Domain basics

Domain image
A domain is simply a "website address on the Internet". For example, in the case of a website with the URL "http: // www. ○ △ × .com", the part "○ △ × .com" corresponds to the domain. No user can reach the website without this address and must be obtained when creating the website.

Domain acquisition is done through a domain registrar called a registrar. One of the most famous ones is "Name.com". The point to note here is that the domains that can be acquired differ depending on the registrar.

That is because, for example, in the domain name "○ △ × .com", you can specify any character string for the "○ △ ×" part,The type of ".com" called the top-level domain is predetermined, and you cannot specify any character string.Because. There are hundreds of types of this top-level domain, but different registrars deal with them.

Domain type

Top-level domains can be used according to purpose, but let's keep in mind that there are two main types.

● gTLD (generic top-level domain)
● ccTLD (Country Code Top Level Domain)

gTLDs are relatively common top-level domains such as ".com" and ".net" and can be acquired by anyone. The other ccTLD is a top-level domain established for each country, and is given the character string ".jp" in Japan and ".us" in the United States. In the case of ccTLD, although there are exceptions in some countries, it is basically a feature that only individuals or groups existing in that country can obtain it. Among the ".jp" in Japan, there are special "attribute type jp domains" such as ".co.jp" that can only be acquired by a joint-stock company or a limited company and "ac.jp" for school corporations. Domains also exist.

Most domain names are in alphabets, but you can also get them in Japanese, such as "Japanese.jp".
We've outlined the types of top-level domains, but they don't have to be specific top-level domains.Basically, there is no big inconvenience in any top-level domain, but if you operate a website in Japan, ".jp" is recommended... ".Jp" is more expensive than domains such as ".com" and ".net". In other words, ".jp" is not so easy to handle. ".Com" is not reliable because it is a hotbed of spam sites due to its low price.

For this reason, ".jp" is safer from the perspective of search engines.
However, just because you get ".jp" does not mean that your website will be displayed at the top of the search results. Still, domain credibility is a non-negligible factor in SEO.

Are Used Domains Advantageous for SEO?

Some domains are called used domains. A used domain, as the name implies, is a domain that someone has used in the past. If the owner who used the domain in the past expires without renewing the contract of the domain for some reason, the domain can be acquired by anyone as a used domain.

This used domain is said to be advantageous in terms of SEO measures.
This is because the evaluation of backlinks from the outside collected by past owners can be taken over as it is. For this reason, second-hand domains are still very popular.

Problems with used domains

But let's think about it here. Even if the backlinks of past owners can be inherited as they are, the external link source website and the anchor text of the link should be related to the website that was operated in the past. Therefore, the inconvenience that the information of the link source and the content of the link destination do not match occurs.

For example, if you try to create a "pizza" mail-order site using a used domain that was operated as a "hair-growth service" website in the past, even though it is a "pizza" mail-order site, it has nothing to do with it. You'll probably find links from websites and anchor texts about no "hair growth services".

Backlinks are important not only in number but also in quality in SEO.Second-hand domains are not always effective because a large number of backlinks that are not related to your site may work negatively.It is.

However, if the website you want to create and the theme of the used domain that was operated in the past are the same, there is a possibility that SEO will have a huge effect, but tens of thousands of used domains are generated every day. On the other hand, there are only a handful of used domains that are really powerful. Furthermore, used domain companies and people all over the world are aiming for such valuable used domains. In that situation, finding and acquiring the desired used domain can be a daunting task.

Precautions when acquiring a domain name

When you get a new domain, you can freely decide the character string. You can use the keyword related to the website you plan to create as the domain name, or if you are a company, you can use the company name as the domain name. However,Only one domain name can exist in the worldYou have to be careful. If it's a domain name that's already used on another website, you can't get it, even if it's the same string as your company's name.

also,In some cases, a domain that should have been newly acquired was actually a used domain that someone used in the past.Some may find this lucky, but be aware that it can actually be very dangerous.

For example, the domain may have been penalized by a search engine in the past and the previous owner just let it go. In such a case, even if you create and operate a website, you may continue to worry that your search ranking will not rise or you will not be able to attract customers without noticing the fact that you are being penalized.
World URL (blacklist check)

To prevent this from happening, be sure to take measures before acquiring a domain. First, check the domain blacklist site such as "World URI (domain) blacklist check (http://www.rbl.jp/checkuri.php)" to see if the domain has violated in the past. is. Also, on the website "WayBack Machine (http://www.archive.org/index.php)", you can find out what kind of website was operated in the past, so you can go back to the history of the domain. You may want to investigate.

Also, avoid using celebrity or brand names as domain names.Domain may be suspended due to trademark issuesBecause.
