From social media platforms and eCommerce websites to blogs and professional portfolios, websites serve many purposes for website owners and developers alike. But how do websites work? What exactly happens when you type a website address into your browser tab?
This comprehensive guide answers those questions by explaining the entire process in clear, accessible terms. It covers essential topics such as domain names, the site structure, web development, web server communication, http requests and IP addresses.
Designed for beginners and those looking to expand their technical knowledge, this guide offers valuable insights for website visitors, developers and anyone curious about how websites operate and how to create content that engages a target audience effectively.
What is a website?
To grasp how websites function, you must first understand what a website is. Essentially, it is a set of web pages located on a server. These web pages have text, images, videos and interactive elements. They aim to provide a seamless user experience.
There are several uses for websites. They facilitate social interactions, internet commerce and information provision.
When a user with an internet connection enters a website address into their browser, it involves many steps to retrieve and display the page. The Domain Name System (DNS) translates a domain name into an IP address. This lets the browser find the website’s server.
Once connected, the server delivers HTML code, CSS files, JavaScript files and other resources that make up the webpage.
Technical nuances: Websites are hosted on physical computers, often called servers, provided by web hosting providers. These servers store all the resources to run the website. When a user enters a web address, they ensure that the server can send the files needed to display the page.
How is a website built?
Building a website involves several key steps to create a professional online presence quickly and efficiently:
- Define purpose & audience: Establish clear goals and a cohesive brand identity.
- Plan site structure: Create essential webpages like home, landing and contact pages.
- Design visuals: Choose color schemes, fonts and layouts aligned with the brand.
- Develop webpages: Use HTML, CSS and JavaScript to build responsive, user-friendly pages compatible with multiple browsers and mobile devices.
- Host website: Upload website files to a reliable web server via a trusted hosting provider.
- Optimize for performance: Compress images and craft meta descriptions to improve site speed and search engine rankings.
Typically, this entire process takes one to two weeks, depending on complexity and whether server-side processing is needed for dynamic sites. For many beginners, walking through these steps turns their abstract question ‘what is a website?’ into a practical, hands-on project.
Following these streamlined steps ensures your website is effective, accessible and ready to engage visitors. Once that foundation is in place, it becomes much easier to operate website updates, add new pages and refine your design over time.
What are web pages?
Web pages play a significant role in contributing to the overall web development process. These are individual documents that make up a website. Each page is written in HTML code and is designed to display various types of content, including text, images and videos.
For example, a homepage may display company information, while a product page may showcase individual products with descriptions and images.
The page elements of a web page are controlled by CSS files, which define the layout, color scheme and fonts.
JavaScript files add interactivity, such as animations, drop-down menus and form validation. Together, these components make web pages both functional and visually appealing.
Technical nuances: A web page’s structure is defined using HTML code, while its appearance is styled using CSS files. JavaScript files handle interactive features, allowing users to engage with the content dynamically. These files are loaded from the server and displayed in the browser.
The role of web hosting
Today, every website needs a place to live on the internet. This is where web hosting comes in.
A web hosting service offers the server space and technology required to store and deliver website files on the internet. Without hosting, a website’s web pages wouldn’t be accessible to users over the internet.
Any clear explanation of ‘how do websites work’ has to include hosting, because the server is what actually stores and serves your site’s files.
When a website is hosted, its files – including HTML code, CSS files and JavaScript files – are stored on a physical computer called a server.
When users access the website, the server delivers all the resources required to load the web pages. This entire process is managed by web hosting providers like Bluehost, who ensure that the server is always connected to the internet and accessible.
Types of hosting services:
- Shared hosting: Various websites share the same server resources. It’s cost-effective but limited, ideal for small sites. For better performance, our managed WordPress hosting optimizes resources automatically, ensuring faster load times, better reliability and easy scalability as your site grows. Build and launch impressive WordPress sites effortlessly with intelligent, adaptive tools.
- Dedicated hosting: A dedicated server hosts a single website. It has more significant resources and performance. This is suitable for larger websites with high traffic.
