After posting your vlog, you may get some feedback from viewers. While not all feedback is useful (or actionable), pay attention if you notice a common theme among the feedback; this demonstrates that enough of the people who saw your vlog felt the same way that you should consider using their feedback in future vlogs. For example, if a few people mention that the music was too loud or obtrusive, try lowering the volume of music in future vlogs. You can keep the same general formula for your vlog, but make sure you aren't simply copying your steps from the previous vlog. For example, if your last vlog involved going to a coffee shop in the afternoon and then visiting food carts, try to avoid both of these activities in the next few vlogs. Once you've created a few vlogs, you'll probably begin to see a trend taking shape. At this point, it's good to determine what that trend is and figure out how to continue it in future vlogs. This will ensure that the people who view your content know what to expect when you upload something, and you'll have a general framework for your content going forward. As with any form of expression, your vlogs will likely change over time. Knowing your general theme will help make this transition more gradual than if you're uploading without knowing what the overarching theme is. Once you have a few vlogs uploaded to your platform of choice, begin talking about them on other forms of social media (e.g., Facebook and Twitter). This is a good way to grow your vlogs' collective audience.  An easy way to do this is by creating a Facebook page for your vlogs and then posting links to the vlogs there. You might even want to notify a few close friends whenever you post; if they enjoy your content, they may share it with their friends as well.

TL;DR in Chinese:
试着将观众反馈融合进以后的视频。 每次都制作不同的视频。 确定一个主题。 推广你的视频。
