Domain or a Domain name - is a unique address of a website or part of this address. It is a user-friendly name behind which an IP Address is assigned on which the content files is made publicly or privately made available. These files may contain information, database, images, software, movies or songs etc.
Domains allow users to quickly and easily navigate the internet - you enter a clear and relatively easy to remember able letter or digits behind which an IP-address contains the location of files for that website. In addition, if a site owner to change the hosting, the IP-address of the site change. The Domain Name System allows you to keep the same end address for the user, which retains the branding or marketing juice that was already made. DNS only will know that the physical (IP) address of the site has changed.
DNS is the Domain Name Server, which tells the computer, on any IP-address to search for a website that you have entered into your browser.
The simple and easy chain of communication is as follows:
You enter a domain name in your browser with internet -> it checks your ISP DNS -> DNS grab the according IP-address of the desired site -> site content appears in your browser.
Levels and types of domains
Domains are several levels, counting from right to left:
- com - Top-Level Domain (Also known as TLDs);
- topseokeywords.com - Second-Level Domain;
- analyze.topseokeywords.com - Third-Level Domain.
Domains of the first level
Domains of the first or upper level (TLD - Top-Level Domains) are beginning to address sites. This is just the beginning, not the end of the address - the computer reads the domain name from right to left. Top-level domains are managed by non-profit organization ICANN (Internet Corporation for Assigned Names and Numbers).
Domains of the first level are of two types:
- The national (ccTLD - Country code Top-Level Domains).
Two-letter domains, designated by ICANN for the specific country. For example: .us / .ae / .ru / .pk / .in / .de etc.
There is a standard ISO 3166-1 when creating them which is taken as a basis for country codes. Some national, or as they are called geographic domains used "inappropriately" because of its consonance with English words.
For example, the domain of Federated States of Micronesia .fm very popular among radio stations for registration and domain Tuvalu .tv - among television companies.
- General (gTLD - General Top-level Domain).
General domains have been allocated for specific types of organizations.
- .com - commercial organization,
- .edu - educational,
- .gov - government,
- .org - non-profit.
Initially, the common top-level domains were seven. But with the increasing growth of the Internet was not enough. In 2001, a list of common domains was credited: .info, .biz, .pro and others.
Until recently, private individual or company can register a domain name is the first level, but ICANN has recently lifted this restriction.
Domain zone - a collection of all the domain names the same order belonging to a particular domain. For example, .ae domain zone includes all domain names of the second order, which are included in this zone (dmoz.ae, businessfinder.ae etc.).
Even now citywide domain extensions have also been issued like .nyc (New York City) which has not expanded to the professions/occupational domains like (.club / .laywer / .attorney / .associates / .engineering etc.)
Second-level domains and subdomains
Most sites are located on the second-level domains (topseokeywords.com). Domains third and fourth levels are usually called subdomains. For example, the domain of the third order is as follows: analyze.topseokeywords.com
Subdomains are often used for regional versions of the site or for versions in different languages or having a customized, free or premium services.
It is two or more domain names that are in the same folder on the server. For example, you have domains and fb.com, facebook.com. If they point to the same directory on your hosting, then type the domain name of the user will see the same site. Domains will be aliases of each other.
How to choose a domain name?
Second level domain names can be purchased from registrars - companies authorized by ICANN.
All domain names are unique. You can not register a domain if it already exists. If you want to check whether a free domain name, you can use the service WHOIS. Of course, you can enter the desired name in the address bar of the browser, but not all the registered domain names are actively used, as the site can not be. Perhaps this domain was registered for resale and might be left blank, which is a mistake in terms of SEO. Some people do put Landing Pages just to give a nice experience.
WHOIS - is a protocol that is used to obtain information about the domain. It displays, when and who registered the domain, its IP-address, and contact details of the owner (if the data are not hidden).
If the desired domain name is taken, you can try to buy it or come up with another name.
Some of the domain name searching tools that I use are:
Technical requirements for the creation of a domain name
1) The domain name must be the beginning and the end of a letter or number, and in the middle you can use letters, digits, and hyphens.
2) The length of the domain name has technical limitations. Usually it is not more than 63 characters, some countries to 127.
3) Change the name of an already registered domain is impossible.
Recommendations for choosing a domain name
1. The simplicity and memorability
The shorter the domain name, the better. It is easier to remember a user and when you enter, you can prevent the fewer mistakes. I know my domain name is pretty long but TOP SEO KEYWORDS is rememberable right?
2. Keywords in the domain name
Entering a keyword (the most important in your category) in the domain name increases the relevance of a site for a group of queries that have that keyword.
The most universal format - transliteration, suits and taken into account in the ranking of search engines Google, Bing and Yandex.
Google and Bing understands and takes into account the transfer. Yandex does not understand the translation, except in borrowed words (eg, marketing).
However, if you are too addicted keyword in the domain name, then break recommendation No.1.
3. Level Domain
The site should be at second-level domain, for example, topseokeywords.com.
Domains lower levels (subdomains) can be perceived by the search engines as containing less important information.
Possible domain zone:
- National Country: .us, .ru, .se, .me, .dm, . cy, .pk, .in, .su., .rf etc.
- General: .com, .biz, .pro
- National International: .fm, .tv, .bz
It is worth noting that sites with domain zone .ae or .emirat in Arab Emirates zones have priority at the first site indexing search engine Google.ae. Thus, sites indexed faster unlike sites, which are located in other domains.
After determine the Google.ae site belonging to the Middle East region, indexing site will receive priority standard. This is called local searches. Google has made 201 Localized Google Search Engines till now which helps the users to get the best results near them, rather searching the world. For example if you are looking for DMOZ UAE services in UAE, Google.ae will show dmoz.ae will be shown.
Here is a tip for you.
If you open Google.com in UK it will open Google.co.uk also if you open Google in UAE it will automatically open Google.ae to you.
Now, if you want to set a personalized preference for Google to show you like I want my browser to show me Google.com instead of Google.co.uk to have a global idea of my keywords.
it will set Google.com as your default and not redirect you to local search engine.
