The day before yesterday wrote an article about the value of friendship links, a lot of friends after reading the reaction in addition to friendship links and one-way link problem, due to the length of the problem today only write about other stations point to the one-way link view of the site.

This one-way link and the difference between links is obvious, is only "into" no "out", so for most people will think that such links for the site itself no harm, or a lot of benefits, but for this view I have some objections, at least not agree.

First or say the benefits, the advantage is to do seo people know, I said there is no meaning, wasting space, over.

Then there is the possibility of adverse effects, for example, also a few days ago, I am in the SEO Untitled station answer group to give a friend to cite example (AD: SEO Untitled station every Friday FAQ group number: 40816143).

The site than a person, the search engine on the site's understanding and scoring mechanism of the part than to do a detective firm or investigation company, outside the chain, is actually someone else's website on your link, we compare it to how many people know you understand you.

Through the investigation, there are several situations: the first one, found that you are famous, the average 10 stars in China have 8 know you, 100 people have 80 know you, 10 national leaders have 5 mentioned you, then OK, you are the authority of the industry you are doing. (Negative content of the site is not included)

The second situation: survey to investigate, only to find that in addition to your family and classmates no one knows you (quality is not a very high link), then you are just a normal person, keep watch.

The third situation: through the survey, found that the average 100 triad of 80 know you, 10 drug trafficking inside there are 5 familiar with you, 10 prison inmates and you have had a relationship, then.

There are many kinds of situation, we do not put forward, only to mention the three more representative, and the comparison of the contents of what that refers to what everyone in mind I do not have much to explain.

The first situation I do not want to say that we can understand, the second situation is also a lot of small and medium-sized webmaster current situation also need not mention, the key is the third situation, that is, some of the misunderstanding of the chain into the situation faced by friends: one-way outside the chain is good! I'm not going to be punished anyway. But you don't think you're going to be punished for looking at the metaphor above me?

A site most of the chain if it comes from some yellow sites, illegal sites, six xx sites, spam sites, then instead of yourself is a search engine, how would you think? Moreover, as Zac said, the core technical staff of each search engine is also a smart person, Ask yourself, myself included, how much smarter or smarter you are than one of them.

For the moment, can already see the search engine for one-way outside the chain's ability to identify more and more strong, Baidu due to the problem of human intervention will be to a large extent directly outside the chain too many of the site to kill, the blood of the lessons to have not mentioned, And Google's relatively gentle performance is not a disregard for the technology user experience, however, Google has not found a fully capable of identifying such sites and at the same time good to kill the site, and once Google found this method or Google changed the gentle attitude, Who can guarantee that Google will not be like Baidu?

Seems to have written a lot, so it, the first SEO Untitled station, www.seo5t.org.cn Lonelywolf, reprint or edit hope to retain the source.
