Most sites use a domain name, but some sites use two or more domains for a variety of reasons, such as Sina used Sina.com and Sina.com.cn, just enter sina.com will jump directly to Sina.com.cn, a site if the use of more than two domain names, if handled improperly, it may bring adverse impact on the site. I've had a loss for this reason myself lately.

In order to test the use of Baidu know to do long tail keyword ranking effect, I decided to use a separate domain name to Baidu to know the above to send some long tail keyword questions and answers. At that time there is no certainty, fear did not achieve the effect is the main domain name Baidu penalty, I used another site of the two domain name resolution to the main domain name space, and in the space behind the binding of this level two domain name, so I this site has two different domain names.

Because I this advertising media forum has been done for three months, Baidu also included dozens of pages. I think Baidu will be my primary domain name as the first weight of the domain name, the new binding two-level domain name will be judged as a vice domain name does not give any weight, so then there is no heart, also did not do 301 redirection settings. Binding this two-level domain name, I use this level two domain name to Baidu know to send a more than 10 long tail keyword questions and answers and take this two-level domain name link, one weeks after these questions and answers have been ranked Baidu search the first three places. But I can't imagine the problem.

Two weeks later, I found that my main domain name is not included more and less, snapshot update is not previously new, at that time was not thought to be the new binding of the two-class domain name caused by the exclusion of other factors, I went to the Baidu site of the two domain name included in the number, do not check do not know, a check startled, My new binding of this two-level domain contains more than 400 pages, and the main domain only included more than 60 pages (into the map), it is obvious that Baidu has now put my new binding of this two-class domain name as the main domain name given a high weight, and the main domain name as a deputy domain name, so the number of secondary domain name is now more than the main domain name.

After I analyzed, may be I this two-level domain name in Baidu know the top more than 10 caused by the chain, Baidu know the weight of the chain is relatively high, so I this two-level domain name outside the chain weight of the main domain name outside the chain weight, Baidu also put me this level two domain name as the main domain name, and the main domain name as a vice domain name treatment. In order not to affect the weight of my main domain name, I yesterday has lifted this two-level domain name binding, of course, this two-level domain name in Baidu know that the chain is also white hair. This is a lesson for me!

After me this thing, I have come to an experience, is a website best use only one domain name, really do not have to use two or more domain names, that must first do 301 redirect, the Deputy domain name permanent Redirect to the main domain name above, so that Baidu will not produce a miscalculation, will not affect the weight of the main domain name.
