Site links and External links analysis

In a Web page, hyperlinks in general text are blue (and, of course, users can set themselves to other colors), with an underscore underneath the text. When you move the mouse pointer over the hyperlink, the mouse pointer becomes the shape of a hand, and when you click with the left mouse button, you can jump directly to the Web page or WWW site that is connected to the hyperlink. If a user has already browsed a hyperlink, the text color of the hyperlink changes. The color will not change until the hyperlink is accessed by the image.

First of all, ask everyone a very simple question, we do http://www.aliyun.com/zixun/aggregation/8495.html "> links for what? Why do links? What are the advantages and disadvantages of doing a link? is the number of external links more than good? Why is it better to be less or more? You feel that if you can answer it comprehensively and persuasively, you don't need to read this post.

Below I give you careful analysis, (the following is purely personal opinion, if there are errors please point out)

1, friendship links are to improve the weight of the site, but also reduce the weight of the site

2, Friendship link relevance is very important, he can determine whether the link is valid

3, the number of links to control good, that is, the number of export links

4, external links to quality is not quantity (so-called quality refers to effective external links)

5, the new station do not do a lot of external links (because the search engine will be judged to be man-made rather than natural causes of the right to fall)

6, the new station do not do a lot of friendship links (reason ditto)

Point out the above point of view, we should all agree, the following I would like to analyze why the above point of view! In my opinion, I should know why he is right so that he can use it for himself. First of all, whether external links or links have a certain degree of effectiveness, that is, the relevance of the site, when the URL points to your station, if the point of the stroke text and the page involved in the content and your station related to the time, then he is effective, otherwise considered invalid, and this void is not useless, But the weight of the home page is relatively small, so there is an external link does not speak quantity but to speak the quality of this argument.

And then is the number of links and select what links good questions, first of all in the selection of links will certainly choose the high weight of the link, this is undeniable, such as PR site snapshots. These I do not speak here, the Earth people know, then I would like to say that there are a few details to pay attention to, as mentioned above the relevance of the problem. Must pay attention to, here I mention a little: for example, QQ space material and QQ Space Code do link, when the QQ space material does not have any regarding the QQ space code information time then these two stations do link only to QQ space valid, but to the material does not have the effect.

So select the link is not the station's data good on the line, there is also a special station, some of the controversial station, such as mm picture Si-fu This category even if the right to high, I do not do, there is a noteworthy problem is: Some people see others station snapshots do not update, included reduced, remove the link, This is very unnecessary.

First of all, his station may be down right. This is true, but there is a problem is based on the search engine update to determine the need for a long time to make the link effective, I can not determine the time, but personally think one months is needed, that is, today you have to do with someone else link, After a few days to find others were down right immediately removed, then in the link this time, did not bring you any benefits but reduced their weight, so the link has to have a long-term, not because a little bit down the right, and delete other people's links, no one can guarantee their station will not be down the right, the algorithm is changing at all times. Then is the link word this is the Miao text, the function I do not say, according to the above reasoning you also know what use!
