I just came back from a business trip last night. When I opened QQ, I received some messages from friends, such as why Baidu snapshots are not updated, their rights are demoted, or Baidu does not include them or even reduces their inclusion. Here, I will first answer some people’s questions about why the site was demoted or what caused it to be demoted.
Generally, when the homepage of your site is not on the first page and the index is decreasing, this is an early warning sign of being demoted. Of course, it may be that your content page is of high quality and has a higher weight than the home page, but this situation can basically be ignored. If your site homepage is not on the first page for a period of time, the most likely reason is that it has been demoted. When the index of your site website is 0, it means that you have been K (provided that it has been indexed before).
Then, the reasons for being demoted or K can be summarized as the following four points:
1. The title changes frequently: SE has just understood your direction and content. Just change the title. If you do this often, SE will not know what kind of site you are, let alone the user experience.
2. Major section and structural adjustments.
3. Keyword stacking: serious suspicion of cheating and poor user experience.
4. Keyword density is too high: The importance of keyword density has been repeatedly stated in the previous article. The density needs to be moderate. It is appropriate for new sites not to exceed 4%. For old sites, it is recommended to be about 8%.
5. Words, phrases and related content prohibited by law appear.
6. There is a problem with one of the friendly links, which leads to being implicated: Webmasters need to clean up their friendly links frequently. If they are demoted or Ked due to these reasons, it is not worth it.
Generally speaking, as long as webmasters grasp the above points at a macro level, the chance of being demoted is very small, unless the SE suddenly changes the algorithm, but no one can predict this.
