To expand reach, it is important to employ a multi-faceted approach. First, optimize the video titles and descriptions to use keywords that target your desired audience. Creating playlists of related videos can help viewers find additional content they are interested in. Regularly promoting the videos on social media platforms such as Twitter, Facebook, and Instagram can further increase viewership. Leveraging influencers who already have an established audience base is another effective tactic for reaching more people. By partnering with them, their followers may become interested in your channel, giving you access to an entirely new set of potential viewers.
