you have good content but i feel your focus needs to be defined. for example, the most viewed videos I see cover 3 different topics: google ads, abm and email marketing. you need to pick one and go deep into it, so people trying to learn that skill know that you will post about them consistently and not keep jumping between topics.
another thing you can try is to experiment with different formats: short form videos, interview, teardowns, case studies, tutorials, hot takes, reaction videos etc. and see which formats work best for your audience. thats the only definitive way to tell what works.
with these 2 approaches alone: defining a focus and finding a format that works, you can 10x your current audience.
then you can do other optimizations like making better thumbnails and/or distribution strategies like cross-posting and collabs.
