Reasons for Baidu ranking decline

It turned out to be an external link problem, that is, posts posted on others' forums, which are considered as cheating by the engine because there is only a connection when the content is posted. The article is tedious, but it tells you two mistakes that are easy to optimize the promotion of the two websites. It also summarizes several common problems encountered in the SEO process.

1. Over-Optimized. I repeatedly posted junk posts on other forums a few days ago.

2. Be punished by search engines.

3. The website is attacked by K.

4. The effect cannot be achieved.

5. The ranking is unstable.

6. Website one-sided optimization and SEO short board effect.

7. The server is unstable.

Although downgrading a website by Baidu is not a glorious thing

1. When Baidu's ranking changes, I also started to shop outside the chain. I don't know if I started to shop outside the chain, which led to a decline in Baidu's ranking? Do you have this experience? The website is well ranked, but it immediately drops after the outer link is paved (I leave the outer link regular and will not increase too much in a day ).

2. After the external links are laid, the GG ranking is up, but Baidu's ranking is still unresponsive. In the past, when Baidu ranked the homepage, I went to specialized external links. At most, I sent articles in my blog, and I sent soft texts in admin5, however, even after such a good Baidu ranking (although the GG ranking is not good), I felt that it was necessary to take a two-pronged approach to integrate GG and Baidu, as a result, the ranking of Baidu has declined due to the launching of external links.

3. After the fall of Baidu's ranking, I saw those new pages on the home page. If there were no external links in the external chain, the domain name era was not easy. Baidu did not pay attention to the external chain, what will it look like? Because the quality of new website articles is not high.

4. When I used to rank Baidu stably, for example, liposuction. This keyword used to rank very stably, but the external link on this page has never been done before. It is still on the Baidu homepage. Now the link is made, but the ranking is declining (my website is a 2000 domain name, will it be because of the long history of old domain names that there will be good rankings without external links ?)
