[Communication] Baidu's new algorithm for recording and clearing operations since June

This is a new algorithm that my engineer who worked in Baidu told me that Baidu has recorded the zeroth action since June. The following content is only the main method, the specific detailed algorithm is based on the following content. I cannot obtain the specific algorithm because it is Baidu confidential.
1. baidu has imposed severe penalties on sales links and exported more than 40 links (some well-known sites are not affected). Links exported from factories, garbage stations, and sites within half a year have no weight. For all irrelevant links, there is about a tenth of the associated links.
2. Baidu has added the recognition of hidden links, and hidden links have no weight.
3. baidu has cracked down on the purchase of GVM, educational institutions, and public institution links. Baidu has built GVM, educational institutions, and public institution databases to rank specialized keywords for such websites, the exported links of these websites are invalid.
4. All outer chains exported by Baidu products have no weight to combat the behavior of optimizing Baidu products.
5. baidu does not give weight to all links exported from websites selling links on the platform. Baidu has built a feature library for the platform, such as a verified website in chinaz, websites that are verified by Alibaba, websites that are automatically linked by Alibaba, and Baidu systems can be automatically monitored. after discovering that these websites will be added to the database of websites that sell links, links exported from websites in this database are useless.
6. Baidu recognizes Forum posts and reply users, it is regarded by the system as spam and spam reply (Baidu builds a feature Library Based on the top-up principle of some automatic top-up hosts and some universal replies (that is, common replies, if this feature is met, it will be considered as spam content.) No weight is given, and non-original (the recognition principle is the same as that of the original article) replies, posts or replies with the same content repeatedly published by the same user are not weighted.
7. Baidu will make more efforts to view overseas space and unfiled websites.
8. Baidu has enhanced the pseudo-original Checking Algorithm Based on the pseudo-original methods of common collection software, such as section disruption, keywords replacement, and part truncation. Baidu can now detect this, baidu will solve the proportion of the website's pseudo-original content and junk content (I don't know the specific amount) and will remove all the pseudo-original content.
9. Baidu has a limit on the quantity of collected content to be included (not specific, but it is not affected by the large site). After the number is reached, it will not be included.
10. baidu has not exported links, but many websites with imported links are added to databases suspected of purchasing links for key monitoring and manual troubleshooting, monitor and troubleshoot databases that are added to the imported link of the website to a suspected sold link.
10. Baidu reduced the influence of the outer chain on the keyword ranking of the website, but it was unknown.
11. Baidu gave high weight to long-time original websites.
12. the weight shared by Baidu is greatly reduced (it is very likely that it is not directly lost). Baidu does not have an effective solution because there are too many shares shared by Baidu, so the weight shared by Baidu is greatly reduced, however, when Baidu has a good anti-cheating method, Baidu shares a high weight.
13. Only give high weight to high-quality blog posts
PS: high quality criteria: words, originality, non-spam content, and comments (same user comments are now recognized by Baidu ).
14. No weight is given except for the export link of high-quality blog posts.
15. Baidu can recognize meaningless content generated by stacked characters and words. Baidu will regard the content as junk content and punish it.
16. Some methods for sending outer chain on well-known websites have expired (such as using bookmarks)
17. Baidu regards the outer chain behavior that does not give weight as cheating. Baidu will add these outer chains to the database of suspected cheating websites for key monitoring and manual troubleshooting.
