Often, to access a website, the URL
includes www. Before the second level domain name (ex: www.prodomaines.com).
This is however not systematic and many sites are accessible without the www
(ex: github.com). Digital marketing services in Lahore have a mission to educate the people.
Reminders about the origin of these
www and their implications, especially in terms of SEO.
What are the www in an internet address?
Technical memorandum on the functioning of domain names
A domain name matches a sequence of
humanly memorable characters with IP addresses, which computers use to
communicate with each other.
A domain name is usually composed
of a top-level domain (the extension: .FR, .COM, .NET, .ORG, etc.) and a
second-level domain (prodomaines in the case of prodomaines.com).
It is possible to add a large
number of subdomains to each domain (up to 127 for the same host, up to 253
ASCII characters). Wikipedia thus uses a third-level domain for each language
(eg fr.wikipedia.org for the French version, en.wikipedia.org for English,
de.wikipedia.org for German, and so on). Each subdomain makes it possible to
create an additional correspondence between a humanly memorable address and an
IP address.
When a domain or subdomain
(regardless of its level) is associated with an IP address, it is called a
host. Hosts are declared in the DNS zone file of a domain name.
On the technical side,
"www" is a subdomain like any other: www.prodomaines.com is a
subdomain of prodomaines.com. However, www.prodomaines.com and prodomaines.com
return to the same IP address when they are polled by the HTTP protocol, that
is to say the one of the web. The site is therefore accessible by both
addresses.
A little history of the web
If many sites work this way, this
has not always been the case. The web (websites accessible by the HTTP
protocol) is not the only use of the internet. Historically, the www subdomain
(for "World Wide Web") was simply assigned to the website associated
with a domain name. Most sites followed this rule (www.domain.com) and were not
accessible by another host, including the second-level domain directly (ex:
domain.com).
Subdomains often indicate the type
of service provided by the host. For example, imap.domain.com and
smtp.domain.com are mail servers, ftp.domain.com will allow FTP connection...
The use of domains without
specifying "www" for the web has spread over time, as has the
practice of entering second-level domains directly into the address bar to
visit a site. There is no longer any "standard" dictating that a
website must be on a host of type www.domain.com.
But suddenly, what shape to choose?
On a technical level, it's the
same: both forms require the same type of configuration. None confers any
particular advantage for SEO.
The choice is to be made according
to the image that the address of the site must bear.
Nowadays, rather corporate or
institutional sites of large organization rather use the form with the www,
probably to clarify that it is about the web site of the company.
Conversely, small structures,
start-ups, intangible services are rather represented by sites whose field is
short, without www, thus working the purified aspect of their communication and
their products. For more useful info Digitalmarketing services in Lahore.
