come from them purchasing a product or service, paying for an information product, or simply clicking on a display ad (like AdSense) on your blog.

Remember, there’s usually more than one way to make money from a given audience so if affiliate products don’t work, then try display ads, etc.

Now that you understand the psychology behind profitable niches, let’s look at a few of the best in more detail.


Most Profitable Blog Niches

These are some of the 15 most profitable blog niches today. 

1. Personal finance

The average adult now carries around $30,000 in unsecured debt i.e. credit cards, plus personal and auto loans. 

This type of debt is multi-generational in that it spans Gen Z, Millennials, Boomers, etc. 

So that means there’s a massive potential audience of people who are eager to find products or services to help them get out of debt.

Personal finance blogs could promote student loan restructuring, micro-investing and savings apps, debt consolidation services, online banking, or even bankruptcy attorneys.

Commissions for personal finance products tend to be in the range of $50 – $150 per lead.

That’s why a successful personal finance blogger can expect to earn at least mid-5-figures per year. Euros on a black table

2. Cryptocurrencies

The last recession and previous economic downturns created the perfect stage for a new type of currency to emerge.

And in 2008 exactly that happened with the launch of Bitcoin thanks to the mysterious Satoshi Nakamoto.

Since then cryptocurrencies have taken the world by storm, most recently with the hype around Dogecoin and other popular Altcoins.

At the time of writing, cryptos have stabilized, with no major upward or downward activity but with a steady stream of new investors. 

(It’s worth mentioning that market experts predict the next Bull crypto rush will start somewhere around the end of 2023.)

So you have two years to become active in this niche promoting cryptocurrency exchanges, investment programs, peer-to-peer trading platforms, and hardware wallets.

3. Fitness

The global fitness industry is worth around $97 billion, with $22 billion of that spent in North America alone.

So, you have proof that people already spend a lot of money in this niche.

Now it’s a question of what sub-niche you choose because fitness itself is just too broad to tackle with one site.

The good news is that the fitness niche has tons of options such as:

  • Fitness trainer certification
  • Fitness equipment
  • Clothing
  • Home gym equipment
  • Suspension trainers
  • Fitness supplements

And they’re just a few examples of the different sub-niches within fitness.

One important note is that many health and wellness supplements operate affiliate programs that offer recurring commissions.

So you can sell once and get paid for several months.

Weight loss is a massive industry and a great blog niche.

4. Weight loss

This is quite possibly one of the most lucrative niches you can choose, but it’s also one of the most competitive.

The Western world is in the middle of an obesity epidemic with almost 1/3 of the entire population of the United States now classed as obese.

But the vast majority of overweight people don’t enjoy being fat.

So, this is an audience primed for hearing about how the information on your blog can help them drop those unwanted pounds.

There is a small overlap between the fitness and weight loss niches because the act of getting fit invariably means you lose weight but don’t let that stop you.

If you want to start a blog around weight loss you could focus on aspects like Keto and other forms of alternative eating, meal delivery services, gym gear, health supplements, online training programs, and exercise plans.

Commission rates in this niche vary from $10 per lead to $50+ per sale.

5. Dating/love

Humans are tribal creatures – we’re not designed to exist in isolation. 

That’s why prisoners are kept in solitary confinement as punishment.

It’s part of human nature to form a relationship with another human and have offspring.

That probably sounds very mechanical, but it’s the truth.

But there’s a problem. And, I’ll use a movie quote to highlight it; “We shop at home, we surf the Web, and at the same time we feel emptier, lonelier, and more cut off from each other than at any other time in human history…”

Simply put, most adults experience real problems when trying to find a date, never mind an actual relationship.

So if you truly believe you can help people find love, or even just companionship, then this might be a great niche for you.

Oh, and some dating sites pay up to $75 for every new customer you refer to them.

6. Privacy/safety

After you’ve taken care of having enough food to eat your next primitive motivation is to find safety and shelter at night.

