Because of the work of the relationship, I have very little time to go to the Forum irrigation, but today the mood is very good to the forum to learn. See a lot of problems, such as how to stop the site, PR will update it, the weight of the site and what the relationship, and a series of Web site optimization problems. In each SEO forum, as if the problem of snapshots mentioned or more, the next knife and you share about Baidu snapshots of personal ideas.

Baidu snapshot in Baidu's Web search Help the introduction is this: If you can not open a search results, or open the speed is particularly slow, what to do? Baidu Snapshot "can help you solve the problem." Every page that is not forbidden to search, in Baidu will automatically generate temporary cache page, called "Baidu Snapshot." When you encounter a temporary site server failure or network traffic jams, you can quickly browse through the page text content through "snapshots." Baidu snapshot will only temporarily cache the text content of the page, so those pictures, music and other non-text information, is still stored in the original page. When the original page has been modified, delete or shield, Baidu search engine will be based on technical arrangements to automatically modify, delete or mask the corresponding snapshot of the page, so the middle of a time lag, if the shorter the difference is that the faster the new update, it means that spiders crawl your page more frequently, But that does not mean that the rankings will be good, as explained in the next article.

According to these, the knife guess Baidu will be ranked all sites, this level only with a snapshot of Baidu relationship, thus based on the level of each site to update the snapshots. Then this level may be divided into several levels:

First Level website: This level of the site Baidu is very important, may also have a certain brand influence, so Baidu has reason to believe that they give the results are more authoritative, then Baidu will be very timely update their snapshots, timely to a perfect state, and even may be the day snapshot ( Today's date is the snapshot date, like Baidu Dictionary, Baidu Bar, Baidu and other related pages will often be the day snapshot, usually snapshots in this level of the site weight is very high.

The second level of the site: Snapshots are divided by Baidu at this stage of the site generally performance of the overnight snapshot, that is, the day the snapshot displayed is the date before. This kind of website is usually updated, and link work is also good, so whenever your page has updated, Baidu will update the next day the site snapshot, such as no updates will not update the site snapshot, so at this stage of the site more.

Third level website; snapshots at this level of the site is usually the periodic update, that is, with Baidu's comprehensive update and update, such as Baidu has been a one-week update, so their snapshots are also one-week update, snapshot of the time is very unified, popular sites are at this stage.

Fourth Grade Website: This level of the site is basically some for a long time is not updated and very few people pay attention to the enterprise station, and the site is not very long time to set up, so this phase of the site snapshots are usually rarely updated, generally in half a month to one months to update a snapshot, or even longer.

The fifth level of the site: basically by Baidu abandoned, if at this stage, the site may be very simple, only a few static pages, made to be purely fun, online after they have not seen.

There may be several levels below, we do not enumerate, I think I do not have a spider so strong thinking algorithm, so I also just based on experience to speculate, then the last level, it must be a number of K or is down the right to be punished by individual special sites, so special treatment. If this is the case, then the site for a long time did not update the snapshot should be from their own site? Try to get their website up to a higher level, there will be a better snapshot, of course, the snapshot does not mean that is ranked, as for the specific situation, The knife will be next: the site snapshot and site rankings have a direct relationship with the article introduced.
