you Tube SEO
You Tube SEO if done the right way can increase subscribers & watch hours.
Complete the ground work.
Even before a video is made, thorough search should be done to understand the viewership of similar videos.
Try to understand necessary requirements like performance of various keywords, because Google tries to create competition by pushing more searches to increase their revenue.
Once a channel is made, post videos related to a particular niche or otherwise google algorithms will be confused and will not be able to divert engaging traffic to your channel, thereby leading to high bounce rates.
Once you continue in a selected Niche & you can rest assured things will work out.
Do not focus on Views and subscribers till you have created at least 50 videos.
Avoid shortcuts to achieve monetisation, because it will be caught, because of lack of consistency and consumer behaviour.
