What is a Website? The Complete Beginner’s Guide
Table of Contents
Small businesses across the UK face a consistent challenge: establishing a digital presence without getting lost in technical jargon. More than ever, it’s important for small businesses to get online. However, many business owners aren’t tech whizzes. To help, we like to strip things back to the absolute basics. So, what is a website?
Websites are an essential tool for reaching new customers and maintaining competitiveness. With 67.8 million individuals using the internet in the United Kingdom and 78% of UK SMEs having a website, understanding these fundamentals will help you make informed decisions about your digital strategy.
What is a Website?

Technically, a website is nothing more than a collection of text files hosted on a server somewhere. However, for business owners, it’s more helpful to think of your website as an online platform for your customers to interact with you.
To define a website, it’s helpful to consider what types of people would have a website. Anyone and everyone can have a website, including businesses of all sizes and types, non-profit organisations, charities, governments, religious organisations, individual people, celebrities, musicians, entertainers, and entertainment venues.
The Birth of the World Wide Web
The story of websites began in the 1960s with the advent of packet-switching technology, which enabled the transmission of data packets over a network of interconnected computers. This laid the foundation for the creation of ARPANET, the precursor to the internet, in 1969.
In the 1980s, a young physicist at CERN, Tim Berners-Lee, envisioned a system for sharing information across the network in a more user-friendly manner.
In 1991, Berners-Lee developed the Hypertext Markup Language (HTML), the foundation of web page creation, and the Hypertext Transfer Protocol (HTTP), the protocol that governs communication between web servers and browsers. He also created the first web browser, WorldWideWeb (www), and the first web server on the NeXT computer.
Website vs Web Page vs Search Engine
Many people use these terms interchangeably, but understanding the distinctions helps when discussing your digital strategy.
| Term | Analogy | Definition | Example |
| Website | The Book | The entire collection of related content | bbc.co.uk (entire site) |
| Web Page | A Single Page | One document within the website | bbc.co.uk/news/technology |
| Web Browser | The Reading Device | Application to view websites | Chrome, Safari, Firefox |
| Search Engine | The Librarian | Tool that finds websites | Google, Bing |
One mistake that people commonly make is saying they “open Google” to visit a website. Rather, they open a browser (like Chrome), then use Google as a search engine within the browser to find the website they want.
How Websites Actually Work: The Simple Explanation
Creating a website can be a fraught process, especially if you don’t have great knowledge of the technical side. Understanding the basics helps business owners communicate effectively with web designers and avoid costly mistakes.
Technical jargon can be intimidating. To understand how a website functions, it’s best to look at it like real estate. If you want to build a house, you need three things: land, an address so people can find you, and the building itself. The internet works the same way.
The Domain Name: Your Digital Address
Just as your home has a street address (e.g., 31 Henry Place, Belfast), a website has a domain name (e.g., profiletree.com). Without a domain, users would have to navigate using an IP address—a string of numbers like 192.158.1.38—which is impossible to remember.
In the UK, .co.uk is still the most trusted domain extension, though .com remains the global standard. The .uk domain accounts for 11.1 million domains, making it the second most popular European TLD. Domain registration typically costs £5-15 annually for .co.uk domains.
Web Hosting: The Land Beneath Your Website
A house needs land to sit on. Similarly, a website needs web hosting. Hosting is space rented on a powerful computer called a server, connected to the internet 24/7, keeping your site accessible day and night. If you stop paying for hosting, your website disappears from the internet.
The Site Files: Your Digital Building
Once you have the address and land, you need the building itself. A website comprises code files (HTML, CSS, JavaScript) and media assets (images, videos, text).
- HTML: The structure—like bricks and mortar. It defines headings, paragraphs, images, and links.
- CSS: The design—like paint and decoration. It controls colours, fonts, spacing, and layout.
- JavaScript: The functionality—like electricity and plumbing. It adds interactive elements such as forms and animations.
When visitors type your domain into their browser, the hosting server sends these files to their device, which assembles them into the visual page they see.
The Anatomy of a Modern Website

In 2025, websites are complex applications with sophisticated functionality. Modern websites are split into two distinct areas: the frontend and backend.
The Frontend: What Users See
This is everything users interact with. When you hover over a button and it changes colour, or when images slide across the screen, you’re seeing frontend code. This includes HTML, CSS, JavaScript, responsive design frameworks, and visual branding.
