Lift the subdomain and directory, there may be many people do not know the difference between them, do not know when to use the subdomain, when the directory. Personally, as a SEO personnel, should be clear about what is a subdomain, what is a directory, so that in the site construction and optimization process needs to choose when to make the right choice, so that their own site to do the better. Here is a detailed description of the difference between the two.

A subdomain, a two-level domain name for a Web site. Directory, that is, the classification of the site, generally the same category of products placed in a directory. For example, Mp3.baidu.com is a subdomain of Baidu, Www.baidu.com/mp3 is a directory of Baidu, this is two independent website. (Www.baidu.com is actually baidu.com a subdomain, but we generally will www.baidu.com as the main URL, no why, the conventional).

Do not know may think that a website's sub domain name is this site level domain name subordinate, will inherit a domain name passed over the weight, the fact is not so, the search engine will be treated as a new site domain name, and a domain name is completely independent, will not inherit from the first level of the weight of the domain name. The directory is completely part of the Web site and can inherit weights.

Sub-domain names are inherently higher than the directory weight, because the search engine as a stand-alone site, its ranking ability is higher than the directory. In other words, the same Web page, if the use of sub domain name, generally better than placed in the directory ranking better.

For small and medium-sized enterprises, the use of a directory better, because the directory will make the site more and more, the sub domain name is the opposite, it will not make the site more and more, will only do more.

Of course, this is only for small and medium enterprises. If you are a certain type of product can be Dudangyimian, can do a single site, or with a subdomain from the main site from the good.

For example: such as Sina, Sohu, such a large portal site, any one of its channels is enough to be a single site, because they have a channel under a lot of content, absolutely more than the general content of the site, this time with the directory is not appropriate, management is not convenient, with the sub domain name more appropriate, easy to manage.

There are also like some multinational companies in different countries, the use of sub domain name is also more appropriate, because these branches are basically from different countries of different teams to operate, subdomain and a domain name independent of each other, no difference, but also easy to establish their own brand.

Some big companies of different brands of different products, sometimes the relationship between each other is not large enough to become a stand-alone website, this time you can choose to do with a subdomain.

Like 58 with the city, net and other such classified information site, but also with a subdomain to do, different cities with different subdomains. These classified information sites have a large amount of data per day and are more geographically strong, and each province, or even every city, is a single website.

It should be noted that the subdomain and the main site are two separate sites, the main website needs to be promoted, the sub domain name also needs, the child domain name does not inherit the main website the weight, also will not be affected by the main website rank, will not because the main website rank good oneself also to rank well, because they are two different websites.

In addition to the above, there are other references to the choice between the subdomain and the directory. For example, if we use the Google search engine, the above situation does not need to consider, because for Google, the site's home page, the table of contents and the status of the page is the same, to give the same ranking opportunities. If Baidu, then the sub domain name than the directory more conducive to ranking.
