As others have said by now, the frequency really is nowhere near as important as the content. I haven't been through your content as I'm writing this in my phone but it sounds like you have really short videos, which tells me you've probably don't have enough content. It's important to actually have something to say and plan it out. You can still get the "unplanned" look if you're going for that, but it's still important to have a plan though.
Also another person mentioned editing and it sounded like you don't do it. If your videos are one take videos I really hope you know what you're doing because that is nearly impossible to do right (unless the content calls for it, like unboxings sometimes do). There is a general rule that clips really shouldn't be much longer than 20 seconds before the next cut. It gives more life to the video and it is easier for the audience to keep watching.
Hope you can use any of that
