1. Domain Name:
What it is: Your domain name is your website address. It is what people type into a browser to find you.
If your business is called Sunshine Bakery and your domain is www.sunshinebakery.co.za, that is your domain name. You register it separately from your website, usually for an annual fee, and it belongs to you as long as you keep renewing it.
A .co.za domain signals a South African business and tends to perform better in local search results than a generic .com if your audience is primarily based here.
2. Hosting:
What it is: Hosting is the service that stores your website files and makes them accessible on the internet around the clock.
Think of it this way. Your domain name is your business address. Hosting is the building that address points to. Without hosting, there is nowhere for your site to actually live.
Hosting is an ongoing monthly or annual cost, separate from your web design quote. The quality of your hosting affects how fast your site loads and how reliably it stays online. We have covered this in more detail in our post “What Is Website Hosting?“, and our “Hosting and Support” page explains what managed hosting includes.
3. SSL Certificate (HTTPS):
What it is: An SSL certificate encrypts the connection between your website and the person visiting it, keeping any information they submit safe.
You can tell if a site has SSL by looking at the browser bar. If the address starts with https:// rather than http://, it is secured. Most browsers now flag sites without SSL as “Not Secure”, which immediately puts visitors off.
Beyond security, Google uses SSL as a ranking signal. If your site does not have it, it is worth sorting out. Most reputable hosting providers include SSL as standard.
4. CMS (Content Management System):
What it is: A CMS is the software that powers your website and lets you manage its content without writing code.
When you log in to update a page, add a blog post or change a price, you are using your CMS. It is the behind-the-scenes system that makes your website editable.
Without a CMS, every change to your site would require a developer to edit the code manually. A good CMS puts reasonable control back in your hands.
5. WordPress:
What it is: WordPress is the most widely used CMS in the world, and the platform most South African business websites are built on.
It is free to use, highly flexible, and supported by a huge ecosystem of designers, developers and plugins. It powers everything from simple five-page business sites to large e-commerce stores and news platforms.
When a web designer says they build on WordPress, it means your site will run on this platform and you will manage your content through the WordPress dashboard. It is beginner-friendly once you know where things are.
6. Responsive Design:
What it is: A responsive website automatically adjusts its layout depending on the screen size it is being viewed on.
The same site looks and works correctly whether someone is on a desktop monitor, a tablet or a smartphone. Sections stack neatly, text resizes, buttons remain tappable. Nothing breaks or overflows off the screen.
Responsive design is not optional in 2026. The majority of South African internet users browse on mobile, and Google ranks mobile-friendly sites higher in search results.
7. Mobile-First:
What it is: Mobile-first means the website is designed with the mobile experience as the priority, rather than as an afterthought.
A responsive site adjusts to mobile. A mobile-first site is built for mobile from the ground up, then scaled up for larger screens. The difference matters in practice: mobile-first sites tend to be faster, cleaner and more intuitive on a phone.
If your customers are mostly finding you on their phones, which is increasingly likely, mobile-first design directly affects how many of them stay on your site long enough to get in touch.
8. Page Builder:
What it is: A page builder is a tool that lets you design the visual layout of your website by dragging and dropping elements into place, without touching any code.
Popular page builders for WordPress include Elementor and Beaver Builder. They give you visual control over how a page looks: where the headings go, how wide the columns are, what images appear where.
Page builders make it easier to update your site yourself after launch. They also speed up the design process, which is why a majority WordPress designers use them.
9. Plugin:
What it is: A plugin is a piece of software you add to WordPress to give your site extra functionality.
Plugins handle things like contact forms, SEO settings, security, speed optimisation, e-commerce, image galleries and dozens of other features. Instead of building every feature from scratch, a developer installs a plugin that handles it.
The key thing to understand as a business owner is that plugins need to be kept updated. Outdated plugins are one of the most common causes of WordPress security issues and site breakdowns.
10. Cache:
What it is: Cache is a saved version of your website that loads faster because it does not have to rebuild from scratch every time someone visits.
When a visitor opens your site, their browser or your server stores a temporary copy of certain elements. The next time the page is requested, it loads the saved version instead of generating everything fresh, which is significantly faster.
You might encounter cache when you update something on your site but the change does not seem to appear. Clearing the cache forces the site to load the latest version. It sounds technical but most caching plugins have a one-click clear option.
11. Metadata (Page Title and Meta Description):
What it is: Metadata is the information about your page that appears in search results rather than on the page itself.
When you search for something on Google, you see a blue clickable heading and a short paragraph beneath it before you visit the site. The blue heading is the page title. The paragraph is the meta description. Both are set in your CMS and both affect whether people choose to click on your result.
Good metadata is short, clear and relevant to what the page is actually about. It does not directly change your ranking but it does affect how many people click through to your site.
12. SEO:
What it is: SEO stands for search engine optimisation. It is the process of making your website easier for Google to find, understand and recommend to people searching for what you offer.
SEO covers a wide range of things: how your pages are structured, what words you use, how fast your site loads, whether other sites link to yours, and how well your content matches what people are actually searching for.
It is not a quick fix or a one-time task, but the basics are straightforward and the returns compound over time. We have written a full guide on “SEO for South African businesses” if you want to go deeper on this.
13. Landing Page:
What it is: A landing page is a standalone page designed to focus a visitor’s attention on one specific action, like filling in a form, making a purchase or requesting a quote.
Unlike a regular website page that has navigation and links to other sections, a landing page removes distractions and guides the visitor toward a single outcome. They are commonly used for advertising campaigns, product launches or service promotions.
If you have ever clicked on a Facebook or Google ad and landed on a page that looked slightly different from the main website, that was probably a landing page.
14. E-Commerce:
What it is: E-commerce simply means selling products or services online through your website.
An e-commerce site has a product catalogue, a shopping cart, a checkout process and a payment gateway. In South Africa, most business e-commerce sites are built on WooCommerce, which runs on top of WordPress.
E-commerce sites require more setup than standard websites because of the payment integration, shipping configuration and product management involved. They also need more ongoing maintenance to stay secure and functional.
15. DNS:
What it is: DNS stands for Domain Name System. It is the system that connects your domain name to your hosting server so visitors end up in the right place.
When someone types your web address into a browser, DNS translates that address into the specific location of your server. You never see this happening but it occurs every time someone visits your site.
DNS settings also control where your email is handled. If you have ever had to set up business email and been asked about MX records, that is part of DNS. Most designers and hosting providers handle this for you during setup, but it is useful to know what it refers to.
When a Quote Uses Terms You Do Not Recognise:
A good web designer will explain their work in plain language. If you receive a quote or brief that is full of terms you do not understand, it is completely reasonable to ask for clarification. Any designer worth working with will answer without making you feel like you should already know.
Use this guide as a reference point before or during those conversations. The more clearly you understand what is being proposed, the better the brief you can give, and the more accurate your quote will be.
If you are at the stage of planning a website and want to understand what the process actually involves, our “Websites and E-commerce page” covers how we work and what to expect. Or if you have specific questions, “get in touch” and we will walk you through it.
