Experience on troubleshooting Baidu snapshot Rollback

It has been more than half a year since the 442 live broadcast went live. The website's PR value has increased from 0 to 5, which is a great encouragement for me.

After the website is launched, Baidu snapshots have been running normally and are generated the next day. However, in August 3, it was found that the snapshot of 442 live broadcast suddenly returned to July 28. Because the previous snapshots were too normal, I was worried about the snapshot rollback.

Since the problem arises, the first thing to do is to identify the cause and solve the problem. I don't know much about SEO, but I often visit the webmaster's website to read related articles, learn the experiences shared by everyone, and have a very abstract understanding of SEO theory.

Based on your past experience, to solve the snapshot rollback problem, first start with the link. After checking the links, I found that several websites have recently been indexed by Baidu K to varying degrees. Some websites have seen a sharp drop in the number of indexed items, and some have lost their home page snapshots. To save snapshots, I can only remove these links first. I would like to describe the situation on the website after removing the link. I believe that the stack can still be understood, in this way, at least we can ensure that our cooperation will continue after both websites resume normal operation.

Several days after the link is removed, the website snapshot remains unchanged on January 1, July 28. After eliminating the issue of friendship links, I also asked some webmasters who analyzed that it may be because I stopped developing external links during this time. It is true that this period of time, due to work reasons, has not made external links for the website. In order to restore the website snapshot to normal as soon as possible, I can only spare time to do external links. After a few days, the website remains unchanged, which can cause me to be anxious.

My other website has encountered the problem that the installation of hardware protection on the server affects the crawling of spider and affects the indexing of Baidu, this time I also considered whether the server where the 442 live broadcast is located has also installed hardware protection. After asking the customer service of the host service provider, the customer service said that the website's server was not installed with hardware protection, and this reason was also ruled out.

Finally, only dead horses can be used as active horse doctors. I modified the title, keyword, and description of the home page of the website, hoping to attract the attention of Baidu Spider to record the home page. One day later, when I visited the homepage again, the tragedy happened in expectation. There were still home page snapshots in July 28, but this home page snapshot was gone. After finding this result, I immediately changed the homepage title, keyword, and description.

It is not the reason for the link, or the reason for the external link. What causes snapshot rollback? Because of the program used by 442 live broadcasting, we have already shared it with two friends. One of the websites using the same program was launched in August 2. This detail is worth noting because several websites with the same program are easily considered as image websites, which are not very friendly to search engine spider. What's even worse is that when the website with the same program was launched, it made a friendly link to each other, which makes it easier for the search engine spider to judge the two websites as mirror websites.

This is the last reason I can think. I discussed it with my friend and asked him to shut down the website of the same program for a few days to see if it was the reason for the image. After one day, the site still does not have the home page snapshot. Two days later, the website snapshot has completely recovered to normal, and then returned to the 24-hour snapshot, which is also ranked first on the site result homepage.
