Common promotion methods include overall promotion, mutual promotion and baidu promotion (CPC, CPS, CPV, CPA). Free website promotion is a new media channel such as forum, SNS, link exchange, B2B platform, blog, Weibo and WeChat. In a narrow sense, the carrier of network promotion is the Internet, and promotion without the Internet is not network promotion. It can be divided into two types: doing a good job in user experience and using Internet platform tools for word-of-mouth promotion.
