There is no guaranteed way to get 1 million subscribers on a YouTube channel, as the process can vary greatly depending on the content, audience, and marketing strategy of the channel. However, some general tips to increase your chances of growing your audience on YouTube include:
Creating high-quality and engaging content that is relevant to your target audience.
Consistently uploading new content on a regular schedule.
Optimizing your videos for search by using relevant keywords in your video titles, descriptions, and tags.
Building a strong brand and image for your channel through a consistent visual aesthetic and tone of voice.
Promoting your channel and videos on social media and other platforms to drive traffic to your channel.
Collaborating with other popular YouTubers in your niche to reach new audiences.
Interacting with your audience through comments, social media, and other means to build a community around your channel.
Constantly analyzing your analytics to understand what kind of content resonates with your audience and adapt accordingly.
Be patient and consistent. Growing a large audience takes time and effort, but with persistence and dedication, it is possible to achieve.
Keep in mind that YouTube's algorithm rewards regularly posting and engaging with your audience. Also, YouTube's policies on clickbait, misleading titles, and other manipulative practices are strict, so avoid those.