Our need for safety and privacy is hard-wired into us – it’s not something we can ignore.

But what aspects of this human need can translate into a topic for a blog?

Well, if you start with the idea of physical safety then a popular and profitable sub-niche is home security systems. 

Or if you look at the need for digital or online safety and security, you could promote VPN services, identity theft protection companies, and even anti-virus software, for example. 

And finally, if we look at the need for being able to protect your own life and the life of your family, that leads us to sub-blog-niches like martial arts training, and home defense weapons.

7. Fashion

The first thing you need to know about the fashion niche is that it’s evergreen – people like to dress well even during times of war and economic turmoil.

Clothing is also a basic human need.

So blogs in this niche can expect consistent earnings performance, with seasonal spikes in sales, because nobody wants to walk around naked.

Again, this is a very broad topic so a site focused around a sub-niche will typically perform better both in terms of rankings and revenue.

You could set up a blog on organic fashion clothing, clothing made from recycled and sustainable materials, retro and vintage fashion, or plus-sized clothing, for example.

Just pay attention to the commission rate on offer before you sign up for an affiliate program.

Some fashion affiliate programs pay 20%+ per sale, but there are plenty of others where you’ll earn just 1% commission on all referred sales.

Remember, it requires the same amount of effort to promote an affiliate program that pays you 1% as it does to promote one that pays you 10%+.

That’s an easy way to 10x your site’s income without any increase in traffic.

8. Beauty

Human vanity is nothing new, illustrated by the fact that humans have worn some form of cosmetics for thousands of years.

So that makes this another evergreen niche – any market that has lasted for several millennia is likely to be around for at least the rest of your life.

In terms of the beauty niche you could take any of a number of paths with your blog:

  • Cosmetics reviews
  • Beauty tips
  • Skincare
  • Acne
  • Cruelty-free cosmetics
  • Artisan soaps
  • Perfumes
  • Haircare

There are other perks to starting a beauty blog, like getting free samples to promote a brand, or maybe even becoming a brand “ambassador” if you can drive enough traffic to certain affiliate offers.

And there’s also the fact that beauty products don’t last forever, so they need to be purchased over and over again.

So there’s the potential in the beauty niche for real long-term profits.dollar signs in the clear blue sky and a guy pointing to an ipad

9. Make money online

The Internet leveled the playing field for entrepreneurs.

Now anyone with a bright idea and a home computer could start an online business – you didn’t need staff or a physical store.

There was no need for bank loans or investors. 

This is exactly why there have been “Make money online” courses for as long as there’s been a public Internet.

It’s an extremely lucrative niche –  one that creates new millionaires on a daily basis.

That also means it’s extremely competitive, so any new blogger who wants to tap into the vast quantities of money circulating in the IM (Internet marketing niche) will need to play a long game.

But if you can gain traction with your own audience, commission rates of $500 per lead are not unheard of. You have to remember that many Internet and affiliate marketing courses retail for between $997 and $2997.

So the creators of these courses are happy to pay you a few hundred dollars for each new customer you send their way.

10. Insurance

Now here’s a niche that you’re not going to find mentioned in any other roundup of profitable niches to build a site around.

Even though it’s quite possibly the single most profitable blog topic out there.

Yes, it’s more valuable than the CBD, VPN, law, or how to make money online niches.

Insurance advertisers are willing to pay $15 – $60 per click with PPC ads to generate a single new lead for their business. 

And they do that because they know that the lifetime value of each customer is going to be 100x that.

One smart way to tap into this niche is to start a content blog on a sub-niche of insurance and then monetize it with display ads from AdSense, Ezoic, Ad Thrive, etc.

Your content will, however, need to be authoritative and professionally written to have any chance of converting visitors into clicks. 

Or you could choose to use affiliate marketing offers instead, where you can expect to earn anywhere from $10 to $30 per sale. 

An interesting and growing sub-niche within insurance is the pet insurance category.

