Hypertext Transfer Protocol (HTTP) and World Wide Web (WWW) are two acronyms widely used online. As you’re probably aware, both concepts have an impact on your day-to-day browsing activities, as they’re an inherent part of all website URLs. However, this knowledge base is not well understood by the vast majority of internet users.

HTTP and WWW were initiated in the late 1980s by Sir Tim Berners-Lee, a British computer scientist. His project – the World Wide Web – involved HTTP and WWW working alongside one another, playing crucial roles in the incredible system we take for granted today.

In this post, we’ll discuss what a website URL is, and we’ll explain the differences between HTTP and WWW. We’ll also highlight how each is used in a URL and their importance in website domain names. Let’s get started!

HTTP vs. WWW

As mentioned briefly above, HTTP is the standard ‘language’ used to communicate between web browsers and website servers.

WWW stands for World Wide Web, and it’s used mostly as a prefix. However, it does indicate that a given website uses HTTP to communicate.

The main difference between WWW and HTTP is that they refer to different concepts. Simply put, HTTP is the protocol that enables communication online, transferring data from one machine to another. WWW is the set of linked hypertext documents that can be viewed on a web browser (such as Google Chrome, Firefox, and more).

A major similarity, though, is that both HTTP and WWW are used in website URLs.

HTTP vs. WWW in URLs

Within the URL parameters, it’s possible to remove HTTP or WWW from your domain registrar. However, the situations in which you would remove one of these elements depends on a few factors.

As we stated above, WWW is a prefix used to indicate that a website is using HTTP to communicate. In fact, you can mix and match prefixes, for example http://example.com or www.example.com.

These different URLs have enough information to communicate between the browser and server, so both will work without any interruptions.

So, what if you do choose to use http://example.com as your website URL, but users type in WWW where it isn’t necessary? In the majority of cases, the user will be automatically redirected to your non-WWW domain. This means you can set up a non-WWW URL address without worry.

Do You Need WWW in URLs?

It’s actually not necessary to use WWW in URLs. It exists for just one purpose—to identify the web address. This is not the case with other important URL signifiers, such as a File Transfer Protocol (FTP) server (ftp) or news server (news). As such, WWW may be classified as a subdomain of a larger website.

In most cases, WWW serves no technical purpose. You can create a custom domain without its presence, and the website will still operate as any website should.

So, why is WWW used so frequently? The use of WWW has been around since the creation of the internet, and its widespread use as a subdomain was largely accidental.

The first web server was nxoc01.cern.ch. When publishing the website, the creators fully intended for info.cern.ch to be their home page, and WWW, as such, was excluded. The Domain Name System (DNS) records for the server were never switched, and the use of WWW became an unintentional standard practice.

As mentioned, it is possible to create a custom domain name without WWW included. Though, there are some considerations to keep in mind.

Domain or Web Address without WWW

In the majority of cases, a user will not have to type WWW to view your web address or domain. However, if you’ve implemented WWW to differentiate between subdomains, it’s important to ensure that your site is configured to provide the appropriate redirects to users.

For some websites, the addition of the WWW in www.example.com may cause a redirect to example.com. For others, it may be two separate pages on the same domain. Your web hosting provider should be able to help you set up to ensure the correct redirects are in place.

WWW and non-WWW for SEO

If you run a website, Search Engine Optimization (SEO) should be a high priority. By having a good SEO strategy in place, you can better ensure your site will rank highly on Search Engine Results Pages (SERPs), and drive more traffic as a result.

Ultimately, whether you use a WWW or non-WWW domain name has no bearing on your SEO. What does matter, however, is that you choose to stick with one or the other (and not mix both elements).

For SEO purposes, you want to use one URL (either WWW or non-WWW) consistently throughout the website. This means all URLs attached to your domain should have the same designation.

Doing this will ensure your website rankings aren’t split across two different domains (e.g. www.example.com and example.com) but rather applied to your canonical domain only.

 A complete List of domain suffixes and their definitions.

.com = Commercial site. The information provided by commercial interests is generally going to shed a positive light on the product it promotes. While this information might not necessarily be false, you might be getting only part of the picture. Remember, there's a monetary incentive behind every commercial site in providing you with information, whether it is for good public relations or to sell you a product outright. (See the Information, Disinformation, Misinformation page)

.edu = Educational institution. Sites using this domain name are schools ranging from kindergarten to higher education. If you take a look at your school's URL you'll notice that it ends with the domain .edu. Information from sites within this domain must be examined very carefully. If it is from a department or research center at an educational institution, it can generally be taken as credible. However, students' personal Web sites are not usually monitored by the school even though they are on the school's server and use the .edu domain.

.gov = Government. If you come across a site with this domain, then you're viewing a federal government site. All branches of the United States federal government use this domain. Information such as Census statistics, Congressional hearings, and Supreme Court rulings would be included in sites with this domain. The information is considered to be from a credible source.

.org = Traditionally a non-profit organization. Organizations such as the American Red Cross or PBS (Public Broadcasting System) use this domain suffix. Generally, the information in these types of sites is credible and unbiased, but there are examples of organizations that strongly advocate specific points of view over others, such as the National Right to Life Committee and Planned Parenthood. You want to give this domain scrutiny. Some commercial interests might be the ultimate sponsors of a site with this suffix. (See the Information, Disinformation, Misinformation page)

.mil = Military. This domain suffix is used by the various branches of the Armed Forces of the United States.

.net = Network. You might find any kind of site under this domain suffix. It acts as a catch-all for sites that don't fit into any of the preceding domain suffixes. Information from these sites should be given careful scrutiny.

The contact information provided by an <address> element's contents can take whatever form is appropriate for the context, and may include any type of contact information that is needed, such as a physical address, URL, email address, phone number, social media handle, geographic coordinates, and so forth. The <address> element should include the name of the person, people, or organization to which the contact information refers.

<address> can be used in a variety of contexts, such as providing a business's contact information in the page header, or indicating the author of an article by including an <address> element within the <article>.
