A lot of time for a novice webmaster just getting started, build a station is must be a technology, after the construction station to use domain name and host, so the domain name and host also need to understand some. Therefore, these basic technologies for a novice in the field of SEO must be mastered, as long as the master of basic knowledge to be competent in the future SEO work.

So, the author why "Domain name level division, as a novice webmaster you really know?" As a title, but also because the author today with a group of three or four years experience in the process of SEO veteran in the course of communication to find a domain name classification problem. For the division of domain name level, it is obvious that the author of this novice does not know much. In their eyes "www.xxxx.cn" is a domain name "xxx.xxxx.cn" is a class two domain name, I do not know you see this article webmaster is also so think.

We should be familiar with the domain name, we visit every day in the major webmaster sites or other types of Web sites, the visit is called the legendary "domain name." Domain name for us to do SEO is very important, the development phase of the domain name is also very interesting, from a network IP began to develop, due to access more trouble also difficult to remember the address, and later developed into a number + letter form. Then, for the novice webmaster say a lot of people know the domain name, but for the division of domain name level you really know? The following are the author and the webmaster to communicate with the author is how to classify the domain name level of understanding.

One: The division of the first level domain name

What is the first-level domain name? I think some of the beginners are still not familiar. Baidu Encyclopedia to give, including the North Jade Bird book on the xxxx.cn belong to the first class domain name. The above also said, with several older SEO veteran chat when talking about www.xxxx.cn belongs to the first level domain name. Why the author here that xxxx.cn is a domain name? In the DNS domain name server, the regular xxxx.cn is a domain name. The first level domain name is also called the top-level domain name and the main domain name of course suffix also includes. com,. NET and other domain names.

For example: the author in the domain name agents registered a domain name, access to the Domain name Control Panel can see a domain name with no relevant domain name and a domain name without aliases. Then this unrelated domain name is the domain name agents of the DNS address specific below will be mentioned. Without the alias is the first level domain name, this time will be bound alias.

Second: two level domain name division

What is the level two domain name? usually to the webmaster, the level two domain name is the domain name under the top-level domain name. A lot of times webmaster will say how I take the WWW is not included without the WWW is included, from this point you can see that the level two domain name belongs to an independent branch, two domain name is included, snapshots, PR value and the chain. Therefore, in doing optimization, the domain name will be made 301来 let the weight and so on all together. For the two-level domain name interpretation, do not take the WWW as a domain name, the other with aliases as a level two domain name.

For example: the author in the author after registering the domain name, the domain Name Service provider is xxxx.cn this time the author will bind this domain name to a WWW, BBS or other alias, After binding, you can use www.xxxx.cn to access the site, and then do the optimization set a good 301 on it.

Third: The division of three-level domain names

What is a level three domain name? In simple terms, the author of the three domain name is interpreted as a two-level domain name below the sub domain name, which is characterized by the domain name contains three ".", in general, this three-class domain name is a free domain name, now there are a lot of free domain names are doing three class free domain Level three domain name can be so displayed: www.xxx.xxxx.cn. So level three domain name is often used in a domain name level.

For example: At present discuz Free forum has one to say so, their domain name: www.xxxx.5d6d.net. If a friend wants to do a level three domain name site can be set up in the Control Panel.

Four: Sub-directory Domain name Division

What is the subdirectory domain name? The subdirectory is a subdirectory of the two-level domain name. Now many do site webmaster will do a number of subdirectories. As is now a part of the classification of information network to do so, the expression is: www.xxxx.cn/xxxx The advantage of doing so is that a domain name can be divided into multiple directories, you can put two of sites into space, and then after the domain name with a different directory to visit.

For example: the author made a website about food, the site is divided into CMS and Discuz forum, want to let two programs at the same time in a host, then, the author can be in the host space to create two subdirectories, and then put different programs. Access can be accessed by a different subdirectory of the domain name.

The above is the author of the knowledge of the domain name division, I do not know whether there is no error, if you do not know the wrong, I would like to talk to you novice webmaster, the division of the domain name must have understanding. So in doing the station will not be the domain name and do not understand the trouble, but also want to chat with me yesterday, those who claimed to have three or four years experience in their own knowledge and my understanding of thinking.
