First; First of all, your video should be original, aiming at the field, aiming at the product and aiming at your video quality.
Second; Your video should be focused, concise, and not too long (if it is too long, not many people will have the confidence to continue watching it, which will affect your user experience). For example, the headline video of our weekly diary 520 is usually about 5 minutes.
Third; The copy of your video should be clear, uncomplicated, not titled, not exaggerated, and around the theme of your video.
Fourth; Learn more about peers, learn from them, and fill the gap with your own imperfections.
Fifth; Related data analysis, one way is not enough, try another way, in short, write more and you will realize the truth.
The above is purely a personal opinion. Please forgive me if there is any mistake. I hope I can help you. ....
