Belonging to the external window of the media, it can plant grass or bring goods for brands and advertisers according to its own fan base and strong fan stickiness. KOL is the latest marketing method of new media, which gives full play to its advantages in coverage and influence. KOL fans are very sticky, especially in terms of values, so fans recommended by KOL will watch them carefully.

KOL is still different from what people usually call online celebrities. Simply put, KOL is an account with appeal, influence and considerable credibility in its field. This account can be a real three-dimensional celebrity, a two-dimensional image, or even a hobby. There are three criteria for judging:

1, circle expertise.

2. Stable and insightful content.

3. Interest or talent.
