Why does the snapshot time of each keyword in the website be different

Perhaps webmaster and seoer in the attention of Baidu snapshot should find a very strange problem, also often encountered problems, that is, we search the site's keywords, will appear, search for different keywords and search out the snapshot time may be not the same, some are new snapshots, some are old, Why does it have such a phenomenon? (for example, this site today at the same time to check the two keywords Changde seo and changde site optimization of the snapshot times are not the same, one is November 1, one is November 7, the latter is yesterday) in general, because of Baidu different server update time is not uniform cause ( However, Changde SEO personal understanding may also be the weight of this keyword is not how to do. Careful analysis, not only the problem of snapshots, in fact, can be extended to the following three questions:

1, why Baidu will have different servers

A: Baidu will capture a lot of data every day, each snapshot page a few k to a few 10K, resulting in its hard drive infinite amplification, to a certain extent will be added to the hard disk, add to a certain degree will be added to the server, that is, the old data constantly increase, do not change the server will be very slow.

2, why different keyword snapshots are not the same

A: In order to make the search faster, faster, Baidu side of the same keyword data on the same server, in order to achieve the fastest search results. Because the server updates snapshots at different times, it can cause a difference in the snapshot time between servers.

Can be simply understood as "changde seo" keyword database placed in a server, "Changde website optimization" Of the keywords database stored in B server, a server update, B's server has not been updated. So lead you to search the keyword "changde seo", is today's snapshot, search "Changde website optimization", is the previous snapshot.

3, the above statement should be a lot of home snapshots, why I site: Web site will only appear a snapshot of the home page, and is the latest?

A: Site is the senior internal command of Baidu Search, once the correct site command, Baidu Search program will call all the data stored in the site, through comparative analysis, discard the same page, take the station all the latest snapshot of the record page, so the site after a snapshot, is always the latest, and is the only.

It is because of site, Baidu needs to query, call all records of the site server information, so that caused our site to display the number of pages is not accurate, usually we point to the last page of the record, and will appear, we click again, is the correct all the capture data. (Changde seo Friendship tip: In order to provide the most relevant results, we omitted a number of similar items, click here to see all the search results).

In general, the site each keyword snapshot time is not the same as the site itself, as long as their own site no zuobi, you webmaster and seoer can rest assured that this is only the update delay Baidu server! My friends can spit trough can be praised, hope everyone a lot of exchanges, a lot of guidance, Changde SEO will be able to accept humbly!
