How to dynamically analyze website construction and optimization from Baidu snapshot?

　　 Situation 1: There is no Baidu snapshot on the website

There is no Baidu snapshot on the website, which is not a good phenomenon. If the website is a new website, it is likely that Baidu has not included the website, so there is no snapshot of the website. If that's the reason, then we don't need to worry anymore. The other is that Baidu used to have snapshots, but now there are no Baidu snapshots in the query. This situation is the worst, because the website is likely to be hacked, that is, dropped by K. The reason for being hacked is likely to be that the website has adopted the "black hat" optimization method, or the website has been maliciously attacked, and the website has been unsafe for a long time, leading to the website being hacked by the search engine. It is also possible that Baidu is updating its data, and occasionally does not have a snapshot. Be sure to notice that the website is blocked by K, correct the inappropriate place of the website as soon as possible, and try to restore the collections and snapshots on Baidu.

　　 Situation 2: Baidu Snapshot has been suspended for a long time and has not been updated

If the Baidu snapshot of the website is stagnant for a long time and does not update, then I think this is not a good phenomenon. Although Baidu snapshot is not updated, it does not mean that the website will be punished, but the snapshot itself is not updated, which reflects the slow growth of website weight and stagnation of website content update. The snapshot date of a website with frequently updated content should be similar to the current date. Therefore, we should also pay attention to the long-term stagnation of website snapshots, regularly update website content, build more external chains, increase the frequency of Baidu's capture, and promote the update of Baidu snapshots.

　　 Scenario 3: Baidu snapshot files are restored to the previous date

Baidu Snapshot has returned files. In addition to Baidu's own data update, the main reason is that the website does have problems. When the website has serious problems, Baidu snapshots will generally be returned. For example, the layout of the home page of the website has been greatly changed, the title of the website has changed, and the space of the website is unstable., This may lead to Baidu snapshots being returned. Baidu snapshot return may also be caused by the penalty of the search engine. When a website is penalized, the date before the snapshot is returned may also occur. For Baidu's response to the snapshot file, we only need to be careful when doing the website, to avoid making large-scale changes to the website, especially the layout and title of the home page.

　　 Situation 4: Baidu snapshot update frequency is not high

This is a normal phenomenon, indicating that the weight of the website is increasing. Because the weight of the website is not too high, it cannot be updated frequently. The snapshot is updated every few days, indicating that Baidu has not punished the website, and is crawling the data on the website as planned.

　　 Situation 5: Baidu snapshot update is too fast

If this happens, congratulations, your website is being trusted by Baidu, and your website is being crawled more frequently, which also reflects that your website weight is increasing and your website content is constantly updated. If you can continue to do so, I believe your website will get better rankings and more traffic.

We can see some clues from these Baidu snapshots. That is, Baidu snapshot can reflect the current status of the website in some cases. These have both good and bad sides. In short, if the website is in a normal state, we can continue to maintain it, or gradually take measures to further improve the website structure and increase optimization efforts. Go up a flight of stairs and you will find the website. For bad situations, we must find out the reasons, correct the wrong practices in time, and get the website snapshot back on track.
