Answer:
Making yourself look professional.
Step-by-step explanation:
If you're making videos on Yt you want to make sure you're not doing things everyone else is doing and be interesting by being talkative/expressive and seeing what people like to watch, especially the demographic you want attention from. Being consistent and uploading daily will make people stick by longer and see if they enjoy your stuff. An important factor is well presenting the videos/content you're posting through thumbnails/Captions and making sure it correlates with what you're doing.
Hopes this helps!
