How to Pick A Niche For Your Blog (The Complete Beginner’s Guide)

If you’re staring at a blank page trying to figure out what your blog should be about, I want to start by telling you what not to ask yourself.

Don’t ask “what kind of content goes viral?” Don’t ask “what niche makes the most money?” Don’t ask “what’s trending right now?” I asked every single one of these questions between 2012 and 2018, across four different blogs, and made a grand total of £2.50 from accidental Adsense clicks in six years.

That’s not a typo. Two pounds fifty.

I started with a makeup blog. Then personal finance. Then a vegan blog. Every single time, my plan was the same: write a load of good, funny, well-structured articles, and somehow make millions of pounds.

That’s not, in fact, a strategy. That’s a wish.

The niche, I eventually landed on (houseplants) is the one that took me from £2.50 in six years to $3,000 a month within eighteen months. The difference wasn’t talent. It wasn’t even effort — I’d been working hard the whole time. The difference was that I finally asked the right questions before I started writing.

This article is that list of right questions, in order, the way I wish someone had handed it to me in 2012.

What Makes a Good Blog Niche?

A good blog niche sits at the intersection of four things: you have genuine insight into it, real people are searching for answers within it, you can sustain it long-term, and it’s sized correctly — not so broad you drown, not so narrow you run out of road. Most beginners only check one of these (usually “do I like it?”) and skip the other three, which is exactly how I ended up with four failed blogs before my fifth attempt actually worked.

Let’s go through each one properly.

Do I Have Unique Insight Into This Niche?

You don’t need formal credentials to blog about something — you need lived experience, genuine curiosity, or a problem you’ve personally solved. “Unique insight” doesn’t mean you’re the only person who knows this topic. It means you have a specific angle, a specific set of mistakes you’ve made, or specific knowledge that the average searcher doesn’t have yet but wants.

Here’s where I got this wrong with my vegan blog: I liked writing about veganism, but I didn’t actually have anything useful to say. I didn’t enjoy developing recipes. I didn’t know much about nutrition. I was just yapping into the void about a lifestyle I’d recently adopted, with nothing concrete to teach anyone.

Compare that to personal finance, which I’d actually abandoned for the opposite (and equally wrong) reason — I assumed I needed credentials I didn’t have. But I was frugal because I was working a minimum wage job at a restaurant. I had real, tested, useful things to say. I just didn’t trust that “I’ve actually lived this” counted as expertise.

It does. It’s often more valuable than a textbook qualification, because you can speak to the actual problems real people are having, not the theoretical ones.

Sure, I couldn’t be recommending credit cards (which was where the big bucks were at the time), but I could be developing cheap-ass nutritious meal plans (and vegan to boot) and compiling lists of free stuff to in my area. A frugal vegan in North Yorkshire? THAT is a niche.

Ask yourself:

• What have I taught myself out of necessity, not because I planned to?
• What do people ask me for advice on, unprompted?
• What mistake did I make and figure out how to fix?

Do NOT underestimate how few problem solving skills other people have. People are busy and stressed and you have what they need.

Does This Niche Have a Problem I Can Actually Solve?

The best niches aren’t built around topics — they’re built around problems. People don’t search Google because they’re bored. They search because something is wrong, confusing, or missing, and they want it fixed.

This is the single biggest shift in how I think about content now versus 2012. Back then I thought a “niche” was a subject — makeup, finance, veganism. Now I think of it as a problem space (yes, I know it sounds wanky, but we move).

Houseplant owners have a problem: their plants keep dying and the internet’s advice is either contradictory or written for people with greenhouses, not a windowsill in a rented flat. Also, we live in a capitalist society and people want what they can’t have. If your niche is rabbits and your readers want to keep rabbits outside in a hutch it’s your job to tell them no.

If you can’t name the problem your niche solves in one sentence, you haven’t found your niche yet — you’ve found a topic, and topics don’t rank.

Can I Talk About This Forever (Or At Least For Years)?

Pick a niche broad enough that you won’t run out of things to say after twenty articles, but specific enough that you’re not competing with sites that have a hundred staff writers. I call this the “could I yap about this forever” test, and it’s deliberately informal because the formal version (market sizing, competitive analysis) misses the actual point: can you, specifically, sustain genuine enthusiasm and find new angles for years?

Before you commit to a niche, plan out your website structure. Ideally, you want to be able to build a ‘complete’ site – i.e. most topics are covered – in about 60 articles. If you can’t think of that many, you need to rethink. If that’s almost too easy, I mean, awesome, but maybe consider niching down further.

This is also where seasonal or trend-driven topics fall down. It’s fine to cover something currently popular, but stay away from niches that need daily or hourly updates to stay relevant (breaking news, viral trends, anything tied to a single news cycle). Evergreen content is what lets you build a backlog that keeps earning while you sleep — which is the entire point of a niche blog over, say, a newsletter or a social account.

Is My Niche the Right Size?

If your niche is so broad that you can’t out-rank established sites, niche down. If it’s so narrow you can’t find 50+ article ideas, niche up slightly. Getting this sizing right is honestly one of the hardest parts of the whole process, and I’ll be transparent: I got it wrong even with my successful blog.

