SEO Case Study: Manipulate Baidu snapshot let the snapshot heart and change

According to FGYB these days of observation, found an interesting phenomenon, that is, Baidu Snapshot reference page inside the "Time" factor. See figure below

　　

This article was published on June 17, 2012, but why does the snapshot show time as "2011-4-1" and why does this anomaly occur?

This is a bold guess, that this phenomenon is because the information is said last year, the text of the article has "April 1, 2011", because the text appeared in the "Time" factor, and then affected the Baidu snapshot, resulting in snapshots show time is also "2011-4-1."

To verify my thoughts. June 18 and released a few articles, included in the following figure (can site test site: www.sqr8.com View details)

　　

Sure enough, the snapshot time into "2012-2-23", and the actual release of this article is June 18, 2012, is obviously the text of the "February 23" time factor caused the Baidu snapshot through the strange phenomenon.

I came to a conclusion: Baidu snapshot time will refer to the article in the "Time" factor, notice is only a reference, not absolute, because in this test also found another phenomenon, that when the article appeared in different "time" factors, Baidu will give up the reference article in the "Time" factor.

For example, in this test article, there is an article in the body of the text there are two pieces of content

November 11, Xinhua insurance to the Taiwan debris flow in the death of Beijing female leader of the family claims more than 50,000 yuan.

November 5, Xinhua Insurance Beijing Branch received a report, Customer field in the November 3 to Taiwan to visit the mountain debris flow died. ”

The following picture is the Baidu snapshot of the article, we can see that although the article appeared in the "Time" factor (November 11, November 5) But the snapshot is still 2012-6-18, this phenomenon is due to the article appeared in different "time" factors, resulting in Baidu can not make accurate judgments.

　　

To sum up the manipulation of Baidu snapshot time: That is, in the article, a complete "time" factor, and the article can only have a "time" factor, meet these two conditions can let the snapshot time in accordance with their own will to display.
