Brief comment on cookies

Experienced SEO experts often use cookie and sessionID to reasonably guide and control spider crawling and Baidu weight transfer. In order to better balance the user experience and spider crawling, we can optimize the navigation structure of two sets of websites. One set is used to show Baidu spiders, and the other set is used to show users, which is conducive to improving the search experience of target users.

When you try to attract target users to get traffic by using micro-headlines and short content, many websites often pop up registration and login pages. When you register successfully, you will still go back to the same website to continue reading the original content.

When we try to get the target users through email marketing, we often need to count the opening rate of each email, so as to adjust the content strategy of the email. At this time, we use cookie to track the target user's visit to your website, so as to judge the user's visit to open the mail.
