The link selection of the resources of the outside chain

&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; In fact, we all know that friendship links are of course the best to do high weights. But what is the high weight of the link. What kind of site is high weight? How should we analyze a site is not high weight? The following points are analyzed.

1. Domain Name

The domain name suffix is inherently weighted, the gov government is larger than the EDU education greater than the Org Bono organization more than com=net=cn= other country domain name, but also has the domain name registration time, as well as constructs the station time. The longer the site is done, the heavier the weight of the site will be. Of course, you can find a link to gov or edu.

2. Server

This is important to see the opening of the site. Whether it is the kind that often appears unable to open or is slow to open. May affect your site at any time.

3. Content

Site content can be divided into original content and relevance content. Especially relevance. Whether and your site link is valuable.

4. Site Collection

A site that contains only one page or several pages. There is no need to make a link.

5. The external chain of the website

The outside of the chain this is also very important to analyze the other site whether there is a black company or buy and sell links, such a site we should stay away.

6. Snapshot update

Quickly whether the next day update or is the most recent, from this point you can see the spider to your site a favorite degree

7. Time included in the article

This can be seen from the article published to the search engine. The shorter the time, the more weight the spider gives to the site.

8. And, of course, PR value.

PR only for Google. Of course, if the other site PR6 above so this site Baidu weight should be not bad. (Of course if you do Baidu so certainly do not see PR.) ）

This is just some of my insights, I hope the old birds to put forward their own ideas to facilitate learning.
