I have seen your video. Your content is very good. But as it is not SEO friendly, you are not getting targeted views, so subscribers are not increasing. Seen some more issues with your channel recharge. Your videos are not SEO, the title, hashtag, and description are not channel-related SEO, and your channel is not promoted due to lack of proper SEO your videos are not appearing in search results, professional SEO is expected to give good results, and you will benefit. I am waiting for your response.
