What role does domain play in SEO factors?

 What is a domain?

Domain names, also referred to as domain names and domains for short, are used as a proxy for IP addresses (Internet Protocol), which is convenient for people to remember.
An IP address is composed of a string of unique numbers, used to indicate the location of each computer on the Internet, just like an address or phone number. However, this series of numbers is not easy to remember, and it is not convenient for the dissemination and use of the website.
So DNS (Domain Name System) was developed as a decentralized database that maps domain names and IP addresses to each other. DNS allows people to replace a string of numbers with text names, so they can remember It is much easier to use.
You can think of DNS as the address book of a mobile phone. When you want to make a call, just press the name of the contact person to make the call. You don't have to enter the phone number directly.

The root domain of a website is composed of a top-level domain (TLD) and a secondary domain (SLD). It is the domain used by the entire website. Under the root domain, you can create subdomains with various themes. The level of the domain name gradually decreases from right to left, just like the structure of a folder.
The concept of subdomain is relative. For example, www.example.com is a subdomain of example.com, and example.com is a subdomain of top-level domain.com.

Among the top-level domain names (Top-Level Domains, TLDs)
, there are mainly two types: generic top-level domains (gTLDs) and country code top-level domains (ccTLDs).
Generic top-level domains commonly include .com, .edu, .gov, .info, .biz, .org, .net and other
country code top-level domains, which are mainly composed of ISO-3166 two-letter codes to represent the The country or region where the domain is located, for example: .tw, .jp, .uk, .us, .hk, etc.
 

Second-Level Domain (Second-Level Domain) The second-level
domain name is the second-level structure in the domain and is located to the left of the top-level domain name. The combination of the top-level domain name and the second-level domain name (that is, the root domain) must be purchased and registered from the domain registrar. After registration, it will become a unique website address pronoun. In the example below, those marked in bold are secondary domains:

• www .wikipedia .org
• tw .yahoo .com

Root domain The
root domain usually refers to the combination of a unique subdomain and top-level domain name to represent the entire website address.
The root domain will be the highest-level page in the website structure. Under the root domain, you can create various subdomains or web pages, but technically, the URL corresponding to each page will contain the root domain in it.
Following the example above, the root domain is:

• wikipedia.org
• yahoo.com

Except for using different subdomains as different websites, no two different websites will use the same root domain.
Because of this feature, the root domain can be used to represent the entire website instead of individual pages, so some people regard the number of root domains linked to the website as one of the observation indicators of SEO.
 

Subdomains
Subdomains are in the entire domain structure, domain names below the third level will be added to the left of the root domain in the URL. As mentioned in the top paragraph, the concept of subdomains is relative, so if you add a subdomain on the left, you will add a subdomain to the lower level.
Examples are as follows:

• Subdomain: blog.example.com (third-level domain name: blog)
• Root domain: example.com
   
• Subdomain: www.example.com (third-level domain name: www)
• Root domain: example.com
   
• Subdomain: en.blog.example.com (four-level domain name: en, third-level domain name: blog)
• Upper domain: blog.example.com

 

SEO best practices

(1) Choose an easy-to-remember domain name.
If you want to choose a new domain name today, you should choose a domain name that is short, easy to remember, catchy, and easy to enter as your first choice.
This approach is actually to make the website URL easier to spread, and the things that can be read easily are positively helpful for subsequent memory and use.
 

(2) Do you use keywords in the domain name?
If putting keywords in your domain can help people understand your business, but at the same time make it memorable, unique, and branding, then do it.
But don't do it too deliberately, especially if you put too many keywords in it, it will look "not normal." Although the inclusion of keywords in the domain may be slightly helpful, it is not worth the loss for users or search engines to think that the website provides low-quality content or is not trusted.

When choosing a new registered domain, you may have different strategies. One direction is to use brand-name vocabulary, such as Twitter, which is easy to remember, but may not contain relevant keywords; another possible direction is Use relevant keywords in the domain, such as buyviagraonline.org. There are also some different propositions as to which strategy should be used.

However, those who do not contain keywords in the domain name definitely have a chance to succeed, and most of the time, those names that are familiar and well-known are those that do not contain keywords.

The advantage of including keywords in the domain name is that when reading, users can use it to create associations with the content of the website. However, the problem that may arise is that if there are many different websites that target the same keyword and are placed in the domain, it will be difficult to stand out and make a strong impression.

(3) Use common TLDs
to maximize the flow of directly entering URLs, you should prefer to register the top-level domain of .com. If the name you want to register does not have .com available for registration, you can consider comparing .net, .co, etc. Common ccTLD.
 

(4) Don't care too much about the age of the domain

No search engine has confirmed the use of the length of time a domain has been registered as a rating factor. Don't be obsessed with "older" domains. There is not much difference between a domain registered for six months and a domain registered for one year. The focus is still on the quality of web content and the results of measuring the quality of content through external links. These are the main factors that determine your ranking in search engines.
