WordPress is an open-source content management system (CMS) that enables users to create, manage and maintain digital content on websites. It is based on the PHP scripting language and uses a MySQL database to store data. Since its release in May 2003, it has become the world’s most widely used CMS and is used for everything from simple blogs to complex corporate websites and online shops.
The core features and architecture of WordPress
At its core, WordPress offers an intuitive user interface that allows users with varying levels of technical knowledge to publish content. The system’s modular architecture is extended by so-called plugins and themes. Plugins add specific functionalities, such as SEO optimisation, security features or e-commerce solutions like WooCommerce. Themes determine the visual appearance and layout of the website. This extensibility is a key factor in WordPress’s flexibility and adaptability to virtually any project.
- User-friendliness: Easy installation and operation via a clear and intuitive dashboard.
- Extensibility: Thousands of free and paid plugins and themes are available.
- Open source: Continuous development by a global community.
- Versatility: Suitable for blogs, portfolios, corporate websites, forums and online shops.
WordPress in professional use and its relevance
For agencies and developers, WordPress offers a robust foundation for bespoke web projects. Thanks to the wide availability of documentation, developer resources and an active community, tailor-made solutions can be implemented efficiently. The system’s scalability makes it possible to meet requirements ranging from small landing pages to large, high-traffic portals. As of September 2025, WordPress powers 60.7% of all websites that use a recognised content management system. When considering all websites on the internet, including those without a recognised CMS, the market share stands at 44.2 per cent (as of April 2025). The regular release of security updates and new features ensures the platform’s future viability and the stability of the websites built on it.
