Why should seo look at the log, now there is a phenomenon, a lot of seo personnel do not look at the log is doing seo or ** diagnosis, mars summarized that these people are some of the world's masters, this time Walmart SEO ranking declined, and then recovered, it is all the credit of the log, this time I will briefly say why the log is very important for SEO, and the log is also very important for the operator.
Generally, the statistical tools we use are statistical user data, such as GA, 51LA, CNZZ, etc., are statistical users, and the method used is to use js** to obtain, only when such a section of js** will take effect, and the user data will be counted, such as the web page can not be opened, or the page is not loaded into js, or because browsing prohibits running js, then these data are not available, and the data obtained by js we generally have to multiply by the proportion of 5% and 7%.

The above meanings are: visitor's IP date, time, time zone, access method, protocol version, status code, number of bytes, and visitor's system information.
The above meaning will also very well understand the reason why the operation personnel should also read the logs!
