WordPress

WordPress is an open-source content management system (CMS) and the world's most used website platform, powering over 40% of all websites – from simple blogs to complex corporate sites.

WordPress has fundamentally changed how websites are built. What started in 2003 as simple blogging software has become the world's dominant content management system. Over 40% of all websites run on WordPress – from personal blogs and business sites to online shops and news portals. The combination of ease of use, a huge plugin ecosystem and an active community makes WordPress the most accessible platform for creating websites.

What is WordPress?

WordPress is an open-source CMS written in PHP and using MySQL or MariaDB. It was founded in 2003 by Matt Mullenweg and Mike Little and is developed by the WordPress Foundation and Automattic. WordPress comes in two forms: WordPress.org (self-hosted open-source software) and WordPress.com (hosted service by Automattic). The platform provides the Gutenberg block editor for visual content creation, a theme system for design and a plugin system with over 60,000 free plugins in the official directory. WordPress supports custom post types, taxonomies and REST APIs for headless CMS use. WooCommerce, the most popular WordPress plugin, adds full e-commerce. A market share of over 40% makes WordPress by far the most used CMS worldwide.

How does WordPress work?

WordPress is installed on a web server with PHP and MySQL and managed via a browser-based backend (dashboard). Editors create content with the visual Gutenberg block editor, which provides blocks for text, images, video, buttons and layouts. Themes define the design and layout and can be customized via the Customizer or Full Site Editor. Plugins add functionality – from contact forms and SEO tools to e-commerce. WordPress generates pages dynamically from the database and uses caching plugins for performance. The REST API allows external applications to access WordPress content, making WordPress usable as a headless CMS.

Practical Examples

A mid-size company runs its corporate website on WordPress and uses the Full Site Editor to adapt the entire design to its identity without coding.

An online retailer uses WordPress with WooCommerce to run a webshop with over 5,000 products, payment integrations and automated shipping.

A news portal uses WordPress Multisite to manage several regional news sites centrally with shared users and theme configuration.

A blogger monetizes their WordPress site with plugins for member areas, newsletter integration and affiliate marketing.

An agency builds a headless WordPress setup where WordPress serves as the content backend and a Next.js frontend fetches content via the REST API.

Typical Use Cases

Corporate websites with professional design that non-technical editors can maintain

Blogs and content portals with regular publishing, categories and SEO optimization

E-commerce shops with WooCommerce for small to medium catalogues and flexible payment and shipping

Portfolios and landing pages implemented quickly and cost-effectively with ready-made themes

Headless CMS scenarios where WordPress is the content backend with a modern frontend

Advantages and Disadvantages

Advantages

Easiest to use: Intuitive interface that allows content management without technical knowledge
Huge ecosystem: Over 60,000 plugins and thousands of themes for almost every use case
Low entry cost: WordPress itself is free and cheap hosting is available from a few euros per month
Large community: Global community with extensive documentation, forums, meetups and WordCamps
SEO-friendly: Plugins like Yoast SEO and Rank Math add comprehensive SEO features in the dashboard

Disadvantages

Security risk: Widespread use makes WordPress a frequent target – regular updates and security plugins are essential
Performance: Without caching and optimization WordPress can be slow under high traffic
Plugin quality: Not all 60,000 plugins are well maintained – outdated or poorly coded plugins can cause security and performance issues
Limits at high complexity: For very complex applications or enterprise requirements WordPress can reach its limits

Frequently Asked Questions about WordPress

What is the difference between WordPress.org and WordPress.com?

WordPress.org is the free open-source software you install on your own hosting and can customize freely. WordPress.com is a hosted service by Automattic that offers WordPress as a ready-made product. WordPress.org gives full control and flexibility but requires your own hosting and maintenance. WordPress.com is easier to set up but the free plan limits features and customization.

Is WordPress secure?

WordPress itself receives regular security updates. Most security issues come from outdated plugins, weak passwords or insufficient hosting hardening. With regular updates, security plugins (e.g. Wordfence), two-factor authentication and a good host WordPress can be run very securely. It is important to use only plugins from trusted sources.

Is WordPress suitable for large websites?

Yes. WordPress scales well – sites like TechCrunch, BBC America and Time.com use WordPress. For large sites capable hosting (managed WordPress hosting), caching (e.g. WP Rocket, Varnish), a CDN and careful plugin choice are important. For very complex enterprise needs with extensive permissions and multilingual content TYPO3 or a specialized CMS may be the better choice.
