First we analyze what is called the station group. The so-called station group refers to the SEO personnel to establish dozens of or hundreds of sites can be crawled by search engines so they can get hundreds of links to promote search rankings.

As you may already know, stations are more likely to attach links to similar sites, such as one-way links, than other types of links, such as two-way links or internal links. You may not believe that search engines can identify each type of link, but they can do it, and have used some of the sites on hand to do some testing over and over again. Discover that search engines constantly change algorithms to detect these stations. Search engines are trying to downgrade these links, so how does he detect that station group:

A similar IP address:

Domain names can vary widely, but their IP addresses may be similar. The IP address consists of a dead area called a region, B region, and so on. such as: The IP address of the website is 58.63.91.83, where a region is the 58,b area is the 63,c area is the 91,d area is 129. And another site's IP is 58.63.91.203, they should have the same IP address, until the C area is the same, the search engine will think that these two stations are placed in the same place and are likely to be related to each other. Links between these sites can be reduced by search engines.

Using the check Domain name IP address tool recommend:

Find a domain name network: http://www.findname.cn

A5 Webmaster Network: http://tool.admin5.com

Ii. similar whois information:

We all know that when you register a domain name, the owner of the domain name provides information about yourself or your company-this information is available to anyone in the WHOIS library. If the domain name that is linked to each other has the same name, phone number or address mailbox in their Whois entry, and so on. Search engines may reduce the value of these links, reducing the weight of the site.

Check the domain name whois information recommended:

Million Net: http://www.net.cn

Find a domain name network: http://www.findname.cn

Third, similar text links:

Search engines also reduce the importance of some links, because the patterns of these links are repeated repeatedly, such as: SEO Service Site got hundreds of links but so the text of the link is exactly the same. These links seem to be organized only for search engine rankings, because naturally occurring links will not be the same text link.

The above is I build the station group to come to some experience, the above several hope constructs the station group's seoer to be careful, certainly the search engine may have other methods to judge the station group's link. However you have a lot of domain names and they are linked to each other serer don't panic. Search engines will downgrade these links, but will not punish your site, which you can rest assured. I believe many friends will have a lot of sites, interested friends can be with me (pidan#gmail.com) to discuss.
