Hi - the first thing to remember is that you will be expected to write a lot of content on your chosen niche, everything original, nothing copied and pasted. At least 2 or 3 articles per week, but preferably more. And a niche is not a product, it is a subject you can help a specific audience with

Therefore, it makes sense that it should be a subject you are genuinely interested in and have some knowledge of, or at the very least, would enjoy researching.

What would your friends and family say that you can talk about endlessly? Have you ever given advice on a particular subject?

You decide your own niche based on something you're interested in, passionate about or maybe even a hobby of yours.
