Niches are endless. If the goal is to make money, you need to focus on videos that generate the highest ad revenue.
For example:
- 1-hour pimple-popping videos generate good revenue.
- American TV shows and movies generate good revenue. In the past, Judge Judy, Bob the Singer, Spanish TV episodes, and many other types of content generated extremely high revenue.
- Car-related videos are another good niche.
If you are creating original videos, you need to have some actual skill or expertise in a particular area. Not everyone can create every type of content successfully.
For example, travel videos generate good revenue, but you need to have the skills to create good travel content.
And when researching a niche, one of the first things I recommend is checking whether the channels you are using as examples are actually monetized. You can check this with "TuberLife YouTube monetization checker" before using a channel as a reference.
