When promoting and optimizing the website of Shangrao, the snapshot will not be updated and the snapshot will be reversed. So what causes these phenomena to occur? Let's first understand what a snapshot is.
Snapshot is the search engine crawls the content of the website and stores it in the form of text on the server. In the case that the visitor cannot open a search result or the opening speed is particularly slow, the visitor is provided with the text of the website content previously saved. Then, when our website is stagnant and retrogressive, we can analyze the reasons from the website's server, website content, and website external links.
Website server The impact of the website server on the website is great. When the server fails and search engine spiders can't crawl the website content normally, it may cause snapshots to stagnate or even go backwards. If a site in the same server is downgraded by a search engine, it will also affect the entire server's site.
In the process of website optimization, the existence of external links is a catalyst to promote website keyword ranking. When the external chain fluctuates greatly in a certain period of time, such as a large increase or decrease in a short period of time, it will cause the vigilance of search engines. And a large number of spammy external links are also the cause of abnormal website performance.
Since the snapshot is the text that the search engine crawls the content of the website and saved on the server, the content update and content quality of the website are related to the update of the website snapshot. If the content of a website is mostly collection content, or the website cannot maintain a certain frequency to update the website, then the website is very bad in the search engine evaluation, and the snapshot naturally cannot be updated.
