In the initial construction station, most of the webmaster friends in order to make the child site more professional, easy to remember so select the form of subdomain. For example, the forum, news, and so on, we may be dispersed as a result of the weight of the site, the optimization is more laborious, but let us lose the candle. Talk to you today about the differences and choices between the subdomain and the directory.

Sub-domain name: First, for example: xxx.com is a domain name, also known as the main domain name, and from the first level of domain name extension www.XXX.com, BBS. XXX.com, News. XXX.com and so on are two level domain name, also called xxx.com domain name. We are accustomed to using WWW as the main site domain name, in fact, their level is the same. Need to understand that the first level of domain names and these two-level domain names are independent of each other's website.

Directory: Www.XXX.com/news, Www.XXX.com/bbs and so on is purely a level two domain name www.XXX.com part, also called a site part.

For both of them, I introduce their strengths and weaknesses, sub-domain weight slightly higher, because most of the time the search engine will be the name of a site as a homepage, from the URL point of view, the child domain name than the directory born weight and ranking ability slightly higher, but from the point of view of SEO optimization, I suggest you use the catalogue. Because whether it is a domain name or a level two domain name, they are completely different sites. Usually when we do outside the chain will only do www, that means that there is no relationship with other subdomains, if you want to do several subdomains at the same time, then you must do several times, whether the PR value, or the weight will be several subdomains dispersed, a subdomain after the construction of the chain to get a high weight, Does not represent the other sub domain name to gain the weight, the child domain name will make the website more, each sub domain name will divide the website content to be less, if uses the catalogue, only does the WWW, our website will do the bigger, the content also naturally many, to the SEO is more advantageous.

Remember once I received a network of talent exchange link request, of course, is generally www, a look at this site included only 300, I politely refused him. But he justly said that our collection is mostly in the child domain name job, I see sure enough, the child domain name job included nearly 10,000. This just understand he believes that as long as the main domain name extension of the subdomain belongs to a site, the fact that the opposite. And I and he changed only the site www. We think that he usually do outside the chain is WWW, and the child domain name job is not a little relationship, and most of the content of the site in the child domain name job, SEO optimization in many aspects are only futile.

Of course, this is only the general Web site, in some cases, the choice of sub domain name more appropriate. For example, Web site content enough, such as Sina, Sohu and other portal-level sites. Multinational companies in different countries of the division or branch, take the sub domain name to facilitate the establishment of brands. There are classified information sites and so on.

It is not difficult to see the use of sub-domain name to do the site, are the site large enough content enough, each of the contents of a subdomain is enough to form a site, and visibility has been high enough to promote the funds are strong enough. For our small and medium sites, using a directory is the best choice. Directory regardless of the promotion of the site, PR and the weight of inheritance have a very good effect. To put it simply, to promote a website than to promote two or even a few sites to be easier, we do not only pursue the site's easy to remember and professional, ignoring the site more important weight, content concentration issues, the search engine to make a site bigger and stronger is my ultimate goal. These are some of my sub domain name and directory of some views, I hope to help. Reprint please indicate the original Hohhot talent network http://www.0471la.com/Thank you.
