Planning to start a new blog in 2025, but unsure which niche will be most profitable? This guide walks you through the steps you need to take to choose a profitable blogging niche in 2025.

If you are starting a new blog in 2025, choosing the right niche is one of the most important decisions you need to make.

The blogging landscape has evolved dramatically in recent years – competition is fierce, and audiences are ever more discerning.

Picking the wrong niche can lead to frustration and failure.

Picking the right niche can set you on a path towards a highly successful and profitable business.

In this guide, I’ll walk you through the steps you need to take in order to choose a profitable blogging niche in 2025.

But first, why is niching down so important?

Why niching down is essential in 2025

The days of being able to succeed with a blog that covers everything and anything are long gone! And even trying to cover a broad niche like ‘food’, ‘travel’ or ‘money’ is pretty much impossible to do successfully with a new blog, in 2025.

If you want to succeed at blogging in 2025, you need to niche right down. Here’s why niching down is crucial…

A saturated market: There are now millions of blogs – you need to give people a solid reason to choose YOU over every other blogger out there. A narrower focus helps you stand out and attract your ideal reader.

It builds community: Niching down allows you speak directly to a specific group of people and build a loyal and engaged following. Niching down taps into people’s innate desire to be part of a community of like-minded individuals. Followers of niched down blogs are much more loyal and much more likely to come back again and again, as well a join your email list, buy your products and share your website with their friends and family.

SEO advantages: A tight niche makes it easier to rank on Google. Blogs which are really niched down often significantly outperform general ones in niche-specific search results. Being tightly niched really helps you ‘punch above your weight’ and rank for terms that would normally be out of reach due to strong competition from much bigger players.

Builds E-E-A-T and topical authority: Authority is becoming increasingly important if you want to rank in 2025 and beyond. And you cannot hope to be an expert on a wide niche like ‘food’, ‘travel’ or ‘money’. Niching down allows you to build topical authority and E-E-A-T quickly, which will help you rank on Google and outperform your more general competitors.

Build a brand: Ultimately niching down will help you build a strong, recognisable and trustworthy brand that your readers are more likely to click on in search results and go to directly, rather than via Google.

Monetization: You may think it would be easier to monetize a more general blog, but actually the opposite is true! Whether you plan to monetize via ads, affiliates, sponsored posts, digital products or services, niching down will lead to more income opportunities and higher pay-outs than trying to operate in a more general niche.

Still not convinced? Think of it this way… Imagine you are a new vegan searching for vegan cupcake recipes. Which blog are you more likely to read, interact with, sign up for the newsletter and even buy the recipe books from… A general food blog? Or a blog that specialises in vegan baking?

What factors make a blogging niche profitable?

Niching down is only half the equation. Just because a niche is tight does not automatically make it profitable. Not all niches were created equal. To choose a profitable one, you need to consider these key factors…

Market demand: Your niche should address a topic lots of people are searching for on Google. High market demand means more potential readers. That said, there are a lot of people in the world! You do not need to choose something with an enormous demand, just something that has enough people who are interested to get enough traffic to monetize.

Passive monetization potential: You ideally want to choose a niche that offers passive income potential. If you choose a niche that can only be monetized by non-passive income, your income will always be limited by the amount of time you have available. Whereas if you choose a niche that can be monetized via passive income strategies, like affiliate marketing, ads, and digital products, your income is much more scalable, as it is not dependent on the time you have available.

Audience willingness to spend: Pick a niche where the target audience is willing to invest in products and services to solve their problems. This is important. In some niches people are willing to pay thousands to solve their problems. In other niches, people are not willing to part with any money. This is not just a consideration if you plan to monetize via affiliate products and/or your own products and services. If people in your audience are not willing to spend money, advertising RPMs will be low and it will be nigh on impossible to get sponsored posts and collaborations.

Low competition: The less competition there is in your niche, the more likely you are to succeed. Targeting a low-competition niche makes it easier to rank in search engines and attract organic traffic. This is another good reason for niching-down. Competition in broad niches is fierce, but competition in tight niches is often much lower.

Evergreen content: Choose a niche that will still be relevant in 10 years’ time rather than one tied to fleeting trends. A blog based on a current trend may grow quickly at the start, but your entire income could disappear overnight when that trend is superseded by something new.

Your expertise: Writing about something you’re knowledgeable in increases your credibility, makes it easier to rank on Google and it makes content creation quicker and easier. It also makes it easier to sell products and services – and to charge more for them too!

How to choose a profitable blogging niche step by step

1. Identify your areas of expertise

Start by reflecting on your current knowledge and skills. What topics are you naturally good at or have existing expertise in? Write down a list of potential ideas.

If you feel like you don’t have any expertise, a good trick is to think about what your friends and family always want to pick your brains about. Or ask them directly what they think! You probably have expertise in more than one thing, but because you are good at it, you probably don’t realise just how much you know. (Or how much other people don’t know!)

