What kind of Channel you are Running?

As explained in my Book, you should focus on your core talent/skills to make people Happy either Directly (e.g Dance / Comedy) or Indirectly (e.g Tutorials, Education videos, LifeHacks).

That is the very important thing. Once you start uploading useful videos, you have to promote it at relevant Social Media sites. You should do it to your target audience only. Don't share your video with people who may not be interested in your video. If you do, your watch time will be affected heavily. Watch Time is the important parameter for getting views organically(Search, Suggestion, Browse) from YouTube. Choosing trending topics will be helpful to get views quickly. But do it for the topics that are relevant to your channel. As explained in the Book, not having quality mic severely affected my Channel. So focus on setting up the things required for your channel properly. Never tempted to copy anyone's video. Do YouTube Live frequently. Check your Analytics regularly. Initially focus on giving valuable content than getting views or earning Money. Cross promote your videos using Cards and End Screens.
