Honestly mate, most of the replies already said it in different ways.
There’s no magic niche list that works for everyone. You’ve gotta do a bit of digging yourself. I usually start inside YouTube itself. Type a broad keyword and see what autocomplete suggests. That’s literally YouTube telling you what people are searching. Then check the results. If you see smaller channels pulling decent views, that’s usually a healthier sign than only massive channels dominating everything.
Google Trends is fine to see direction, but don’t rely on it alone. Some niches don’t look sexy on Trends and still print because the audience is consistent. Tools like TubeBuddy or VidIQ can help you sanity check competition and search volume, but don’t treat their scores like gospel. They’re just estimates.
Big thing people ignore is repeatability. Can you realistically make 50 videos in that niche without running out of ideas or hating your life? If you struggle to list 15 to 20 solid video ideas straight away, that niche might be too shallow.
Also think about monetization early. Not just AdSense, but is there something to sell later, affiliate, digital product, whatever. Some niches get views but the RPM is rubbish.
And yeah, interest matters more than people admit. If you’re not at least mildly into it, you’ll quit when views are slow in the first few months. And they will be slow. That’s YouTube for ya.
At the end of the day it’s less about “finding” a niche and more about testing one properly. Pick something with demand, manageable competition, and room to grow, then commit long enough to see data. Most people just hop every two weeks and blame the niche.
Do the boring research, back yourself, and give it time. That’s usually the difference.