- Cloud hosting: Website files are stored across multiple servers in a cloud network, ensuring better scalability and uptime. This makes it an excellent choice for website agencies that manage multiple clients and need reliable performance. For more control, our VPS hosting provides dedicated resources and full customization for growing websites. It’s a powerful solution for businesses—and agencies—needing enhanced security and performance.
Technical nuances: Web hosting ensures that a website’s files are available 24/7. The server is responsible for responding to user requests and sending back the HTML code, images and other resources needed for the browser to display the web pages.
How do websites work?
Understanding the basics of how do websites work can help you appreciate the complexity behind the scenes.
Whenever a user enters a website address into their browser, it starts a series of actions to retrieve and display the site’s page content.
1. DNS query
When a user types a domain name (for example, www.bluehost.com), the browser sends a DNS request to look up the corresponding IP address. The Domain Name System server acts as an address book, matching the domain name to the correct IP address.
2. Connection to the server
After locating the IP address, the browser requests the server hosting the webpage. This server stores all the resources to load the website. It has the HTML code, CSS files and JavaScript files.
3. Fetching website files
The server responds to the browser’s request by sending back all the necessary files, including HTML code, CSS files and images. These files are essential for rendering the page content in the browser.
4. Rendering the web page
Once the browser loads the files from the server, it processes the HTML code to create the webpage structure. The browser applies the CSS files to style the page and executes the JavaScript files to enable interactive features like forms or pop-up windows.
Technical nuances: This whole process involves several elements working together. The web browser first contacts the DNS server to resolve the domain name. It then connects to the hosting server, fetches the resources and displays the web page. This happens in milliseconds, making it appear seamless to the user.
Understanding DNS server: The phonebook of the web
The Domain Name System (DNS) is a crucial website component. It translates human-readable domain names into IP addresses, which are the numerical addresses used by servers and computers to communicate with one another.
Without DNS, users must remember complex IP addresses instead of simple domain names. DNS is a core part of understanding how do websites work at a technical level, since it quietly connects human-friendly names to machine-readable addresses.
The DNS server searches several servers for the IP address connected to a domain name entered by a user until it locates it.
This process involves several steps, as the DNS system is distributed across various servers worldwide.
Technical nuances: The DNS comprises multiple layers, including root servers, top-level domain (TLD) servers and authoritative DNS servers. Each layer directs the web browser to the correct server, ensuring that the website address is resolved quickly and accurately.
The browser’s role in displaying websites
Once the browser receives the response data from the server, it must process and display the web page. Browsers interpret the HTML code and render the page elements according to the instructions defined by the CSS files and JavaScript files.
- HTML parsing: The browser reads the HTML code to create the webpage’s structure, identifying headers, paragraphs, images and other elements.
- CSS styling: The browser applies styles defined in the CSS files to make the page visually appealing, determining the layout, colors, fonts and other design elements.
- JavaScript execution: If the webpage contains JavaScript files, the browser executes these scripts to enable interactive features like drop-down menus, forms and animations.
Technical nuances: Browsers use rendering to convert the HTML code and CSS files into a visual web page representation. This ensures that users see a fully functional and styled webpage when they access the site.
The importance of mobile optimization
As more users access websites via mobile phones, websites must be optimized for smaller screens. This is where responsive design comes into play.
Responsive design ensures that a website’s layout adjusts automatically based on the device being used, whether it is a tablet, mobile phone or desktop computer.
Technical nuances: CSS media queries are used by websites with responsive design to determine the screen size and modify the layout accordingly. This guarantees a smooth experience for users, irrespective of the device they use to visit the website.
A well-planned responsive layout also makes it more efficient to operate website content, because you don’t need separate designs for every screen size.
Dynamic vs. static websites
Websites are typically categorized as either static or dynamic, depending on how their content is delivered to users.
- Static websites: These websites deliver the same content to every visitor. The page content is pre-built and stored on the server, meaning there’s no need for server-side scripting.
- For example: A basic portfolio website showcasing static images and text remains the same for all users.
