From the SEO point of view, a site multiple domain name practices, in the optimization after the promotion is extremely unfavorable, will undoubtedly increase a lot of difficulty in optimization. Because two or more domain names, search engines take for granted will know to do two different sites, and a site of two domain names are also indexed by search engines, it goes without saying that in the eyes of the "spider" It saw two of the same site. Do SEO people know, then this represents what.
The following must be a primary and secondary distinction for these two domains. Check the next two domain name outside the chain, and then through the collection, snapshot date and other factors to see the current search engine has been more valued which domain name, and thus the primary domain name. However, this time Baidu and Google valued domain name may not be the same, the most difficult to do is the choice of Baidu and Google site domain name is not the same domain name, we must discard one, but also pay attention to observe these two domain names which domain name on the ranking has a natural advantage. And also will encounter some special circumstances, such as Mister named to use which domain name and so on. However, regardless of the situation, first the main domain name set out.
After choosing a good weight, the domain name to be discarded is forwarded to the main domain name. Now to do is to let the search engine to rename one of the domain name, while the domain name gradually discarded. First of all, it must be with the main domain name to add a few high weight outside the chain. Suggest spending some money or through relationships, buy a few high weight outside the chain, and continue to update every day, increase the appropriate outside the chain, under normal circumstances, for some ordinary sites, expected half a month time, the main domain name will get a good weight.
If it is a complex chain of sites, there may be some problems, such as titile display is not normal, or more than half a month, the domain name does not make much progress, this needs to be optimized for the specific situation.