With mobile devices accounting for over 61% of global website traffic, frontend design must prioritise mobile-first approaches. Websites optimised for mobile load 1.8 seconds faster than non-optimised sites.
The Backend: The Engine Room
The backend operates behind the scenes, handling data processing, user authentication, database queries, and business logic. For example, when customers log into your website, the backend checks credentials against the database and grants access accordingly.
The backend handles processing contact forms, managing user accounts, handling e-commerce transactions, storing and retrieving data, and sending automated emails.
Static vs Dynamic Websites
Static Websites: Early websites were static—fixed HTML pages showing the same content to everyone. Changes required manually editing code files. These suit simple brochure sites but offer limited functionality.
Dynamic Websites: Modern websites are dynamic, generating content on-demand from databases. Content Management Systems (CMS) like WordPress power 43.2% of all websites, allowing non-technical users to update content without coding knowledge.
Progressive Web Apps (PWAs): The latest evolution, PWAs combine website accessibility with app-like functionality, working offline and sending push notifications. This represents the future for businesses seeking competitive advantages.
Types of Information on Websites
A website contains a variety of types of material. Often, this takes the form of written content. Some websites include a feature that translates the content into another language or multiple languages, particularly useful for businesses serving international markets.
Websites also contain graphics such as artwork and photographs, as well as audio, video, animation, and more. With video content, visitors stay up to 88% longer on websites, making it a powerful engagement tool.
Business websites contain essential information about the business itself—location, services, history—plus information for job seekers, such as career details, job listings, and digital application forms.
How People Can View and Access Websites
People first need internet access to reach websites. They type a website’s address (URL) into the address bar in an internet browser, or find sites through search engines or links from other sites. This is where Search Engine Optimisation (SEO) becomes critical—helping your website appear when potential customers search for products or services you offer.
People use a variety of electronic devices to view websites. These can be desktop computers, laptop computers, tablets, or mobile phones. The experience varies based on device—a desktop monitor shows more content at once than a mobile phone screen.
Most websites respond to screen size, automatically adjusting layouts and content. This is called responsive design, and it’s no longer optional—it’s essential. Mobile devices contribute 61.6% of global website traffic as of 2025, up from 58.3% in 2024. Websites optimised for mobile experience 48% higher engagement rates than non-optimised counterparts.
Purpose of Websites

Websites serve many purposes, and understanding these helps business owners define clear objectives:
- Entertain users: Engaging content keeps visitors on your site longer
- Persuade visitors to buy: E-commerce functionality enables direct sales
- Market or sell services: The primary purpose for most business websites—generating leads and sales
- Inform visitors: Educational content positions your business as an expert and builds trust
- Provide customer service: Self-service support through FAQs and knowledge bases
The purpose of some websites is primarily to sell products or services. So much shopping takes place through websites. Shoppers can easily move, or navigate, through online stores and make purchases with various payment methods. Websites have built-in security features that make shopping on the internet secure.
Promotional Websites
Some websites are somewhat similar in content and purpose to paper brochures, as they contain some informational and promotional content. However, a website is much more than that, and one of the beauties of a website is that it can be updated much more readily than any paper document can be. You might even update your site on a regular basis.
Many websites feature blogs, which include articles like a magazine. Blog posts can be varying lengths and can be posted to a website as often as desired. Websites with blogs have 434% more indexed pages, enhancing their visibility in search engine results, while businesses that blog generate 67% more leads per month compared to those that don’t.
Those are just some of the possible purposes of a website. A website can serve any purpose that the creator of that website has in mind. These days, most websites have a combination of all of these features.
8 Common Types of Websites (With UK Examples)
Different business models require different website types. Understanding these categories helps clarify requirements when briefing a web design agency or evaluating your current site.
- Business Websites: Traditional company sites providing information about services, team, and contact details. Essential pages include Homepage, About Us, Services, Contact, Privacy Policy, and Cookie Consent (GDPR requirement).
- E-Commerce Websites: Online shops allowing customers to browse products, add items to baskets, and complete secure transactions. UK Example: John Lewis online.
- Portfolio Websites: Showcase work examples for creative professionals, agencies, and freelancers. Best for photographers, web designers, marketing agencies, and architects.
- Blog and Content Websites: Content-focused sites providing articles, guides, and resources. UK Example: BBC’s news section.
