Since Baidu occupies the dominant position in Chinese search, we often make a series of optimization plans for Baidu. A senior SEOR should understand that the most important friendly links are measured by PR before, whether they are well matched and friendly links. For example, Baidu's snapshot date and keyword ranking determine whether friendly links are exchanged.
However, what puzzles many people is that Baidu’s snapshots often jump inexplicably and do not update. Let me briefly talk about the reasons and solutions for snapshots jumping and not updating;
1. The most common phenomenon of Baidu snapshot jumping is that the snapshot comes out today as the same day, and the snapshot inexplicably reverts to the previous one the next day or a few days later, and this phenomenon often occurs in cycles. According to long-term observations of various websites, this situation is often caused by the originality of the article. Especially for websites with a certain weight, usually after 1-2 months, spiders will often crawl web pages, but updates to the website are temporary, which is what Baidu calls an archive library, and then later In a few days, we will compare whether there are similar articles in this library. Once the spider thinks that there is a problem with the originality of the updated article, it will adjust the inclusion in time, which also forms the phenomenon of snapshot rollback. The solution to this phenomenon is to update original articles as much as possible. Of course, for individual webmasters, it is a bit unrealistic to update original articles every day, so they need to work hard on pseudo-originality. Ordinary synonym substitutions can no longer deceive spiders. , all you have to do is paragraph and splice the article. Splicing different paragraphs from different articles (of course, this will greatly affect readability), but it is also a method for individual webmasters who are weak.
2. The problem of Baidu snapshot not updating. There are many reasons for this problem. Generally speaking, it takes about one month for a new website to go online. The updated content will be quickly included in Baidu and the snapshot will be updated. If it is a new website, you can wait a few more days. At the same time, you should strengthen the construction of external links at this time. Attract spiders to crawl. If it is an old site, it is likely to be punished by Baidu. At this time, there are two steps to check the reason for being punished. The first step is to check the site, including articles, whether it was accidentally published. Articles that lack harmony may be invaded by some unscrupulous elements to create secondary pages on the website, and such secondary pages often contain harmonious content. Secondly, check the links to see if any of your friendly links cannot be opened or are illegal websites. Again, check the website source code. Black links are very rampant now. You can’t see the links they added on the surface, but they are actually hidden in the code. For example, I have a website: www.clarinscn.org . Since the snapshot is not updated, I checked it. It took a long time to find out the reason, but finally I found that someone had put a black link on the website. After removing the black link, the snapshot became normal. These articles and links should be removed promptly. And do a good job in website security protection. The second step is to check the outside of the site. The outside of the site is usually due to excessive optimization of Baidu's own products. This is mainly reflected in the fact that the links in Baidu know are too frequent. Replies on Baidu Tieba are all links, and all types of Tieba have replies and posts. In this way, Baidu can use its own monitoring to find out that these links come from the same person or the same IP, which can easily be considered as a group. The solution is to slowly reduce the number of replies to Baidu Zhiba and Baidu Tieba, and ensure that different IPs are used for operations every day. The snapshot can be restored after a while.
