First do good Keyword research(Focus on low competitive SEO keywords). Check the videos that rank there and see how many backlinks they have, the quality of the links. If you can beat the videos that are ranking on top by giving it enough quality backlinks, then you are good to go. make sure you also optimize all the video elements including the urls, etc

Where can I take high quality backlinks?
I know you can find many tutorials how to do it but most of them are old or not working now.
How many backlinks daily to be safe?
I gave a video 5k verified backlinks yesterday, it's now 4th on google. That was the easiest ranking I've ever done.
