Hi, I have a YouTube channel with 21500 subscribers, I have been getting over 70k views per day, I only uploaded 4 videos, 2 videos got over 1 million views. I think I can help you to rank your videos, but not by specific keywords, to be honest keywords won't help growing your channel.. I understand a lot about how to get ranked on this platform.
First of all you need to get a good audience retention about 50 to 60% watched = How well your video keeps people watching and 5 to 10% impression click through your thumbnail videos.. I can help you with that putting your videos on my end screen, cards and description videos of my channel. It'll help to boost your videos..
Thanks: Juliano
