1) A second-level domain name is a domain name that is hosted under the primary domain name.

2) The second-level domain name belongs to an independent branch, and it has its own index, snapshot, PR value, backlink, etc.

3) When the primary domain is penalized, the second-level domain name is also penalized.

How to set the second-level domain name: 1. Log in to Wanwang, find "My Domain Name", click on it, and there is a resolution behind the domain name. Turn on and stare at it.

2. Click "Add Resolution" to officially start adding the second-level domain name. 3. If the second-level domain name points to a resolution server, select CNAME as the record type. If it is a **, select implicit URL or explicit URL, the difference is that the address in the address bar changes or does not change after the transfer.

If you do not want to display the actual address, it is recommended to use implicit. Here, since I'm pointing to a resolution server, I'm using the cname record. 4. The host record is your second-level domain name.

For example, if you want to set the second-level domain name to ", then fill in the host record"sy\"。5. The record value refers to the address to be turned, that is, the actual address. 6. After the stool is set up, if it is transferred to a **, then it is over.

When we carry out domain name resolution and construction, we often have three concepts: first-level domain name, second-level domain name bright and simple sale, and second-level directory, so what is the difference between first-level domain name, second-level domain name and second-level directory?

1. The number of levels of domain names is to see how many are behind the domain name"."A delimited suffix.

For example: "fuyeor com" has a to:"."The delimited suffix is a first-level domain name. where com is the top-level domain, or root domain name, domain extension.

The second-level domain name is the domain name hosted under the main domain name, which is the domain name one level to the left of the naked domain name. Generally speaking, second-level domain names are comic formats like 3 ws (www).

For example: "www fuyeor com" has two toes"."The delimited suffix is a second-level domain name.

For example: "docs fuyeor com" has two toes"."The delimited suffix is also a second-level domain name.

There is also a secondary directory, that is, a subdirectory, inherited from the main directory, which is equivalent to creating a folder under the root directory of **. For example: "www fuyeor com zh-cn" means that there is a folder of "zh-cn" under the root directory of **, which is a secondary directory.

From the perspective of optimization, usually the weight of the main domain name is the highest, the second-level domain name is second, and the second-level directory is lower than the second-level domain name.
