Getting in touch with people who make similar content is a good way to start. For example, you can read others' content and add value by sharing your thoughts in the comment section. Some of them may check out your content as well. You can do this more to reach more people. At the same, when you make content that is good and useful, it itself draws other people's attention. By the way, there is no easy or shortcut way of doing it, as far as I'm concerned.

Wish you all the best!
