A WordPress website is a site built using the WordPress content management system (CMS), one of the most popular platforms for creating websites globally. WordPress is an open-source platform, meaning it’s free to use and customizable, making it accessible to anyone, from beginners to professional developers. Initially launched as a blogging platform, WordPress has evolved into a full-fledged CMS that powers over 40% of all websites on the internet, including blogs, business sites, e-commerce stores, portfolios, and more.
