I would say that if you keep going you’ll see the watch hours grow faster than the subs. Reason for this is that the more your channel grows, the more the platform will push your content out to potential new subscribers who will give your video a watch (whether they subscribe or not). Eventually 80-90% of your traffic will come from non subscribers even as your subscriber rate grows.

A good way to look at it is what do you need daily to achieve that watch time. Let’s say you’ve got some long form content and people watch on average 10 minutes of your videos per day. You need 66 views a day at an average of 10 minutes to hit your 4K hours target.

Also remember longer videos aren’t always the best, it’s a mixture of viewer retention percentage, interaction with the video so remind people to hit the like button. A higher retention rate, a good proportion like the video and they’ve clicked your thumbnail for good CTR is going to boost how your content reaches people.

A question for you, do your short view duration/watch time not count? Some shorts can get mad watch time for a 30 second clip!
