Before content management systems existed, building a website meant writing raw HTML code for every single page. Today, a CMS allows anyone — without coding knowledge — to create, edit and publish web content through a user-friendly interface. This is how the majority of websites on the internet are built.
How a CMS Works
A traditional CMS has three main components:
- Database — Stores all your content (articles, pages, user data) in a structured format (usually MySQL).
- Backend (Admin Panel) — The interface where you write, edit and organise content.
- Frontend (Theme/Template) — The design layer that takes content from the database and presents it to visitors.
When someone visits your site, the CMS retrieves content from the database, applies your theme and generates the HTML that's sent to the browser — all in milliseconds.
Popular CMS Platforms
WordPress
Powers approximately 43% of all websites on the internet. Open-source, free to download, with tens of thousands of themes and plugins. Best for blogs, business sites and content-heavy websites.
Shopify
A hosted e-commerce CMS — everything is managed for you. Ideal for online stores, especially those just starting out.
Drupal
Highly flexible and powerful, but with a steeper learning curve. Used by large organisations, government sites and complex applications.
Joomla
A middle ground between WordPress and Drupal. More flexible than WordPress, easier than Drupal. Has a smaller community and fewer plugins.
Headless CMS
A modern approach where the CMS manages content only (no frontend). Content is delivered via API to any frontend — a website, mobile app, smart TV or any digital channel. Examples: Contentful, Strapi, Sanity.
CMS vs Website Builders
CMS (e.g. WordPress) is installed on hosting you control. More flexible, more complex, requires maintenance.
Website builders (e.g. Wix, Squarespace) are all-in-one hosted solutions. Easier to use, less flexible, you don't own the infrastructure.
Do You Need a CMS?

- Multiple pages that change regularly → Yes
- Multiple authors or contributors → Yes
- A blog or news section → Yes
- A single landing page that rarely changes → Possibly not
