Website Terminology: Key Terms to Know Before You Start

Before launching a new digital project, it’s important to understand the website terminology you’ll encounter. This guide will walk you through the most essential web terms to help you navigate the world of websites and communicate effectively with your team or development partner.

Whether you’re building from scratch or revamping an existing site, knowing these terms improves collaboration and reduces time wasted in back-and-forth communication. Even if you’re hiring an agency or freelance expert, understanding web design terms helps you make informed decisions and ask the right questions.

Basic web design terminology

Let’s start with the basics. These terms relate to how your website looks and feels — the visuals, structure, and user interaction. Understanding them will help you make smarter decisions when working with designers or choosing a design approach for your site.

UI (user interface)

UI stands for user interface — the visual layout of a digital product. It’s a crucial part of web page design terminology that covers everything users interact with on a screen. Need help with interfaces? Explore our UI/UX design services.

UX (user experience)

UX focuses on how users experience a website or app. This aspect of web design terms is essential for increasing engagement and retention by making interfaces intuitive and enjoyable to use.

Wireframe

A wireframe is an early-stage layout that outlines the structure of a website. It’s a key concept in website design terminology, helping designers and clients align before development begins.

Responsive design

Responsive design means your website adjusts to all screen sizes — desktop, tablet, and mobile. It’s a critical part of website building terminology, especially for modern SEO and performance..

Layout

Layout refers to how elements are arranged on a page — headlines, images, CTAs, and more. A clean layout supports better UX and is central to professional web page terminology.

Website development terminology

This section covers the core technologies and tools behind how websites actually work. These terms explain how websites are built, managed, and made interactive — from code to servers. Whether you’re collaborating with developers or trying to understand what’s under the hood, these concepts are key.

Frontend vs backend

Frontend is the user-facing part (HTML, CSS, JS); backend is the server side (databases, APIs, logic). Understanding both is essential in mastering website development terminology.

HTML, CSS, and JavaScript

These are the building blocks of the web:

• HTML defines the structure.
• CSS handles styling.
• JavaScript adds interactivity.

All three are fundamental to any web development terminology guide.

Content management system (CMS)

A CMS lets non-technical users update content without code. WordPress, for instance, is a widely used CMS in both marketing and ecommerce projects.

API (application programming interface)

APIs connect different systems together — like your website and CRM. They’re core to web service terminology and are critical for scalable development. Dive deeper into our API development services.

Web hosting

Hosting is the foundation of a live site. It affects speed, uptime, and data security. Choose reliable providers to support your infrastructure.

Ecommerce & marketing terminology

In this section, we explore key terms used in online sales and digital marketing. These concepts are essential if you’re building an online store, running campaigns, or tracking conversions. Understanding them will help you collaborate with marketing teams, choose the right tools, and optimize your website for performance and sales.

Ecommerce platform

An ecommerce platform helps you run an online store. Popular options include Shopify, WooCommerce, and BigCommerce. Want something mobile-first? Our mobile app development team can help.

SSL certificate

SSL ensures your site is secure. It’s essential for customer trust and data safety — especially on ecommerce platforms.

SEO (search engine optimization)

SEO makes your site visible in search engines. Key elements include metadata, speed, structured content, and backlinks. It’s a fundamental term across website terminology guides.

CTA (call to action)

CTAs guide users to take specific steps — like “Contact Us” or “Buy Now.” They’re one of the most important parts of website terms aimed at increasing conversions.

Landing page

A landing page is created to drive a specific action, often tied to a campaign. It differs from a homepage and focuses on a single message.

Advanced website features and terms

As websites evolve, they often require more than just static pages. This section covers advanced features and technologies that enable dynamic content, app-like behavior, faster loading, and more personalized user experiences. Understanding these terms helps you explore what’s possible beyond a basic website.

Web applications

A web application is an interactive site that behaves like software — think dashboards, CRMs, or booking tools. This is part of web application terminology that’s vital for modern SaaS and product development.

PWA (progressive web app)

PWAs offer app-like features in the browser: offline access, push notifications, and installability. They combine mobile convenience with web reach.

AMP (accelerated mobile pages)

AMP is designed for blazing-fast content loading on mobile devices. It’s especially useful for content-heavy platforms like blogs or media outlets.

SEO-friendly design

Design and structure that follow SEO best practices (fast load time, clean code, responsive UI) fall under web design terminology and help your site rank better.
