A friend came to Old Wei and said that the frequency of Baidu crawling on his website was zero, and his operation on the website had not changed. I don't know why Baidu treated him like this this time. Weiaisi Blog is also the first time to see this situation. After thinking about it, we found our way of thinking and started to operate. After a period of time, we finally solved the problem. I believe that this experience is useful for many webmasters who use Baidu's search resource platform
