How do you know when a niche is too narrow?
In other words, everybody is talking about speaking to a very specific niche but I'm worried about going too narrow.
For example, let's say you want to make a cooking channel specifically about how to cook desserts with an instant pot, because instant pots are very popular right now etc and you start making content and in 1 year the instant pot falls out of fashion, then the entire channel is basically no longer relevant. If I make a channel just about cooking desserts it might not be narrow enough. How do you know when it's too broad or too narrow?
What's the best way (paid or free) to research search trends on youtube and Pinterest?
For example if I wanted to find out what the most popular recipes currently are that are being searched for on youtube and Pinterest specifically.
