Does Baidu's keyword ranking take into account historical site factors?

Some of Baidu's algorithms are really weird, so sometimes even Baidu feels incredible.

We usually think that the factors that determine the keyword ranking of a site usually include the quality of the site and external links. In fact, most of the time we perform search engine optimization (SEO) from these two aspects.

However, sometimes we will find that the site has been revised for a long time, and the content of the new site is not closely related to the old site, even saying that all Baidu Index results have been updated; however, the previous keywords will continue to generate traffic, and some unpopular keywords still maintain a good ranking.

When using Baidu for search, many friends may find that some of the results sometimes have no connection with the search keywords-they do not contain keywords or irrelevant content.

 

When Baidu SEO is writing this article, we have tested multiple sites. The test results show that Baidu and Live have this problem, while Google and Yahoo have hardly encountered this problem. (We do not rule out the differences between tests)

There may be two reasons for this situation. Now we will analyze this phenomenon.

Cause 1:

Baidu's algorithms take into account the historical factors of the site, including the historical ranking, keywords, and content fields of the site, and this part of the considerations will be included in the ranking weight calculation of the site in the future, determine the weighted value of the historical content of the new site based on the difference between the adjusted content of the site and the original content. That is, historical factors will be selectively included in the ranking element.

So it will bring us a lot of inspiration when carrying out search engine optimization (SEO). For example, we can buy domain names with good rankings in some related fields, so that we can get twice the result with half the effort.

Cause 2:

Baidu's historical rankings are not updated in a timely manner. This involves Baidu's ranking update mechanism. However, if the indexed results are updated theoretically, the relevant ranking will be updated in a short period of time. However, according to the current situation, the ranking update mechanism seems to be a bit problematic.
