Site staff in SEO optimization, query external links There are roughly three ways: first, through a number of Webmaster Tools query, the second is through Baidu or Google search queries, three are through software statistics. At present, webmaster tools and outside the chain of query software used by the majority is still Baidu and Google two search engine link or domain command, from the search results to see how to find the true number of external links to the site.

Method One: Searching the chain directly with search leads

Advantages and disadvantages: Baidu and Google two search engine link or domain command, from the search results can understand the search for your identity, like some we do a lot of outside the chain, in Baidu Search, on behalf of some of your outside the chain Baidu has not included, or do not agree. These practices can be considered to stop certain outside chains.

How to: Query site External links we usually use link and domain two commands.

Note: Sometimes we find that these two commands are not the same as the actual search results, and note that link and domain in different search engines represent different meanings.

First: Link:

Baidu,link does not represent an instruction, just an ordinary keyword. Link:www.xxx.com search results are all pages that contain such a key word group, and as with other common keyword searches, do not find backlinks.

Google, looking for a reverse link, but only contains a small part of all the backlinks of the site. We recommend using Google Webmaster tools to check all backlinks in the site.

Yahoo, looking for a reverse link, but need to add "http://" in front of the domain name, such as: link:http://www.xxx.com (domain name plus and without "www" result is not the same).

Second: domain:

Baidu, check the content of the page contains a keyword. For example: Domain:www.xxx.com search results are all pages that contain key word groups. Domain can be useful if you want to find out how many Web pages contain your URLs.

Google,domain does not represent an instruction. Just an ordinary keyword.

Method two, Sogou rank query

Advantages and Disadvantages: Query outside the chain command or more accurate, the link accuracy rate is basically more than 85% (not excluding a small number of sub-domain names within the chain), but also in the query results in the query to get the rank of Sogou.

Methods of operation: In the search dog search outside the chain method is: Open Sogou home page, in the Searching box input link:www.xxx.com, you can get a return to the site's external chain results.

Note: Sogou rank value is similar to Google PR value of the site (page) rating index, the score from 0-100 reflects the quality of a site and the number of external links. Unlike Google, its statistical reference does not need to install Google Toolbar, a certain level, the external chain of investigation, than Google PR more objective, here can give examples: if the same site, its Google PR value is 1, and Sogou rank is 41, you can say, The rank value of the Sogou accurately reflects the external link index of your site.

Method Three, Yahoo Webmaster tool query

Pros and Cons: The function is pretty good, search results are more complete than the other two methods, basically you publish all the results of the chain. But included update slow, tried search results one months ago the other side has deleted the chain to the www.lx43.com chain. These outer chains have been invalidated in Baidu.

How to: Yahoo Webmaster URL is http://sitemap.cn.yahoo.com. In the search bar, input http://www.xxx.com, the first to get the site is Yahoo included results page, click the "link to the address of the page" button, they got all the links to the National Education Web site search results.

Note: You can see that there are many internal links, there is no relationship, select "Filter the current domain name under the link" option, you can get more pure outside the chain results.

Summary: Outside the chain (external link) has become the impact of a larger site weight of one of the factors, query the site outside the chain, is basically the habit of each site staff action. But it is recommended to search the chain at the same time combined with the above three methods to get more accurate results. At the same time to do outside the chain should be careful not to do in some search engine punishment of the station to do, lest the joint punishment.