- Lead Generation Websites: Designed to capture potential customer information through forms, offering valuable resources in exchange.
- Membership Websites: Restricted-access sites requiring user registration, providing exclusive content or services to members.
- Non-Profit Websites: Focus on mission communication, volunteer recruitment, and donation collection.
- Landing Pages: Single-page websites designed for specific marketing campaigns, focusing visitors on one conversion goal.
Website SEO: Getting Found by Customers
The most beautiful website delivers no business value if potential customers can’t find it. Search Engine Optimisation (SEO) determines whether your website appears when people search for products or services you provide.
With more than 1.13 billion websites globally and 11.1 million .uk domains, competition for search visibility is intense. Google.com receives 92.5 billion visits monthly, making search engines the primary way people discover businesses online.
SEO Fundamentals
On-Page SEO: Includes title tags (clickable headlines in search results), meta descriptions (persuasive summaries), heading structure (logical H1, H2, H3 hierarchy), and internal linking (strategic links between your pages).
Technical SEO: Site speed directly impacts rankings—Google.com’s average load speed of 0.77 seconds made it the UK’s fastest loading website. Mobile responsiveness is non-negotiable, with Google using mobile-first indexing. SSL certificates (HTTPS) are ranking factors and required for sites collecting information.
Local SEO: Businesses serving Northern Ireland, Ireland, and broader UK markets need location-specific optimisation including Google Business Profile optimisation, local citations, location pages, customer reviews management, and local link building.
ProfileTree specialises in local SEO, helping Belfast and regional businesses compete effectively in their specific markets rather than getting lost competing nationally.
What are Website Cookies?
A cookie is a piece of information that your computer or other electronic device receives from a website you visit. Your computer stores that information, then sends that same information back to the website you visited.
Cookies can be both useful and problematic. They make it straightforward to access websites and can be challenging if not properly managed. Websites use cookies to monitor your browsing activity, making shopping experiences more enjoyable and efficient. Cookies also keep track of logins, making them seamless and quick.
Another helpful task that cookies perform is keeping track of a user’s visits to the website where a person would log in, thus making their logins more seamless and quick.
Cookie Consent and GDPR
UK websites must obtain explicit consent before placing non-essential cookies on visitors’ devices. This is a legal requirement under GDPR. Implementation requires a cookie banner on first visit, clear explanation of cookie purposes, accept/reject options, and a cookie policy page.
Different computers have different settings, but there are ways to view and modify cookie settings within internet browsers. Although some cookies can be harmful, many are helpful, making browsing experiences better.
Website Development Options: DIY vs Professional

Creating a website has become simpler for non-technical people. However, businesses should understand the trade-offs between different approaches.
The Quick Fix Warning
In the early internet days, creating a website was complicated and expensive. Now there are tools that make it quick and easy to set up websites. However, businesses should beware ‘quick fix’ websites as these can be badly set up for user experience and search engine optimisation.
This might prevent you from reaching your goals. You’ll then have to engage an agency to create a proper website. In the long run, this wastes time and potentially money. As such, it’s crucial to do your research and invest in the right website from the outset.
When DIY Website Builders Work
Website builders like Wix, Squarespace, and Weebly have their place for very limited budgets (under £500 total), simple requirements (basic brochure sites), no immediate need for search traffic, and personal projects.
While it’s possible to create a site which looks great using a website builder, there are many functional elements which you may have insufficient knowledge of. For example, it will take you a long time to understand metadata and internal linking. Additionally, DIY websites rarely compete with professionally designed sites for search rankings or conversion rates.
When Professional Web Design Is Essential
Professional web design becomes necessary when lead generation is critical, you’re competing in crowded markets, e-commerce functionality is required, you need strategic input on content and user experience, integration with business systems is needed, professional brand image matters, or you want to rank well in search engines.
The Evolution: From Static Brochures to Dynamic Digital Hubs
Back in the day, websites were predominantly static online brochures, serving as digital storefronts for businesses to showcase their products and services. These early websites were primarily informational, providing basic company details, contact information, and product descriptions. However, the rapid advancements in technology, coupled with the ever-increasing demands of users, have propelled websites into sophisticated digital ecosystems that play a pivotal role in modern business operations.
