Snapshot and snapshot update mechanism in Baidu search engine 

1, what is Baidu snapshot?

What if I can't open a search result, or if it's very slow to open? " Baidu Snapshot "can help you solve the problem." Each of the included pages, Baidu has a plain text backup, called "Baidu Snapshot." Baidu is faster, and you can quickly browse through the content of the page with a snapshot. However, Baidu only retains the text content, so, those pictures, music and other non-textual information, snapshot page or directly from the original page call. If you are unable to connect to the original page, non-textual content, such as pictures on the snapshot, cannot be displayed. So, for some closed or inaccessible sites, if you want to see some of the content can be achieved through the Baidu snapshot Oh.

All along, some owners of Baidu snapshot update time there are some misunderstandings, that the site's snapshot update time and the weight of the site has a certain relationship, the more frequent snapshot updates, the higher the weight of the site, conversely, the lower.

In fact, there is no direct relationship between the update frequency and the weight of the site snapshot.

2. Why is Baidu snapshot updated?

First, it is necessary to clarify that the crawl frequency of a webpage and the update frequency of a snapshot are two completely different concepts.

Every Baidu is included in the site, Baiduspider will be based on the frequency of its website content update constantly check whether there is a new page generation, usually, the Baiduspider crawl frequency and the site to produce new content speed, usually said the update, Refers to Baiduspider crawl of Web content. This is not the same time as when you update the site content.

Each new crawl or newly checked pages, Baidu side will be based on its importance and its timeliness value at different speeds to create an index, usually said snapshot update time refers to the index time, some often have important content updated pages, we will be faster to create indexes. If a Web page is just a general text change or the value of the content is not time-sensitive, and will not necessarily be the search engine think there is a fast update index value, even if Baidu spider re-crawl the page content, its snapshot will not necessarily be updated quickly, but this does not mean that it is not important or Baidu update speed is very slow. So, it is necessary to keep the website original and some quality content is high.

3. Why is snapshot time backwards?

Snapshots of an important web page tend to hold multiple snapshots of a Web page in the search engine database, and the snapshots are not captured at the same time. In some very special cases, the search engine system may choose a snapshot version that is different from the current search results, resulting in a reverse snapshot time. This does not have any influence on the website in the search engine performance, also does not represent the search engine to the website to do the lower right processing.

In summary, the update of the snapshot is directly related to whether there is any important new content in the page, and it is not directly related to the "weight" or "K" of the website itself. Business owners do not have to pay much attention to the site's snapshot time, it is recommended that business owners focus on the content of the site building, only improve the content value of the site and the search experience, can be trusted by users and search engines.
