I do agree with Bekalu. I have observed various Youtubers and entrepreneurs in the media space where different people have different emphasize on different ways of growing. 

Some emphasize on consistency of uploading content such as the finance Youtuber Graham Stephan

Content related to the current craze and trends like the rise in NFT projects by celebrities such as Jake Paul and Floyd Mayweather. 

While Youtuber Mr Beast would emphasize on the quality content as viewers would appreciate quality content regardless of the amount of upload. 

Do check out this Youtube channel which explores the business side of Youtubers. 

Create lots of content, and focus on newer platforms that are on the rise.

When TikTok was starting to expand globally, those who jumped onboard early got the most engagement for their content. Now jumping on the TikTok bandwagon is probably too late, or may need more effort to grow.

Also, try to make content thats unique and authentically you. There's too much fluff around these days, and authentic content brings a lot more value.

Start by creating good content.

If you can't create good content, just create content. Lots of it.

Be disciplined in creating it all day, evrrrryy day.

Start with TikTok and Instagram, remember to #hashtag your posts, and then move on to YouTube by including keyword-friendly titles + description.

Oh, and find a niche to focus on, not some daily-life nonsense. 

If you like travel, focus on just travel content for a start. Keep it simple. 

From my experience in managing social media pages for companies, I have also noticed that regularly and periodically posting content is important. Moreover, it is important to track when ur followers are the most active and post accordingly. Always keep track of your insights and engagement to see what works and what doesn't. When working with B2C always keep track of the latest trends/ what is going viral and see if it can be used to promote your content. Factors such as editing style, background music etc. should reflect popular content, especially on TikTok.