- Dynamic websites: These websites deliver content that changes based on user interactions or real-time data. The server generates Dynamic content on the fly, often pulling data from a database.
- For example: An eCommerce website shows different product recommendations based on the user’s previous purchases.
Technical nuances: Dynamic websites use server-side programming languages like PHP, Python or Node.js to generate real-time page content. These websites often rely on databases to store and retrieve the data necessary to customize the user experience.
The role of search engines in website discovery
Search engines like Bing, Yahoo and Google are essential for helping users discover websites. In fact, a lot of people who first search ‘what is a website’, end up clicking through to guides, tutorials and real examples from these results.
These platforms crawl and index web pages, making them searchable for users based on the content they seek.
For a website to rank well in search engine results, it must be optimized for search engines using Search Engine Optimization (SEO) techniques.
SEO best practices:
- Keyword optimization: Ensure that your web pages contain relevant keywords that users might search for. This significantly improves the chances of appearing in search results. For WordPress, Yoast SEO helps optimize content. It offers tools for improving SEO, including readability and keyword usage.
- Page speed: Optimize the speed at which your web pages load. Faster websites often rank higher in the search results.
- Mobile-friendliness: Due to search engines giving preference to mobile-friendly content, mobile-friendly websites perform higher in search engine rankings.
- Yoast SEO Plugin: For WordPress, Yoast SEO helps optimize content. It offers tools for improving SEO, including readability and keyword usage.
Technical nuances: Search engines use bots (or crawlers) to crawl websites and index their content. The bots analyze the HTML code, metadata and internal linking structure to determine a website’s relevance to specific search queries.
Web developers and their role in building websites
Web developers today are responsible for building and maintaining websites. They work on websites’ front end (what users see) and the back end (the server, database and application logic).
Their job is to ensure that the web pages are functional, visually appealing and easy to use.
- Front-end development: Front-end developers focus on the user-facing part of the website. They use HTML code, CSS files and JavaScript files to create interactive and visually appealing web pages.
- For example: A front-end developer ensures that a website’s navigation menu works seamlessly on both desktop and mobile devices.
- Back-end development: Back-end developers handle the website’s server side, ensuring that the server processes requests efficiently and retrieves the necessary data from the database.
- For example: A back-end developer ensures that user data is securely processed and stored when a user submits a form.
Technical nuances: Front-end development involves building the user interface, while back-end development focuses on the server, database and application logic. Together, front-end and back-end development ensure that a website functions smoothly.
The role of APIs in website functionality
Many modern websites use APIs (Application Programming Interfaces) to connect different services and features.
An API allows one system to communicate with another, allowing websites to pull data from external sources or integrate with third-party services.
For example: A weather website might use an API to pull live weather data from a third-party provider and display it on the homepage.
Technical nuances: APIs allow websites to request and receive data from other systems. This ensures that dynamic content is always up-to-date and relevant to the user.
Mobile apps and websites: How they work together
In the age of mobile applications, websites and apps often work in tandem to provide a seamless user experience. While websites are accessed via a browser, mobile apps provide a more tailored and personalized experience.
For example, an eCommerce business might offer both a website and a mobile app. Users can browse products on the website, while the mobile app provides push notifications and personalized offers.
Technical nuances: Both mobile applications and websites often pull data from the same servers using APIs. This ensures that the user experience is consistent across platforms, regardless of how they access the content.
How websites handle user data?
Users interact with websites and often input personal information, such as login credentials, shipping details or payment information. Websites must handle this data securely to protect user privacy and prevent unauthorized access.
Websites use secure connections (such as HTTPS) to encrypt the data transmitted between the browser and the server.
Additionally, many websites store user data in databases, ensuring that it is securely processed and retrieved as needed. These best practices are crucial if you operate website areas that handle logins, payment details or any other sensitive information.
Technical nuances: Websites use encryption protocols like SSL/TLS to secure user data during transmission. Server-side validation and database security measures are also implemented to protect user information from being compromised.
