TikTok is a system where you have to be tricky. For promotion, I have two accounts, from which I create the first "boost" of likes and comments, so that a new video can get into recommendations faster. In addition, I often use overlays of different sounds: I add the one I want in a third-party editor, and mute the trendy one and use it as a background. But you can get views on tiktok very easily. To do this, you need to try making your first video and you'll understand how it works. Also, don't forget that it's important to be active on other videos. Pick the top 5 bloggers in your niche and subscribe to them. Be active under their videos. Respond to comments to get their subscribers' attention. That way, they can go to your profile and subscribe if they see interesting content.
