some big companies of different brands of different products, sometimes is not the relationship between each other and also to form an independent website, this time you can.
for small and medium enterprises, the directory is better, because the directory will make the website bigger, sub domain, on the contrary, it will not make the website more and more, only more.
filed a sub domain and directory, there may be a lot of people do not know the difference between them, do not know what should be used when the sub domains, what time directory. Personally, as a Shanghai dragon staff should know clearly what is the sub domain, what is the directory, make the right choice to choose such ability in website construction and optimization of the process, to make their sites do better. The following is a detailed introduction about the difference between the two.
as well as some transnational company in different countries, the sub domain is more appropriate, because these companies are basically by different teams in different countries to the operation of the sub domain and a domain independent of each other, not what difference, but also to establish their own brand.
such as Sina, Sohu large portal, one of its channels are sufficient to separate into a website, because they are a channel content is enough, absolutely more than the web content, this directory is inappropriate, the management is not convenient, a sub domain is more suitable, easy to manage.
don’t know will think of a website is the website of a sub domain domain subordinate, weight will inherit a domain name transfer, the fact is not the case, the search engine will handle the domain name as a new site, and a domain name is completely independent of the weight, not inherited from the level of the domain name. The directory is completely is a part of the site, the weight can be inherited.
sub domain, a web site that the two level domain name. The directory, directory sites, the same classification are placed in a directory. For example, mp3.baidu贵族宝贝 is a sub domain of love in Shanghai, www.baidu贵族宝贝/mp3 is a directory of love of Shanghai, which is two separate sites. (www.baidu贵族宝贝 baidu贵族宝贝 is actually a sub domain, but we generally take www.baidu贵族宝贝 as the main URL, why not, the Convention).
sub domain born higher than directory weight, because search engines regard it as an independent web site, the ranking ability than high directory. That is to say, the same page, if the use is generally better than the sub domain, put in the directory number.
of course, this is only for small and medium-sized enterprises. If a certain type of product you can Dudangyimian enterprise, can make a website alone, or by sub domain from the main website points out.