The Rise of Interactive Experiences
The evolution of website functionality is marked by a transition from passive information delivery to interactive user experiences. Websites now incorporate a range of dynamic features that engage users, enhance their browsing experience, and facilitate seamless interactions with businesses. These interactive elements include:
- User-friendly navigation: Websites now employ intuitive navigation menus, search functions, and breadcrumb trails to help users easily find the information they need.
- Rich media content: Videos, images, and interactive graphics have become integral components of websites, captivating users’ attention and conveying information in a more engaging manner.
- Real-time data integration: Websites are increasingly integrated with real-time data streams, such as live chat features, social media feeds, and dynamic product updates, providing a more personalised and responsive user experience.
The Integration with Sales and Service
Websites have transcended their initial role as mere online brochures and have become integral components of sales and service strategies. Websites now seamlessly integrate with customer relationship management (CRM) systems, enabling businesses to:
- Capture and manage customer data: Websites collect user information through forms, subscriptions, and purchase transactions, allowing businesses to build detailed customer profiles.
- Nurture leads and drive conversions: Websites incorporate lead capture mechanisms, email marketing automation, and personalised content recommendations to guide users through the sales funnel.
- Provide self-service support: Websites offer knowledge bases, FAQs, chatbots, and interactive troubleshooting tools, empowering customers to find solutions independently.
Emerging Trends and Future Directions
The evolution of website functionality is far from over. As technology continues to evolve and user expectations rise, websites are poised to become even more sophisticated and integrated into the fabric of business operations. Emerging trends include:
- Voice search and conversational interfaces: Websites are adapting to voice search, enabling users to interact with websites through natural language commands.
- Artificial intelligence (AI) and machine learning (ML) integration: AI and ML are being used to personalise user experiences, provide predictive recommendations, and automate customer service interactions.
- Augmented reality (AR) and virtual reality (VR) integration: AR and VR technologies are being explored to create immersive experiences that allow users to virtually interact with products and services.

Website Development and Maintenance Retainer Models
Website development and maintenance retainer models are agreements between businesses and web design firms that provide ongoing website support and enhancement services for a fixed monthly fee. These retainer models offer several benefits for both parties:
Benefits for Businesses
- Predictable Costs: Businesses can budget for ongoing website support and enhancements without the uncertainty of hourly or project-based pricing.
- Proactive Maintenance: Retainer models ensure that websites are regularly updated, maintained, and optimised, minimising downtime and security risks.
- Priority Support: Businesses receive priority access to support for technical issues, bug fixes, and updates.
- Enhanced Engagement: Ongoing website enhancements help businesses keep their websites fresh, engaging, and aligned with their evolving marketing goals.
Benefits for Web Design Firms
- Recurring Revenue: Retainer models provide a steady stream of income, enabling web design firms to plan their resources effectively.
- Long-Term Client Relationships: Retainer models foster strong client relationships and encourage repeat business.
- Reduced Client Churn: The predictability and value of retainer models help reduce client churn and increase customer retention.
Common Retainer Models

Choosing the Right Retainer Model
The choice of retainer model depends on the size, complexity, and ongoing needs of the website. Businesses should consider their website’s traffic, frequency of updates, and desired level of support when selecting a retainer package.
“Many business owners underestimate the ongoing investment required for website success. A website isn’t a set-and-forget asset—it’s a living marketing tool requiring regular attention, content updates, and technical maintenance to deliver consistent results. The businesses seeing the strongest returns from their digital presence are those treating their website as an evolving platform rather than a finished product,” says Ciaran Connolly, Director of ProfileTree.
FAQs
What is the typical duration of a website development and maintenance retainer agreement?
The duration of a retainer agreement can vary depending on the specific needs and preferences of the business and the web design firm. However, retainer agreements typically range from 6 months to 2 years.
What happens if I need additional services outside of the scope of my retainer agreement?
If you require additional services beyond what is included in your retainer package, you may be charged an hourly rate or a project-based fee. It is important to discuss this with your web design firm upfront to ensure there are no surprises.
How can I track the progress of my website maintenance and enhancements?
Web design firms typically provide regular reports to clients outlining the work completed, any issues identified, and upcoming tasks. Additionally, you can request access to a project management tool to track progress and communicate with your web design team.
What are the key considerations when selecting a web design firm for a retainer agreement?
When choosing a web design firm for a retainer agreement, consider their experience, expertise, communication style, and ability to understand your specific needs. It’s also important to review their portfolio and client testimonials to assess their quality of work and customer satisfaction.
