Before building content or a site around a niche idea, it helps to check if people are actually interested in it. One way to start is by searching the topic on Google and looking at what kind of content is already out there. If blogs, videos, or forums are talking about it, that’s a good sign. You can also use tools like Google Trends to see if people are still searching for it. Another step is checking if products related to the niche are being promoted by others or sold on popular platforms. If no one is searching or buying in that space, it might be harder to grow. What do you think are some signs a niche is worth building on?
