How to Choose a Blog Topic with Earning Potential? Niche and Competition Analysis

There are blog ideas that sound great… until you start managing them. You write for three months, upload texts to groups, hope for SEO – and then it hits you that no one will click an ad next to a text about how to drink nettle in the spring.

It’s not about abandoning your passion – but about knowing from the start where the money is. And how to combine it with what you know, like, and can talk about. You don’t need to be a marketing genius or have a degree in economics. You only need a strategy that will allow you to start off right – not by guesswork.

Blog topics are not “write about your passion” – rather an analysis of three things that truly matter

Let’s start with the basics: a well-chosen blog topic should meet three conditions. This is no coincidence – it’s a specific strategy we’ve provisionally called the “Golden Niche Triangle”. What does it consist of?

• Financial potential – are there rates in this industry that allow you to earn from ads, affiliation, products? (is RPM 1 zloty, or 50 zloty?).
  
• Gap in competition – is the topic already covered by giants, or is there still room for you to get in?
  
• Unfair advantage – do you have something others don’t? Industry knowledge, experience, a unique voice, access to specialists?
  

If even one of these elements is missing, it will be tough. Sure, you can write a blog about living in Skarżysko-Kamienna or snail farming – but if no one is looking for it, no one clicks on the ads, and competition is zero because no one needs it, there won’t be any earnings.

The blog’s topic must combine real demand with your execution potential. If you see money there, but have no idea about the industry – you’ll be researching for months. If you know something excellently, but there are no advertisers – you won’t earn. A well-chosen niche is not a compromise. It’s a place where everything connects.

The topics of blogs that will earn in 2025 are not about trends – but about the money behind them

Before we start brainstorming blog names and content plans, it’s worth stopping and answering one question: is anyone in this niche paying for the audience’s attention? Because if they’re not – it doesn’t matter how well you write.

Here are a few blog topics with the biggest earning potential in 2025 – and no, they are not “fashion” and “lifestyle”:

• personal finance – RPM (income per 1000 views) even 40–70 zloty,
  
• marketing and SEO – affiliation + high rates in AdSense,
  
• vocational education – courses, e-books, consultations = high margins,
  
• business and making money online – ideal for promoting your products,
  
• technology, AI, tools – often well-paid B2B campaigns.
  

What do these niches have in common? High CPC (cost per click) and the presence of advertisers. That’s where the money spins – and it’s not just about AdSense. You have room for affiliations, digital products, sponsored newsletters. If your blog touches on a topic, someone would spend money on in Google Ads, that means it’s a good path.

Your blog is not a diary – it’s a sales vehicle. Reverse your strategy and earn from the first post

If you start with writing, without thinking about the money – you will probably lose a few months and return to square one. It’s the brutal truth, but most blogs fail not because someone wrote badly, but because they wrote about something no one needed.

That’s why it’s worth reversing the classic scheme. Instead of:

1. starting a blog,
   
2. coming up with a topic,
   
3. writing content,
   
4. thinking about how to monetize it.
   

Do this:

1. find a product/service you want to recommend or sell,
   
2. look at what topics people are searching for in this niche,
   
3. plan content that will solve their problem (and be SEO-ready),
   
4. only then start the blog.
   

Such a model allows you to earn from the first post. Because you’re not writing to “develop” – but rather so someone will click, read, buy, or sign up. And no, it doesn’t mean the blog loses its soul. It means that you know whom you’re writing for and why.

The topic of the blog matters… but so does your name. YMYL can kill a blog if you don’t show who you are

From 2023 onwards, Google increasingly filters content that concerns money, health, law, and life decisions. If you’re delving into these topics, you must prove that you are a person with experience or knowledge. Otherwise, your blog will disappear from search results – even if you write well.

This is the YMYL principle – Your Money or Your Life. In short:

• if the blog concerns health, finance, education, law, psychology – Google requires authority,
  
• if there is no “About the Author” section, no contact information, no context – the algorithm will not trust you,
  

How to protect yourself:

• add an “About Me” section with specifics: who you are, why you write, what experience you have,
  
• sign your texts with your name and surname (or a pseudonym with a backstory),
  
• if you can – show your face, social media, links to external publications.
  

In sensitive niches, it’s not enough to write well. You also need to show that you have the competence to advise others.

FAQ

Can you still make money from blogging?

Yes – but you have to approach it as a project, not a diary. A blog earns if:

• it’s in a well-chosen niche,
• it has traffic from Google or social media,
• it offers something specific: a product, affiliate link, newsletter with an offer.

Writing “for yourself” is a nice start, but money appears only when someone wants something from you.

Can I write about what interests me?

You can – but if your interests do not meet real demand, it will be difficult. Instead of giving up your passion, find its intersection with people’s needs. Do you like books? Create a blog about how to earn as a copywriter. Are you into fashion? Make a blog about business style for women over 40. It’s still you, just with a plan.

How many visits do you need for a blog to start earning?

It depends on the model. For example:

Google AdSense – decent earnings from 10–20 thousand unique visits per month

Affiliation – first commissions can come in with 300–500 visits if you have a well-chosen offer

Your own product (ebook, consultations) – you can earn even with 1,000 visits, if you have a niche audience and a specific problem to solve.

Is it worth blogging about fashion, beauty, or lifestyle?

These niches are very competitive and it’s hard to get through SEO. But if you have a unique point of view, strong social media, or a local approach (e.g., “capsule fashion for over 40,” “vintage style in Kraków”) – there’s a chance. However, you must remember that earnings from such blogs are more often based on collaborations than affiliation or advertisements.

Do I need to know about SEO to run a profitable blog?

Initially – no. But if you want to earn in the long term, it’s worth grasping the basics: keywords, text structure, internal linking, titles. Without this, it’s hard to expect traffic from search engines, and without traffic… there’s not really anyone to sell anything to.
