Baidu Snapshot Description content and the actual Web page description of the reasons for the discrepancy

Morning someone asked run Ming Seo, said the site updated every day, but why the article is included in the title and description of the content and the actual discrepancy? The other is normal, on the Baidu is not the same, I went to open its website a look, do not see do not know, a look startled. So low-level SEO cheating incredibly also asked me why Baidu Crawl label content and the actual discrepancy. Let me show you the picture first.

　　

The first page description in the above diagram is obviously different from the description tag in the image below.

　　

What is this for? December 8, an example of the article said Baidu snapshot did not catch title, description label because the content is not right, but did not catch the reason is said out, but caught but the actual discrepancy between the reason has not been explained, as shown above 2 figure phenomenon.

Here again a Baidu snapshot crawl description and other label content and the same as the actual example (in fact there are many)

　　

The following is a description of the label content

　　

The above 4 diagram clearly illustrates the Baidu snapshot crawl description and other label content and the actual discrepancy is not the real reason for the label content is not correct. What's the reason?

The following diagram shows that the code of the case site in the first picture above is composed of frames, what table, etc.

　　

We know that Baidu on the table frame crawling is not very compatible, and from the principle of the search engine, its crawl system is the first to download the entire Web page, and then the contents of the text extracted, after analysis to remove the HTML format, clear noise, and then participle, and finally deposited into the index library.

Table frame of chaos directly lead to search engine spiders crawl efficiency and results, then take out the rest of the text of the code may be with the actual text error. So this time Baidu for crawling to get the text content and page description label content contrast, if meet, will adopt description label content, if the content of this page, then Baidu will automatically intercept a paragraph of text as the most suitable description of this page. (Baidu is the principle to improve the search user experience)

The following figure

　　

Then look at his description label content "Obviously does not conform to the spider crawl content in the image above."

And Baidu spiders crawl the habit of Web content from the top down, from left to right, and then look at the source code of the author's website are only used DIV+CSS codes layout, and the structure of the site as shown on the home page, also very reasonable

Simulation spider crawl content as shown in the figure (with my description content and the following picture content contrast, obviously see my description content is the most suitable description of the content of the first page, so it shows up)

　　

My description content is:

And from the picture below we can see if your site has no description and content, Baidu automatically to Judge description label display content to display, otherwise ranked out of the page, if the description does not, will inevitably affect the search users in Baidu search experience.

　　

And how is some well-known commercial platform, such as Taobao

　　

But the real title of Taobao is:

　　

As shown in some of the well-known shopping malls, if there are superfluous words, may affect the user's search experience, because there are the words behind, may give the user is posing as a fake station, because we have been accustomed to only "Taobao" three words is the habit of the official website. (Personal understanding, this should be the case)

The last picture of the Taobao case is special, not within the scope of this article.

To sum up, as a general site, only with DIV+CSS code, discard the table frame code, as well as from the top down, from left to right code layout habits to let Baidu crawl normal, to show the actual content with the page to meet the description content.
