- Understanding basic website terminology helps you choose the right builder, fix problems faster and grow your traffic.
What Is a Website Builder?
A website builder is an online platform that lets you create and publish a website without writing code. You choose a template, customize it with a drag-and-drop editor, and go live in a few clicks. Most website builders include hosting, a free SSL certificate and a way to connect your own domain name.
Basic Website Builder Terms
Domain Name
Your domain name is the address people type to find your website, like hostinginfos.com. Pick something short, memorable and easy to spell.
Custom Domain
Many builders give you a free address such as yoursite.builder.com. A custom domain replaces it with your own name, like yourbrand.com. It looks more professional and builds trust with visitors.
Subdomain
A subdomain is a section added in front of your main domain, like blog.yoursite.com or shop.yoursite.com. It’s useful for keeping a separate area of your site on its own.
URL
A URL is the full address of one specific page, for example yoursite.com/about. Think of your domain as the building and the URL as the exact room.
Web Hosting
Web hosting is the server space where your website’s files are stored and served to visitors. Website builders usually include hosting, while self-hosted platforms need a separate hosting plan.
DNS (Domain Name System)
DNS works like the internet’s phone book. It translates your domain name into the server address where your site lives, so browsers know where to find it.
CMS (Content Management System)
A CMS is software that lets you create, edit and organize website content without coding. Website builders like Wix and Squarespace have a built-in CMS.
WordPress
WordPress is the world’s most popular open-source CMS. It’s more flexible than most website builders, but you’ll usually need to arrange your own web hosting.
No-Code
No-code means building websites or apps with visual tools instead of programming. Every modern website builder is a no-code tool.
Web Design Terms
Template
A template is a pre-designed page layout you customize with your own content. Starting from a template saves time and gives you a professional base.
Theme
A theme controls your site’s overall look, including colors, fonts, buttons and spacing. People often use “template” and “theme” interchangeably, but a theme usually applies to your whole site.
Drag-and-Drop Editor
A drag-and-drop editor is the visual workspace where you build pages by moving elements into place. What you see while editing is what visitors will see.
Responsive Design
Responsive design means your website automatically adjusts its layout to fit any screen, from phones to wide desktop monitors. Since most web traffic now comes from mobile devices, a responsive site is essential.
Mobile-First Design
Mobile-first design means planning pages for small screens first, then expanding them for larger ones. It keeps your content focused on what matters most.
Header and Footer
The header is the top section of every page, usually holding your logo and main menu. The footer sits at the bottom with contact details, social links and legal pages.
Hero Section
The hero section is the large banner at the top of a page, often with a headline, an image and a button. It’s your visitor’s first impression.
Above the Fold
Above the fold refers to the part of a page visitors see before scrolling. Put your main message and call to action here.
Navigation Menu
A navigation menu is the set of links visitors use to move around your website. Keep it short and clearly labeled.
Breadcrumb Navigation
Breadcrumbs show a visitor’s path through your site, like Home > Blog > This Post. They improve usability and help search engines understand your site structure.
Grid Layout
A grid layout arranges page elements into rows and columns so everything lines up neatly. Most website templates are built on a grid.
Typography
Typography covers the fonts, sizes and spacing of your text. Good typography improves readability. Two fonts, one for headings and one for body text, is usually enough.
Wireframe
A wireframe is a basic sketch of a page layout made before colors and images are added. It helps you plan structure before design.
Favicon
A favicon is the small icon shown in browser tabs and bookmarks. It makes your site look complete and easier to recognize.
UI and UX
UI (user interface) is what visitors see and click, like buttons and menus. UX (user experience) is how easy and enjoyable your site is to use overall.
Web Accessibility
Web accessibility means designing your site so everyone can use it, including people who rely on screen readers or keyboards. The W3C Web Accessibility Initiative offers free guidelines to follow.
Website Content and Feature Terms
Blog
A blog is a section of your website with regularly published posts. Blogging is one of the best ways to share expertise and attract search traffic over time.
Landing Page
A landing page is a standalone page built for one goal, like collecting sign-ups or promoting a product. It usually has no menu so visitors stay focused.
CTA (Call to Action)
A CTA is a button or line of text that tells visitors what to do next, such as “Get Started” or “Book a Call.” Every key page should have one clear CTA.
Web Form
A web form is a set of fields visitors fill in to contact you, subscribe or place an order. Shorter forms get more completions.
Widget
A widget is a small, ready-made content block, like a search bar, social feed or recent posts list, that you can add to a page.
