Recently there is a station PR 3, because there are a few PR5 chain, so PR quickly on 3. But Baidu has not been included. Last night did a part of the modification, this morning issued an updated part of the content, the afternoon site found all have been included, pleasantly surprised, analyzed the next reason. Of course, it's all about self guessing: maybe I used XHTML standards to lay out web pages, to streamline parts of the code, and so on.

The front is all nonsense, sorry! The main thing is to see the page was included in Baidu found a "in order to provide the most relevant results, we omitted some similar items." Strange when I published three pieces of information, the content is very different. After careful examination, it is found that the title of the content omitted not to be displayed has a part where the title of another displayed page is duplicated. This reminds me of the similarity of the Web page, which has not had an exact or crucial solution to the problem. Is it related to the title of the webpage today?

Summarized as follows:

Similar web pages Baidu will not be included or included when not shown in the search results but show as "in order to provide the most relevant results, we omitted some similar items." So in the Content Page title optimization should include only the content page title, do not include the site name, column name or other possible duplicate keywords. This can reduce the wind page similarity, so as to improve the collection of Baidu.
