How to Choose the Right Niche for You
Here’s a simple three-question test:
- Do you care about this topic enough to write, talk, or post about it for a year?
- Are people already searching for this topic on Google, YouTube, or TikTok?
- Can you find at least 3 products or services in this niche that people pay for?
If the answer is yes to all three, you’ve found a niche with real potential.
Start with one platform—YouTube, blogging, email, TikTok, whatever fits your style—and one income method. Grow from there. Don’t try to build an empire in your first month.
Final Thoughts
In 2025, making money online isn’t just possible—it’s more accessible than ever. But the key is choosing a niche that balances what you love with what people need. The internet rewards usefulness. If you can solve problems, share what you know, and stay consistent, the money follows.
And remember: you don’t need to be an expert to get started. You just need to be one step ahead of someone else—and willing to learn.