That’s just a little insider tip for you.girl taking a class on a computer

11. Online education

This is another niche that’s often overlooked by affiliates who are looking to make big money with credit card offers or selling VPN subscriptions.

What they don’t know is that online education actually has a CPC value second only to insurance.

A typical online education company is willing to pay $12 per click for a new lead. 

That’s why affiliate programs in this niche are willing to pay up to $100 for each new student you refer.

You also have quite a bit of variety to work with in the online education niche because you could choose to promote online-only universities, language training programs, or even exam prep products such as for the SAT.

There’s even a sub-niche for selling exact prep guides for medical students and attorneys studying for their relevant exams.

Online education has also seen a real boom in popularity since 2020 and that doesn’t look set to change any time soon.

12. Parenting

385,000 babies are born every single day.

That’s 385,000 sets of parents who will need all the help they can get to cope with their new bundle of joy.

If you look at this from a problem-resolution point of view, new parents are willing to do anything to keep their kids safe, healthy, and happy.

So not only will this niche pretty much always have demand for products and services but useful information and advice also has a real value attached to it.

That’s why this industry is worth $88 billion in North America alone. 

And while this particular niche tends to be dominated by “Mommy Bloggers” there’s plenty of scope for Daddy bloggers to publish content too.

But there are tons of other sub-niches you could publish a blog around like reviewing kids’ toys, nerdy clothes for toddlers, general advice for new parents, child proofing your home, etc.

The one aspect of parenting you should steer clear of – for a number of reasons including Google rankings – is giving medical advice of any kind.

You don’t need to be religious to start a blog about spirituality.

13. Spirituality

This is another broad niche that you won’t find many affiliate marketing blogs talking about.

Some of that is because they only ever repurpose their competitor’s content, but there’s also the possibility that they don’t want hundreds of new bloggers competing with them.

Spirituality falls under the category of “self-actualization” in Maslow’s Hierarchy – the very top of the pyramid in terms of self-improvement.

So even though you might not have any interest in the subject, the need for spiritual fulfillment is a driving force for hundreds of millions of people around the world.

It’s also worth pointing out that when I say “spirituality” I’m not referring to formal religions. This niche covers everything from yoga and meditation to tarot cards, crystals, and psychic readings.

The concepts of universal ordering and the Law of attraction also fall under spirituality, and for those of you who don’t know, there’s a potential fortune to be made here.

Although there’s also a surprisingly profitable sub-niche in different types of prayers for different occasions and needs. 

What I’m saying is that you don’t need to be religious to start a spirituality blog.

14. Travel

This was one of the most profitable niches you could ever hope for before 2020 and I’m hopeful that it will be again.

Estimates predict, however, that the travel industry might not fully recover from recent events until late 2023 or early 2024.

So right now could be a good time to slowly build one in the background and be very well positioned when international travel returns to normal.hut in the woods

15. Survival

I left this one until last for two very specific reasons. 

Firstly, recent events have demonstrated that the average person should have at least one month of food stored at home in case of emergency.

So the “prepper” audience is now much broader than it was pre-2020 because you have to include everyone who learned the benefits of having spare food, water, and toilet paper to hand.

And secondly, the desire to stay alive is the single most powerful instinct a human being possesses.

So finding a way to tap into that very specific need could provide you with a very sizable income from your online business.

Also, prepping is the only niche where you can sell “suites” in an underground survival bunker for a 5% commission rate on an accommodation fee of $35,000 per person.


Wrapping it up

So as you can see there’s a profitable niche out there for pretty much anyone who wants to start a blog.

We didn’t include food as a separate topic because it falls under “survival”, plus food blogs are a dime a dozen i.e. there are millions of recipe sites so it’s a tough market to gain traction in.

Each of the examples provided above really only scratches the surface of what’s possible.

There are literally thousands of sub-niches you can leverage to make money blogging.

It’s just a case of finding which of the popular blog niches you most prefer. 

But as long as you stick to helping people find solutions for their problems, you’ll find that profit is never that far away.