Houseplants, as a niche, is enormous. I built a genuinely profitable site on it, but I was competing with huge, well-resourced sites for a lot of my best keywords, and there are entire sub-topics I never got to properly because the niche was just too big for one person. As a result, a few, totally distinct articles drive the majority of traffic and link juice is not flowing. It’s fine (she says, whilst rocking in a dark corner).

So for my second site, I’m deliberately niching down to just pothos plants. Not houseplants. Not even “vining houseplants.” Pothos. Specifically. It sounds almost absurdly narrow until you actually do the keyword research — there’s real search volume, a genuine misinformation gap (a lot of pothos advice online treats them as boring beginner plants, when actually they can develop huge, dramatically fenestrated leaves that most owners never see because they don’t know it’s possible), and I’ve got six years of hands-on growing experience to draw from.

The lesson: bigger isn’t automatically better. A smaller niche you can dominate beats a huge one where you’re permanently fighting for scraps.

FYI, picking the right sized niche makes SEO a waaay more natural process. Everything will link together naturally. Especially important if the acronym strikes fear in your heart.

You can always niche up later.

Where Will My Images Come From?

Decide your image strategy before you pick your niche, not after — Pinterest* is a visual search engine, and a niche you can’t photograph or illustrate is a niche that’s much harder to grow. This one catches almost every beginner off guard, including me.

You don’t need to be a great photographer (I am not, and I never will be — I once spent £335 on a Canon 600D because every YouTuber had one, and my photos still looked like a crime scene). But you do need a plan. That might mean:

• Real photos of your own (plants, food, products, spaces)
• Screenshots (software, finance tools, templates)
• Infographics and custom graphics (Canva makes this genuinely easy, even with zero design background)
• Stock photography, used sparingly, for supporting images only

If you can’t picture how you’d create even basic visuals for your niche, that’s worth solving now, not three months in when you realise your Pinterest strategy has nowhere to go.

*You don’t have to use Pinterest, but I highly recommend picking a niche that is represented on the platform. Just in case it’s an avenue you wish to explore in future. Just pop your proposed niche in the pinterest search bar and see if anything pops up.

Are People Actually Searching For This?

A niche with no search demand is a diary, not a business — you need to confirm real people are typing real questions into Google and Pinterest before you commit. This is the step I skipped on every single one of my four failed blogs. I wrote what I felt like writing and assumed an audience would simply appear.

It doesn’t work like that. I’ll cover the full keyword research process in a separate guide, but at the niche-selection stage, you’re just doing a sense check:

• Type your niche into Google’s search bar and see what autocompletes
• Check if there’s a “People Also Ask” box on the results page (a sign there’s genuine question-based demand)
• Search the niche on Pinterest and see whether real boards, pins, and engagement already exist

If you’re met with silence on both platforms, that’s a signal, not a dealbreaker — but it does mean you’ll need to dig deeper before committing.

Can I See a Path to Making Money From This?

You don’t need a perfect monetisation plan before you start, but you should be able to picture at least one realistic income stream — ads, affiliates, or a digital product — for your niche. I want to be honest with you here: when I started Planet Houseplant, I had no monetisation strategy beyond “put ads on it eventually.” It worked out, but I left money on the table for a long time because I hadn’t thought further ahead.

You’ll likely make money from a mix of:

• Display ads (passive, kicks in once you have consistent traffic)
• Affiliate links (recommending tools, products, or services your audience already needs)
• Your own digital product (this is exactly what I’m doing with the ebook version of this site — “Just Tell Me What to Do” exists because I kept explaining this process to people one-on-one and realised it needed to be a proper, structured product)

You don’t need to pick one now. You just need to confirm at least one of these paths genuinely exists for your niche before you spend months building on it.

Quick Self-Check: Is This Niche Right For You?

If you can answer most of these with a confident yes, you’re not just picking a topic. You’re picking a niche — which is a completely different, much sturdier thing.

What If I’m Still Stuck?

If you’ve worked through every question above and still can’t land on a niche, the problem usually isn’t a lack of options — it’s too many half-formed ideas competing for your attention, or not enough structure to evaluate them properly. That was genuinely my situation more than once. I didn’t lack ideas. I lacked a process for testing them.

That’s exactly why I built the free Niche Finder Worksheet — it walks you through a passion audit, a demand check, a monetisation test, and helps you build an actual niche statement at the end, rather than just a vague idea floating around in your head. It takes everything in this article and turns it into something you fill in, rather than just think about.

Frequently Asked Questions

How long should it take to pick a blog niche?
Give yourself a few days to a week of focused thinking and research, not months. Endless deliberation is often a form of procrastination dressed up as caution. If you’ve genuinely worked through the questions in this guide, trust your answer and move forward — you can always adjust later, the way I did when I niched down from houseplants to pothos.

Can I change my niche later if I get it wrong?
Yes, and many successful bloggers do exactly this. I went through four niches before houseplants stuck. The earlier you catch a mismatch, the cheaper it is to pivot — which is another reason not to overthink the initial decision into paralysis.

Do I need to be an expert in my niche before I start?
No. You need genuine insight, curiosity, or lived experience — not formal credentials. Some of the most useful content comes from people slightly ahead of their reader, sharing what they’re learning in real time.

What if my niche idea feels “too small”?
Small, specific niches are often easier to rank in and monetise than broad ones, especially as a beginner with no existing authority. A tightly focused site that genuinely solves one group’s problem will usually outperform a broad site trying to be everything to everyone.