And you don’t have to be a world-renowned expert in the topic! You just need to have a good amount of knowledge and ability in the topic to be able to help others who don’t. Though of course, if you do have qualifications and a lot of experience in your chosen topic, that’s even better!

If you really, really don’t think you have any expertise in anything, you will need to gain some sort of expertise first, before starting your blog. The days of being able to start a blog on a topic you know nothing about are long gone! Think about what would you be willing to learn and what you could learn fast.

2. Research market demand

Use a keyword research tool like KeySearch to evaluate demand for your niche ideas. Here’s how:

Type in topics you’re considering writing about: I don’t mean the ‘niche’, I mean the actual blog post titles you are considering writing about in that niche. Type those blog post ideas into the keyword research tool and look across at the volume score.
Look for a search volume of 100+: As you type in your ideas, look for volume scores of at least 100, there should also be plenty of volume scores in the 1000s too. If you find every idea you can think of has a low volume score, you may need to go back to the drawing board.
Check if there’s enough variety: Another thing to check is that there are enough things to write about on the topic you have chosen. You need to ensure you won’t run out of content ideas in a year or two’s time!
Use your common sense: KeySearch is not the only tool you should use. You should also use your common sense to assess whether people are actively searching for solutions in your niche!

3. Assess competition

Competition is inevitable, but some niches are so fierce, they are almost impossible to break into, while others have much less competition and it is still possible to rank, even if you are new.

Again you can use KeySearch to assess the competition. As you are looking at the search volumes, look also at the keyword difficulty (KD) score. Ideally you want to see lots of keywords in your with a difficulty (KD) score of 39 or lower.

You should also check the SERP analysis over on the left-hand side. This tells you the domain authority (DA) of the blogs which are currently ranking on page 1 of Google for that search query in question. Look for low the presence of low DA blogs ranking for the blog post titles you are typing into KeySearch. If you see blogs with a DA of 20 or below are performing well, there’s likely room for you too.

4. Evaluate passive monetization potential

Consider how your niche can be monetized through passive income sources, like ads, affiliate marketing, and digital products.

Of course, you can start by using your own knowledge and common sense here… Think about the target audience of the niche you are considering entering. Do those people typically have a lot of money? And are they willing to spend their money on solutions to their problems?

Another thing you should do is research existing blogs in your niche and look for evidence that it is possible to earn money from passive income sources. Do blogs in your niche have ads? Do they recommend products and link to those products? Do they mention their blog contains affiliate links? Do they sell their own products? And do they have evidence that they sell a lot of those products and make good money from them?

A good way to find these blogs in your chosen niche is to click on the results in the SERP analysis in KeySearch, for the blog post titles you are considering writing. These are your direct competitors and this will show you whether your direct competitors are able to make money in the niche you are hoping to enter.

5. Consider how evergreen your topic is

Ask yourself if your niche will still be relevant in 5 or 10 years’ time. There is no point in entering a niche that may not exist next year!

While it’s fine to incorporate trends, your core content should focus on evergreen topics that will help you build a long-term business and earn a good income for many years to come.

6. What are you passionate about?

Your passions should not be your first consideration. After all, you won’t get very far writing about something you are passionate about, but which has low search volume, fierce competition and which you have no real knowledge or expertise in.

But while passion isn’t the most important factor, it does matter. Blogging is a long-term commitment, so you need to choose a niche you won’t get bored writing about. Ask yourself: “Would I enjoy writing about this every week for the next 10 years?”

Pro tips for choosing your niche

So you have chosen a tight niche and it’s passed the 6 tests above. Here are some ‘next-level’ tips to help you get your blog off to the best possible start…

Keep your domain name general: This gives you flexibility to pivot if your chosen niche isn’t as profitable as expected.

Focus on sub-niches: Look for underserved sub-niches within your chosen niche for a competitive advantage. Build up topical authority in a few small sub-niches and you can branch out later to cover more aspects of your main niche when you are seen as a go-to expert in those small sub-niches.

Leverage emerging trends: While you shouldn’t build your entire blog on a short-lived trend, writing a few blog posts about a brand new trend in your niche can give you a real traffic boost in the early days and help you leap-frog your competition. Don’t overdo this strategy, though. The majority of your content should be on e vergreen topics.

Monitor and evolve: Continually assess the profitability and relevance of your niche, and adapt as needed.

Conclusion

The days of being able to write a general blog that covers multiple topics may be long gone, but there are still plenty of profitable blogging niches in 2025.

To succeed at blogging in 2025, you need to choose a tight niche that you have some degree of expertise in (or where you are willing to get that expertise ASAP!) You also need to ensure your chosen niche has a large enough audience, not too much competition and passive income potential. And you need to ensure that your chose niche has long-term potential.

Choosing the right niche can make all the difference in building a sustainable and profitable blog. By following the steps outlined above, you’ll set yourself up for the best chance of success.
