Do you make screen-recording videos (eg: gameplay videos, software tutorials) or regular videos? (vlog, tech reviews, etc) Either way, no matter which one you do, quality is the key.
If you make regular videos, make sure you record your content in the highest quality as possible depending on what you're using for recording. Then learn basic camera and scene composition knowledge so you know what you're doing.
And if you make screencast videos, also make sure that the quality is decent, or watchable, which includes everything, from the content, narration, recording quality, and so on.
Audio is also a very important part of a video. Avoid using your camera or laptop's built-in microphone if audio is going to be an important part of your video. Instead, try investing in good microphones that suits your needs.
Then after you've made your video, share them on your social media channels and post them on forums with relevant niche. You can also make a blog post revolving around your video