Plugin
A plugin is an add-on that gives your website new features, such as booking systems or SEO tools. Install only what you need, since too many plugins can slow your site.
Integration
An integration connects your website builder to another tool, such as an email marketing service, CRM or payment provider.
Embed Code
Embed code is a snippet that displays outside content, like a YouTube video or Google Map, on your page.
Dynamic Content
Dynamic content changes based on who’s viewing it or when. Personalized greetings and product recommendations are common examples.
Static Website
A static website shows the same fixed content to every visitor. Static sites are fast and secure, which makes them ideal for portfolios and small business sites.
Alt Text
Alt text is a short written description of an image. Screen readers read it aloud, and search engines use it to understand the image.
SEO Terms for Website Builders
SEO (Search Engine Optimization)
SEO is the process of improving your website so it ranks higher in search engines like Google. Helpful content, fast pages and clear structure are the foundation.
Keyword
A keyword is a word or phrase people type into search engines. Using the right keywords in your content helps the right audience find your pages.
Title Tag
The title tag is the clickable headline shown for your page in search results. Keep it under about 60 characters and include your main keyword.
Meta Description
A meta description is the short page summary that often appears under your title in search results. It doesn’t directly affect rankings, but a strong one earns more clicks.
Permalink
A permalink is the permanent URL of a page or post. Keep permalinks short and descriptive, like yoursite.com/website-builder-glossary.
Backlink
A backlink is a link from another website to yours. Links from trusted, relevant sites are one of the strongest signals search engines use to rank pages.
XML Sitemap
An XML sitemap is a file that lists your site’s pages for search engines. You can submit it through Google Search Console to help your pages get indexed faster.
Robots.txt
Robots.txt is a small file that tells search engine crawlers which parts of your site to crawl and which to skip.
301 Redirect
A 301 redirect permanently sends visitors and search engines from an old URL to a new one. Use it whenever you move or rename a page to keep your traffic and rankings.
404 Error
A 404 error is the “page not found” message shown when a link is broken or a page no longer exists. A helpful custom 404 page keeps visitors on your site.
Website Speed and Performance Terms
Page Speed
Page speed is how fast your web pages load. Faster sites keep visitors engaged and tend to rank better in search results.
Core Web Vitals
Core Web Vitals are Google’s metrics for measuring loading speed, responsiveness and visual stability. You can learn how they work on web.dev.
CDN (Content Delivery Network)
A CDN is a network of servers around the world that stores copies of your site’s files. It delivers content from the server closest to each visitor, so pages load faster.
Image Compression
Image compression reduces image file sizes without visibly lowering quality. Oversized images are one of the most common causes of slow websites.
Lazy Loading
Lazy loading delays loading images and videos until visitors scroll near them, which makes pages appear faster.
Minification
Minification removes unnecessary spaces and characters from code files to make them smaller and quicker to load.
SVG
SVG is a vector image format built from shapes instead of pixels, so it stays sharp at any size. It’s ideal for logos and icons.
Website Security Terms
SSL Certificate
An SSL certificate encrypts data traveling between your website and its visitors. Most website builders include a free SSL certificate.
HTTPS
HTTPS is the secure version of HTTP, enabled by SSL. The padlock in the browser’s address bar shows visitors your site is safe.
Website Backup
A backup is a saved copy of your website’s files and content. Regular backups let you restore your site quickly after an error or attack.
Website Analytics Terms
Google Analytics
Google Analytics is a free tool that shows who visits your website, where they come from and what they do there.
Bounce Rate
Bounce rate is the percentage of visitors who leave after viewing only one page. A high bounce rate can point to slow loading or content that doesn’t match what visitors expected.
Conversion Rate
Conversion rate is the percentage of visitors who complete a goal, such as buying a product or submitting a form.
E-commerce Terms
E-commerce
E-commerce means selling products or services online. Many website builders include store features like product pages and secure checkout.
Shopping Cart
A shopping cart holds the items a customer has chosen until they’re ready to check out.
Payment Gateway
A payment gateway securely processes online card and wallet payments between your customer, your store and the bank. Stripe and PayPal are common examples.

CSS
CSS controls how a web page looks, from colors and fonts to spacing and layout.
JavaScript
JavaScript is the programming language that adds interactivity, such as sliders, pop-ups and live form checks.
Frontend and Backend
The frontend is everything visitors see in their browser. The backend is the server side that stores data and runs processes behind the scenes.
API
An API (application programming interface) lets two pieces of software exchange data, such as your website and a payment gateway.
DOM
The DOM (Document Object Model) is the browser’s structured map of a web page, which scripts use to read and update content.
