Decryption of Baidu's website indexing and clearing rules

I saw a post posted by a web friend on the internet asking Baidu to set search indexing rules. In fact, Baidu has already developed a website building guide named Baidu and webmaster, and published How to make websites indexed by Baidu, what kind of website will Baidu refuse to include or discard related terms. In my article "Baidu anti-cheating means lose credibility", I mentioned that these terms are too general and can be interpreted and misinterpreted by them in practice, without practical operation significance. Then, in this article, Stone will analyze the related terms of Baidu's refusal to include and punish websites, so that more people can understand Baidu's relevant rules.
The full text of Baidu-related rules can be found in "Baidu and webmaster". After careful reading, we can conclude that the reasons for a website being denied or punished by Baidu are as follows (note: the corresponding analysis is added after each entry ):
1. Keywords irrelevant to the body are accumulated in the title.
The echo between the title and the website content is emphasized. If a keyword is involved in the title and the actual website content is irrelevant to the keyword, it may be deleted by Baidu. this clause reflects Baidu's strictness. however, it is worth thinking about how Baidu judges the relevance between the website content and the title keyword? Does the title contain a keyword ??? If not, can Baidu's current search technology be analyzed in terms of meaning and logic like humans? For example, can the machine determine whether acrylic in the title of the partition is the same as the organic glass mentioned in the text? Of course, if Baidu uses manual review sites, this article will be very good and operational! However, there is another problem. The manual review is irrelevant. Which of the following statements prevails?
2. The automatically redirected page may be discarded by Baidu.
This article does not require many comments and mainly targets cheating activities. Most search engines have similar clauses.
3. Do not have too many links on the same page. On those website map pages, give links to important content instead of all details. Too many links may also lead to failure to be indexed by Baidu.
How many connections are considered too many ?? It is recommended that there be no more than 100 Google users. What about Baidu? Baidu can use this item to punish most of the large websites. Most of the large websites have dozens or even hundreds of connections on their home pages.
4. If your site has been optimized for Baidu, but it has brought a lot of negative experience to users, your site may eventually be left cold by Baidu.
What is too much optimization for Baidu? Is there a detailed standard? Although the meaning of this sentence is very good, it seems that anyone with a conscience should be applauded, but the key question is what the specific operating standards are? No one has a different opinion on over-optimization and negative thinking. For example, I think the first page of Baidu search results is advertisement, which affects my feelings. Should I delete it?
