If you've never built a website before, it can be difficult to understand what actually happens when someone types a web address into their browser and a website appears on their screen.
A website might look simple from the outside, but several different things work together behind the scenes.
At the most basic level, a website needs a domain name, somewhere to store the website, and the files, content and technology that make the website work.
This guide explains how those parts fit together in simple terms.
What Is a Website?
A website is a collection of pages and other digital content that is stored on a computer connected to the internet.
The pages can contain:
- Text
- Images
- Videos
- Forms
- Links
- Products
- Menus
- Other interactive features
When someone visits your website, their web browser requests this information and displays it on their screen.
The website itself is stored on a server, which is a computer designed to store and deliver information over the internet.
What Is a Domain Name?
A domain name is the web address people use to find your website.
For example:
example.co.nz
Instead of remembering a complicated numerical address for the server where your website is stored, visitors can use a domain name.
Common domain extensions include:
- .co.nz
- .nz
- .com
- .org
- .net
A domain name is essentially the address people use to reach your website.
You need to register a domain name before you can use it for your website.
What Is Website Hosting?
Website hosting is the service that provides space for your website on a server.
When someone visits your website, their browser needs to retrieve your website's files and information from somewhere.
That's where hosting comes in.
The hosting server stores the information required to display your website and makes it available when someone visits your domain.
Think of it this way:
Domain = your website's address
Hosting = where your website lives
How Does a Website Load?
When someone enters your domain name into a browser, several things happen.
1. The Visitor Enters Your Domain
Someone types your website address into their browser or clicks a link to your website.
2. The Browser Finds Your Server
The domain name is connected to the server where your website is hosted.
The browser uses this information to find where it needs to request the website.
3. The Website Sends Information to the Browser
The server sends the information required to display the requested page.
This can include the page structure, text, images and other resources.
4. The Browser Displays the Page
The browser processes the information and turns it into the webpage you see on your screen.
This all happens very quickly.
What Is a Web Browser?
A web browser is the software you use to access websites.
Common browsers include:
- Google Chrome
- Microsoft Edge
- Safari
- Firefox
When you visit a website, the browser retrieves the website's information and displays it for you.
The browser is essentially the tool that allows you to interact with websites on the internet.
How Do Websites Get Built?
There are several ways to build a website.
A website can be created using code such as HTML, CSS and JavaScript, or it can be built using a website builder that provides tools for creating and managing the website without requiring you to write the code yourself.
With a website builder, many of the technical elements are handled for you.
You can generally:
- Choose a website design
- Add pages
- Add text and images
- Create navigation
- Add forms and other features
- Edit your content
- Manage your website
This is one reason website builders have become a popular option for small businesses and people creating their own websites.
What Happens When You Click a Link?
Links connect pages and websites together.
When you click a link, your browser requests the destination webpage and loads it.
For example, a link from your homepage to your Contact page tells the browser where to find that page.
Links are important because they help visitors navigate your website and help search engines discover and understand the relationship between your pages.
How Do Websites Work on Mobile Phones?
The basic process is the same whether someone visits your website from a computer, tablet or smartphone.
The difference is how the website is displayed.
Modern websites are generally designed to be responsive, meaning the layout adjusts to different screen sizes.
A good mobile website should make it easy to:
- Read the content
- Navigate the website
- Tap buttons
- Complete forms
- Find contact details
- Make purchases where applicable
Your website should therefore be designed for mobile users as well as desktop visitors.
How Do Search Engines Find Websites?
Search engines such as Google use automated software called crawlers to discover and analyse websites.
A crawler can follow links between pages and collect information about the content it finds.
Search engines then use this information, along with many other factors, to determine which pages may be useful for particular searches.
This is why your website's structure, content, links and technical setup can all matter for SEO.
Having a website does not automatically mean it will appear prominently in Google.
How Does Google Know What a Website Is About?
Search engines look at the information available on your website to understand its content.
This can include:
- Page titles
- Headings
- Written content
- Links
- Images
- Website structure
- Structured data
- Other technical information
Clear, useful content makes it easier for both visitors and search engines to understand what each page is about.
What Is HTTPS?
You may have noticed that website addresses often begin with https://.
HTTPS helps protect information transferred between a visitor's browser and the website.
It is particularly important for websites that collect information through forms, accept payments or allow customers to log in.
Modern websites should use HTTPS to provide a secure connection.
Where Does a Website Builder Fit In?
A website builder brings many of these elements together.
Instead of having to arrange your own hosting, build the technical structure of the website and manage everything separately, a website builder can provide tools for creating and managing your website in one place.
Depending on the website builder, this may include:
- Website design tools
- Hosting
- Domain connection
- Content management
- SEO tools
- Security
- Forms
- Ecommerce
- Website support
The exact features vary between website builders, so it's important to understand what is included before choosing one.
What Happens When You Update Your Website?
When you edit your website, you're changing the information stored as part of your website.
For example, you might:
- Add a new page
- Change your business details
- Replace an image
- Add a new product
- Update your services
- Publish a blog article
Once the changes are published, visitors can request the updated version of the page from your website's server.
This means you don't need to create an entirely new website every time something changes.
How Websites and the Internet Work Together
A website is only one part of the larger internet.
The internet provides the network that connects computers and devices around the world.
Your website is stored on a server connected to that network. Your domain provides an easy-to-remember address, while your browser allows visitors to request and view your website.
In simple terms:
Domain → identifies your website
Hosting → stores your website
Website → contains your pages and content
Browser → displays your website
Internet → connects visitors to your website
Search engines → help people discover your website
Do You Need to Understand All of This to Build a Website?
No.
You don't need to understand servers, code or internet infrastructure to create a website.
Website builders are designed to handle much of the technical work behind the scenes so you can concentrate on your pages, content, design and customers.
Understanding the basics is still useful, however, because it helps you make better decisions when choosing how to build and manage your website.
Websites Don't Have to Be Complicated
At first, the technology behind a website can seem complicated.
But the basic concept is relatively simple.
Your website is stored on a server, your domain gives people a way to find it, and a browser retrieves and displays the information when someone visits.
Website builders make the process of creating and managing that website much easier by handling many of the technical details for you.
