About Baidu to link trading strike algorithm guess

In recent months, the internet most of the webmaster are worried about the thing is that Baidu algorithm updated, and Baidu algorithm update is mainly in order to deal with the low quality of the site and link the sale of links. The author is not a cow, just from the perspective of Baidu, Baidu how to judge the friendship link trading?

One: Buy friendship links.

Baidu Link to the purchase of the site's attack is obvious to all, this period of time, a large number of high weight of the site is down the right, some traffic has been nearly millions IP sites are only the home page ranking K. So how does Baidu judge a site to buy links? The author of this question to do a few guesses:

1, the link source of the website

If the link on your site of the vast number of links is the sale of links to the site, then your site should be to buy links. Here are a few questions: the first question is the vast majority, how many are the majority? This is only Baidu knows. The second question is how does Baidu know which sites to sell links to? We will say later that individuals feel that the judgment factor of buying linked sites and selling linked sites is mutually influential.

2, the weight of the site

About the weight of the site many people will feel that do not understand, because the individual in doing some site optimization, found that some very large sites are also in the purchase of links, but no matter how Baidu's algorithm is updated, the station still did not receive the impact. What is the reason? may be itself this station is a giant, Baidu abnormal trust. It may also be related to the source of our analysis, because such a large station, his links are very rich source, the purchase of some links for the overall link to the proportion of the site is very small.

Two: We talk about selling links

So how does Baidu judge whether a website sells links or not? Judge whether a website sells link personal feel is Baidu this algorithm update of the most important. Because once you have judged which sites are selling links, then it is easy to find the websites that buy the links. So Baidu to determine whether the site to sell links to the method is what? Personally think it may be based on the following points.

1, the site's links to link whether there is a common link between the key words and links platform. Because most of the link platform will require the sale of links to the site to verify the site's attribution problem, and the method of verification is naturally linked to the platform, and verification, many people will not delete this verification link, then Baidu based on this is very easy to find out whether the sale of the link. The second is due to a lot of the site before the link linked to the chain of links directly linked to the link code, and the code features relatively strong, Baidu is very tolerant of analysis. There are many sites linked to the chain of time are listed the same: The above is written on business sponsorship, link platform, and so on these words. Of course, only this is not able to determine whether the site is sold connection, can only say that there is a suspicion of selling links, and the suspicion is enough, Baidu will further analysis, whether the sale of links.

2, the purchase of links to the site there are many of the internet above the prohibited keywords, such as guns, illegal servers, novels and other keywords. Personally feel that Baidu will do a similar feature code such an analysis algorithm, if a site a large number of such prohibited keyword links, then Baidu can say that this site is suspected to sell links.

3, links above the site is the purchase of links to the site. This seems to be a bit contradictory, because the above we said Baidu can be based on the site to sell links to determine whether to buy, and now we say you can buy links to determine whether the site to sell links. In fact, this is not contradictory, but complementary. If your site's outside the chain of most of the links are some suspected sale of the site links, then your affirmation is to buy a link, how to judge whether it is suspected to sell the site, we have analyzed the above points. A large number of websites point to these purchase links, it is easy to determine whether the site is selling links.

4, of course, Baidu may be for each judgment method to do a suspected sale or purchase the link level, when reached a certain level, the site was judged as the sale of links to the site, or to buy links to the site. Some people say that through a site to export links and the proportion of the chain to judge, this person feel very unreliable, because the site's reverse chain is relatively few can not be said to sell the link. For example, someone may like to do a personal blog, rarely optimized, but also like to place their frequently visited sites on the blog links, which led to more export links, and import links are very few, but such a site does not exist to sell links behavior.

Finally, the above analysis is only a small individual conjecture, perhaps my guess and the real situation is very far away, but we can do a reference. Finally, do not always listen to others, rely on their own practice to determine whether a statement is correct.
