Site URL standardization determines the preferred domain centralized weight to prevent the right to be lowered.

What is the preferred domain: the domain that you want the search engine to use to index your pages (sometimes referred to as canonical domains) is the preferred domain name for your site.

Popular say the preferred domain is the site's preferred domain name.

I often see that there are many webmasters who have been complaining in the forum, two questions

1. Why my site does not add WWW rankings, and add www no rankings, and the previous site all the outside chain is

Hyperlinks to the WWW domain name. Without the addition of WWW, there is no hair outside the chain.

2. Why site: domain name. com's collection of the amount of site:www. And it also exists.

Site: domain name. com and site:www. com's included many articles are the same.

Figure A site: domain name. com

Figure II site:www. domain name. com

The contents of the first page of Figure two are the same.

The crux of the matter: 1. In fact, add the WWW domain name is a class two domain name, and no plus www is a domain name, the weight of a domain name

Natural than the two-level domain name to high, in the domestic custom to use the domain name plus www.

2. Why there are no rankings of WWW, but there is no plus www rankings

I personally in the process of SEO, also encountered this situation, and most of the webmaster, like all the outside chain, all the trace text is pointing to add WWW domain name

And our site's program, no URL standardization (that is, our website program, binding any one domain name, can be normal access).

For example: 1. Barcelona encountered Aravis (this is an article on my website) in the history of the King's Cup 4 times (this is the relative value of this article)/zuqiupk/2012103114.html

When my website binds two domain names, is domain name respectively. com. www. domain name. com. two domain name, I can pass: domain name, com/zuqiupk/2012103114.html, www. Domain name, com/zuqiupk/2012103114.html. Can be normal access: Barcelona in the history of the King's Cup a total of 4 encounter Aravis this article. This is the Barcelona in the King's Cup history of a total of 4 encounters Aravis article, I have two ways to access. So when the search engine crawls our site,

Hou will also have the above mentioned two methods can be accessed, then the weight of the site in the search engine will be divided into 2. And the search engine would think that. Domain name. com/zuqiupk/2012103114.html, www. Domain name, com/zuqiupk/2012103114.html. This article is a repetition of the article.

Your site will have a lot of the same article, will be the search engine down the right. In order to make the weight of the site more concentrated, more higher to produce a preferred domain this term.

2. When we optimize this article in Barcelona in the history of the King's Cup a total of 4 encounters Aravis (www. Domain name. com/zuqiupk/2012103114.html) This article, we encounter Aravis for the description of text, through other sites, self-built blog, as well as well-known blogs, There are other sites to point to this article (hyperlink for http://www. Domain name. com/zuqiupk/2012103114.html), because this article also has many ways of access, so the weight of this article can not be centralized, so the weight may be 1/2 weight.

How to implement: URL normalization determines the preferred domain

1. We are accustomed to add www for the preferred domain name, will not add WWW domain name 301 to add www domain name.

2. The path of the first article is to use absolute address, such as the first page of the Chinese webmaster Net article is to use Add WWW address, such an article corresponds to a URL.

Summary: 1. URL normalization determines the preferred domain first to centralize weights. 2. URL standardization to determine the preferred domain this can effectively solve the similarity of the article, to prevent the right to be lowered.
