Domain names can be divided into different levels, including top-level domain names, second-level domain names, etc.
Top-level domains are divided into two telemarketing list categories: one is national top-level domains (nTLDs), such as cn in China, us in the United States, and jp in Japan;
the other is international top-level domains (iTDs), such as .Com for industrial and commercial enterprises, .net for network providers, .org for non-profit organizations, etc.
In order to strengthen domain name management and solve the shortage of domain name resources, on the basis of the original three international gTLDs: (com.net.org), seven new international gTLDs have been added: firm (company), store (sales). Company or enterprise), Web (units highlighting WWW activities), arts (units highlighting cultural and recreational activities), rec (units highlighting recreational and recreational activities), info (units providing information services), nom (persons).
The second-level domain name refers to the domain name under the top-level domain name. Under the international top-level domain name, it refers to the online name of the domain name registrant, such as ibm, yahoo, microsoft, etc.; under the national top-level domain name, it is a symbol representing the category of registered enterprises , such as com, edu, gov, net, etc.
Popularization of domestic domain name common sense
The top-level domain name officially registered and operated in China is CN, which is also the first-level domain name in China.
Under the top-level domain name, my country's second-level domain name is divided into two categories: category domain name and administrative area name. There are 6 category domain names, including ac for scientific research institutions; com for industrial and commercial financial enterprises; edu for educational institutions; gov for government departments; net for Internet information centers and operation centers; org for non-profit organizations.
There are 34 administrative region names, corresponding to the provinces, autonomous regions and municipalities directly under the Central Government. The third-level domain name is composed of letters (A～Z, a～z, uppercase and lowercase, etc.), numbers (0～9) and a connector (-). The length cannot exceed 20 characters.
Overseas promotion should be based on English words. If it is only for ordinary Chinese users in China, you can choose Pinyin to name it. On Baidu, the main Chinese search engine, domain names with pinyin structure are more advantageous.
Use only letters in the domain name
as much as possible without putting underscores, or hyphens. It is only required in one case, that is, when multiple words are combined, there will be two or more word segmentations. Words that are usually linked together, in most cases, can be well distinguished by search engines. One thing to note is that when facing domestic users, Chinese people do not recognize domain names with underscores and horizontal lines in their domain names.
Domain names should be easy to remember. Short domain names with special meanings are more suitable for memorization
. The chosen domain names should not be confusing, and should not be easily misspelled.
The misspelled domain names are likely to log your customers to the opponent's website. For example wine188.com is the same as wine186.com, but it is easy to be confused by visitors.
Beware of registering a domain name that has been penalized by search engines.
Generally, a website is penalized by search engines for violating relevant rules of search engines, and the domain name will be regarded as a penalized domain name.
The penalized domain names may no longer be indexed and included by search engines according to the level of punishment, which means that they will disappear from search engine queries. So, how do we know if a domain name has been penalized by search engines? First, use the SITE command to find out whether the domain name is included, and secondly, you can view the history of the domain name through the http://whois.hichina.com website.
Attachment: How to determine whether a URL has been registered or used?
1. First of all, go to the domain name query center like Wanwang or a place where you can check the status of the domain name to check the registration information of the domain name, whether it has been registered before. If the domain name has been registered, be careful, and then check whether there is a record that has been k.
2. Through (site: domain name), check whether there is a record, and then check the backlink. Using (link: domain name) or (domain: domain name), you can also go to some websites that provide query backlinks or go to your own. Search engines use commands to query, if there is a reverse connection, but the site has no results, then the domain name is likely to be k.
3. The direct input of the URL is recorded, but the site is not recorded, so it may also be passed.
