Baidu that no reliable domain command is not Baidu outside the chain

Baidu above the domain command by a lot of people think is "Baidu outside the chain", first not to say, put on two pictures of those who like domain:

　　

This one is domain:www.sina.com.cn, irrelevant www.sina.com appears to have wood there!

To continue to have a greater impact:

　　

This one is site:www.g.cn, but there is a baffling URL there is wood!

Why, Domain is not Baidu outside the chain? Yes, it's actually nothing. Hard to say, and domain:www.sina.com.cn search results most similar to the command is: www sina com cn, basically equal to search these four scattered words. (digression, domain command may be a rotten tail project, because although it did not appear in any of Baidu documents, it is indeed an advanced search command.) But no matter what the data it gets is irrelevant to the chain or whatever.

After the impact began the theme. SEO is a need to explore the unknown field of technology, search engine black box operation rules, we need based on search engine principles, data analysis and other means to slowly grope, but more importantly, is a rigorous logic. This is necessary for the derivation of laws.

So let's take a look at what many people do now, first some irresponsible brick house claiming that domain is outside the chain, and then a large group of people will spread this and serve as the truth-never to doubt its authenticity. Finally, there are some studious seoer appeared, they began to reason: Because Domain is Baidu outside the chain, so you can find that the anchor text outside the chain is not included in the Baidu (domain similar to the direct search URL, of course, not the anchor text link), so there are some people began to doubt the role of anchor text outside the chain.

Seemingly logical, but the fatal mistake is committed in the original premise: domain is not what the chain command. So behind the reasoning, although the study of the spirit is very valuable, unfortunately, because the premise of the error, all the subsequent studies are all deviated from the facts.

But also can not say domain command no reference value (no inconsistencies, to be slowly decomposed), first look at Baidu Webmaster Club Lee said a passage:

The following are the referenced contents: Let's make it clear: is it possible to recognize and process links in plain text form (non <a></a> tags)? The answer is OK, search engine's spider need to discover and crawl the link on the Internet in time, as to the link is what form, not important. Maybe one day we can also identify the links in the picture, in the voice, in the video, or in other forms.

That is to affirm that the text Form link can guide the crawler's crawl, that it has at least part of the reverse link function. And according to their rough statistical analysis, the text form of the reverse chain is also more likely to be able to pass weight.

So the data in the domain also has a certain reference value, because the text form the number of the chain can be from the domain of data from the above show. But this does not mean that we should look at the data in the domain, since it has been clear to their needs, and search command function, there can be a better way.

Initial requirements: Understand the number of links in the text form of the entire site

Search command: Just to find out how many times the network has been the full text form of the chain, then the need for the exact matching of quotes

Final method: Search for "semwatch.org" (quoted)

(Incidentally, such as semwatch.org, such as anchor text URL of the hyperlink will be searched together, this can not be done)

This is a relatively rigorous approach, so that more reference data can be obtained. And because we know the text form the reverse chain is different from the chain form, which should be judged together with the data of the two. Baidu does not provide hyperlinks in the form of a chain of inquiry (text in the form of reverse chain query is also the use of small skills, and unofficial provision), so if you want to get the approximate chain of the form of siteexplorer.search.yahoo.com data or have to rely on such as the use of such tools to make rough judgments.

As for what the use of reverse chain data for a different matter, some people will be used to judge a keyword of the competition, some people will combine into the algorithm to bulk do a lot of keyword competition analysis, in addition to many many kinds of possible uses. The most important thing is not the data, but the people who analyze the data.

Finally, in Semwatch published articles of the audience is very wide, I do not know if there is no one will see the fog spinning, but it can be said, and SERP (search results page) to deal with is qualified seoer daily necessary things. If you deal with it every day, you will know that the text described in the article is only the basis of the foundation. Rather than complaining about the article, it's much better to take some time to settle down and lay the groundwork.
