Tao Hong’s personal profile: What should I do if the Baidu snapshot for website promotion and optimization updates slowly or does not update at all?

When a search engine enters a web page, it will back up the web page and store it in its own server cache. When a user clicks on the "web page snapshot" link in the search engine, the search engine will display the web page content that the Spider system has captured and saved at that time, which is called a "web page snapshot." The time of the website promotion and optimization web page snapshot should be synchronized with the time when the search engine enters the web page, but in fact the snapshot time seen by the webmaster friends is not the same.

1. Website promotion optimization snapshot is updated slowly

It is normal that snapshot updates are slow. But it can be simply summarized into two situations: 1. The website is not updated; 2. Snapshot updates take time.

1. The website is not updated

The snapshot update time of a website is first and foremost related to the update time of the website itself. If the website is not updated, the search engine spider will not see anything new when crawling, and will naturally turn around and leave, and the backup time in the index library will not be updated.

2. Snapshot updates take time. After the search engine spider crawls the web page, it will first update the time in the index library. The web page snapshot time that users see is the time when it is displayed on the interface. There is a certain delay in the update of search engine snapshots. Not all websites will be reflected in the snapshot immediately after the index library is updated. Therefore, the untimely update of snapshot time is related to the delay in search engine updates.

2. Snapshot time is not updated

The snapshot time is not updated, which can be simply divided into two situations: 1. The website has not been updated for a long time; 2. The website is inaccessible or blocked.

1. The website has been unattended and not updated for a long time. Needless to say, even if the search engine takes care of you, it will not take care of you to the point of being shameless. The time your website was last updated will always be kept, creating the illusion that the snapshot is not updated. Related reading: Scientific website promotion and optimization strategy

2. If the website becomes inaccessible halfway, or the server is shut down, or the spider crawls abnormally due to other reasons, the snapshot update will be abnormal.
