Webmaster, seoer, we all know that the site optimization outside the chain is to take up a very heavy weight. Many webmaster, SEO staff will send a large number of outside the chain every day, then how many of them are effective?

Outside the chain: in our website optimization is divided into: links, blog resources and Forum signatures are commonly used methods. One of the links we just do a good job is a valid outside the chain, then the blog resources and the forum signature relative will be troublesome, the trouble is we need to know in these outside the chain which some of the outside chain is effective. Here I want to say a few more, outside the chain is divided into effective outside the chain and invalid outside the chain, then what is the effective outside the chain? In a word, the external chain of Baidu is the effective outside chain.

In the vast number of external chain, especially the forum signature, which outside the chain is included, we can not find in our records to a one in Baidu query is included in it, of course, this method is feasible, query a few of the outside chain is OK, so exactly how simple, accurate inquiries? Please continue to look down.

Site query included, I believe we are very familiar with it, everyone in the mind site is to inquire about the collection of sites. So today I tell you another use of site: site:domain.com+ keyword or site:domain.com+ keyword + user name to query outside the chain, that is, whether it is an effective outside the chain.

Now I on the site of this usage annotation, let not understand a friend to see more clearly some: site:domain.com+ keyword or site:domain.com+ keyword + user name, which domain.com refers to the sent out of the chain of the Web site ( www.domain.com/bbs.domain.com) keywords refer to the key words of the anchor chain; the username is the user name registered in the Web site, where "+" is replaced by a space. In addition, there is no user name difference is: Because in the outgoing chain of the site may have and keyword-related articles, if you do not use the user name query results are included in these articles is not accurate, this situation we need to add the user to query the result is the effective outside the chain we sent.

Site of this use can also be our site rankings and included whether normal, as one side of the analysis. Finally hope that you have read this article for everyone to be afraid of help, I wish you all the dragon, everything Ruyi!
