Hello everybody, I am the kiness of Hunan push. Today in the search outside the forum to see a webmaster questions, the content is probably search keyword "Cangzhou women and children" this keyword, in Baidu search results in the title is not the page "descrption" content, but the page in a paragraph of text. But if the search "Cangzhou people" when the display is the site's "description" content, for what? then Hunan SEO small knitting kiness for this webmaster, and also have this question webmaster friends can refer to reference. First, attach the problem diagram.

Figure I (Cangzhou women and children in Baidu search results map):

Figure II (Cangzhou flow of people in Baidu search results map):

You can see from the figure that the snapshot dates from 2012-2-5, today is February 8, 2012. Small knitting here Why to mention the time of the snapshot of the page?

There are generally two reasons for this when the situation arises.

One, search engine crawler crawl the page when the network is not smooth, resulting in web site crawling incomplete. The website opens slowly, the spider crawls the time only to crawl the webpage part content. For example, a lot of time ago in Baidu search results there is no "description", on a title, even the title page is not the current setting of title. Here we look at a snapshot of this page:

Here we can see that the snapshots are complete, so this factor can be ruled out.

Second, the website "description" label does not contain keywords. Let's take a look at the "description" tab of this station.

Figure Small series with bold red line to underline the "Cangzhou Women and children" this keyword, since the description contains the secondary keyword should be in the Baidu search results will show the description, resulting in what is not shown? Here is the small knitting in the previous why to put forward to look at the station's snapshot date. The station snapshot date "2012-2-5", we look at the page of Baidu snapshot of the source code:

From the site's Baidu snapshot source code can be seen in the description does not include "Cangzhou women and children", but contains "Cangzhou", "people" These 2 keywords, the site's description is in the station Baidu Snapshot update after the revision. So in search of "Cangzhou women and children", will be displayed in the Web page with the keyword matching content, and in the search "Cangzhou people" when the direct display is "description" label content. When this station home page was again crawled by Baidu, updated the snapshot, search "Cangzhou women and Children" will show the description tag.
