Lol that’s not how you get subscribers, my brother makes a living off of YouTube and im sure that sharing a link for subscribers or sharing a video link is the worst way to get subscribers. If you want actual subs then make better content. your videos should tell a story that shows progression. And to keep views and click through rate high should be your goal, because subscribers are not what’s going to make your channel popular. And begging like this wont help you succeed.
And dont post at a certain amount of subs that will not help your channel. Your videos should be on a schedule like every week or month to keep content coming. One thing that helps is also learning from your most popular video to see what made it popular and how you could improve.
Just kidding, not gonna advertise YouTube channels either!
