Analyzing different snapshots of different keywords from the technical point of view

Different key keywords different snapshots of the phenomenon appeared for a long time, before there is speculation that Baidu server problem, so long past, the phenomenon still exists, such a guess naturally untenable.

Come up with such a topic, inevitably some blush, I do not know much about search engine technology, just read a Zac "network marketing actual password", the search engine principle only general understanding. I'm going to look at this from a programmer's point of view and share some of my thoughts and guesses with you.

1, for the home page, there will be multiple Baidu snapshots, multiple snapshots of the role of similar to the backup of the site.

This, I believe that do seo people can understand. Every time Baidu big update, there will be some of the Web site's snapshot back to the file, how to return to the file? Typically back to the previous Baidu snapshots backup, and this backup, most of the last time Baidu big update for the backup. For example, this time after the update of Baidu back to the phenomenon is more obvious. A lot of snapshots back to the November 9, 10th and 11th, and the most recent Baidu update skillfully starting from November 9, 10th full update, 11th end, because the snapshot back to the 10th site particularly many.

2, for the home page, Snapshot archive will have multiple, but generally only release 2 snapshots.

There are multiple snapshot archives, on the one hand, multiple backups are both convenient and secure (from the procedural point of view), on the other hand, some of the site snapshot back to the previous several times before the big update Baidu, to prove this point.

Generally released 2 snapshot time, is observed, may have released multiple snapshots of the situation, but have not seen. The following picture shows a certain degree of this view.

3, for the home page, different keywords different snapshots of the key is the keyword in different snapshots of the weight is different.

　　

　　

Above this site a lot of people should be familiar with SEO. You can see 2 snapshots, keywords egg pain nets for the next day snapshot, the key words Wuhan SEO for the last big update snapshot number 10th.

Through webmaster tools to observe all the ranked keyword snapshots (home), only 2 time, November 10 and November 22. To some extent, it proves the conjecture in point 2.

To Wuhan SEO this keyword Observation 2 snapshots, found: 10th of the snapshot page appeared in Wuhan 8 times, SEO19 times, and the 22nd snapshot page appears the keywords Wuhan 7 times, SEO18 Day, (because the keyword density is different) so the search for Wuhan SEO is 10th snapshot, instead of 22nd snapshots. It could be a coincidence, but it's close to my guess which snapshot of the same keyword is all around and the weight of the keyword on the different snapshots. If this is true, then another guess is that Baidu Snapshot archive not only the net also text snapshots, including the weight of the site.

Summary: The above 3 points are for the homepage of the site, the view is through observation and guess, although for speculation, but I think persuasion is still relatively strong, have a good reference role, hope for everyone useful.
