On my channel the videos I post are typically 5 minutes long. After we reach 100 subscribers I’ll look into having 8 minutes videos. Once we reach 500 subscribers 10 minutes videos. 1000 subscribers I will have 15+min videos
Let me tell you that consistently really is key. I started back uploading 3x a week and just this week alone (being my first week) I’ve gained 3 subscribers. This is a long journey and the little wins build up over time
