"Snapshot" is a visible "spider trajectory" for many webmasters! So once you have a problem with the snapshot, don't be nervous. Therefore, our siege lion has also found that the feedback on snapshots is particularly high. Mainly around four major points.
Today, the siege lions came out to say, one by one!
First, let's popularize the basic concepts of snapshots for the entry webmasters, such as searching Baidu snapshot screenshots from "Xiangyang Tuoqiang Network", please note the description in the red box:
Basics: Snapshot Generation
The webmaster can understand that the process of generating Baidu snapshots is synchronized with the index update of the web page. At the same time, the index generation will push the content of the latest crawled web page to the snapshot generation program. So it can be said that the speed of indexing the web pages determines the speed of snapshot updates.
1. The layout of the snapshot is disordered, and the page content is incomplete.
The snapshot generation module will display the webpage content to the user through the browser. At present, the snapshot display module can only render the webpage based on static html (in jargon refers to loading through iframe), so for some relative paths of js, css, and images, etc. The material cannot be loaded, or some websites have disabled Baidu domain access to js, css and other files, which will cause typographic errors in the snapshot display and incomplete display of some of the page content. In this case, the webmaster can make corrections according to actual needs.
No web snapshot
For the situation where there is no snapshot information, the webmaster should not be nervous. Here, we just did not generate a snapshot for the webpage, and did not perform some special treatment for the website. 3. Slow update of webpage snapshot content
In addition, the most complained feedback from webmasters is the slow update of snapshots, which involves the frequency of snapshot updates. The update cycle of different web pages is different, and the update frequency of web pages of different websites is also different. Here we can reveal that the longest update cycle is Monthly level, the shortest update cycle is minute level.
4. The webpage is dead chain, but the snapshot still exists
This problem may generally be related to sensitive information. The content has been dead chained, but the snapshot still exists. Here is a reliable method for the majority of webmasters to do the dead chain processing of web pages involving sensitive information, and then perform it on the Baidu snapshot page. "Snapshot of complaint" processing, the specific method can refer to the previous article.
