The site outside the chain is all the key to the operation of the site, so it is often said that the site SEO optimization, three points by the optimization, seven points by the outside chain. In the current domestic, the main judge of the site outside the chain standard has three.

One, Google's link method.

This method is in the Google Web site input such as link:www.***.com format to find the corresponding outside the chain, although this is a very common method, but not entirely by Google official endorsement, they are more recognized through the "Google Web site management tool" to find the corresponding outside the chain. So if you find that through link and management tool search results are biased, it is best to Google management tools prevail.

Second, Baidu's domain method.

Many people think that Baidu's domain method is very inaccurate, why we can go to use to know, outside the chain of data and other search engines have a great deviation, the individual feel that Baidu this way, although not accurate, but also a large extent based on the number of site domain names and not appear on the number of pages to judge. But it can also be used as an auxiliary reference.

Third, Yahoo's link method

This is currently widely accepted as a kind of web site outside the chain to view the way, by my test, respectively, Google and Yahoo search outside the chain, the results of a lot of difference is not big, so Yahoo's approach is also relatively close to Google.

The purpose of the above three methods is not to describe how to search the results of external links in a Web site, but to determine which is more effective. Because a lot of webmaster in the promotion will find, although added a lot of external links, but the effect is not imagined ideal, the reason is that there are many external links and not by search engines that is effective.

So how to judge those who are effective outside the chain of the site?

Personal test to come to the conclusion below, Baidu can give up don't look, if Google and Yahoo outside the chain number up, Baidu nature is not bad. Google and Yahoo can be combined to see, because Yahoo is considered more accurate, but after all, Yahoo's endorsement of the outside chain may not be recognized by Google. Yahoo for the domestic site can almost ignore, so the reference Yahoo results based on the combination of Google Administrator tools to view, this is a more accurate method of the present.
