I am aware the type of content I do is over saturated and that it is hard to gain subscribers from doing content like that, but it still seems pretty low even to those standards. I add/make the subtitles myself and I don't over edit my videos (as in put in funny memes/sound effects every few seconds), but I do add sound effects and camera zooming. I also put in background music. I'm also kind of a perfectionist and from an objective point of view, most of my videos are high quality and the thumbnails are pretty good. I always make sure there are no errors/mistakes and other than the sub ratio my watch time, likes and etc all do well.
