I looked for a lot of information on the Internet, read a lot of people wrote about the URL does not calculate the chain of the article, some people say that the URL is not a hyperlink is also a chain bar, but the effect is not good with links. This answer is a point of view that I agree with. Some people say that the URL is not a hyperlink to the chain, Baidu only as a text included, no point of use. Some said Baidu did not develop a look at Baidu outside the chain of tools, Yahoo has a special search outside the chain of tools, so the Yahoo will prevail. I have been very disagree with this view, because I do the station Baidu outside the chain without hyperlinks accounted for my site outside the chain of 3 2, ranked very well. Yahoo's chain is few and far between. I did an experiment myself for this problem.
First of all, I made two websites, the content of the website, the template, everything is exactly the same. The key words to do is Shanghai Carton Factory, Shanghai moving Carton, description are the same, Shanghai Carton Factory The word competition is not small, Google's search results are 3.4 million. In the same day to submit Baidu, Baidu is also included on the same day both sites. Baidu included two sites, updated to the 10th page. I took a name for two websites, in order to distinguish, one is a station, one is B station, a station is to do Baidu outside the chain, that is, the URL does not add hyperlinks outside the chain. B Station is the chain of Gasu links. Key words Shanghai Carton Factory A station is the 4th place on the 10th page, B station row in 10 pages 6th, did one months experiment, the result came out. 8 days later, the first update of two sites, Shanghai Carton factory a station than B station ranked High 6, that is, the 9th page. Another 10 days, the website updated for the 2nd time, Shanghai Carton factory a station ranked 6th, while the B station in the 8th page, the difference is very big. Another 12 days, Shanghai Carton factory a station ranked on the 2nd page, and the B station ranked far behind. On the 5th page, one months time, a station of Baidu check the chain around 830, of which there are 20 linked to the outside chain, the new station is like this. NetEase Forum has the outside chain, the people's network, 58 with the city, net and so on. B Station Yahoo check the chain around 870, of which there is a link to the outside of the chain, Friendship link PR value is 3. There are a lot of miscellaneous 7 chaotic 8 outside the chain, there is a soft text of the chain, Sina BBS outside the chain, there are signatures and so on.
Now I have come to the conclusion that the Web site is not a hyperlink outside the chain is useful, but also useful. And I have always been the view that the Web site is not linked with a hyperlink outside the chain or useful. I hope the novice do not mistakenly into the "Web site without hyperlinks outside the chain is no use" erroneous view.
