At its core, WordPress is the simplest, most popular way to create your own website or blog. In fact, WordPress powers over 43.3% of all the websites on the Internet. Yes – more than one in four websites that you visit are likely powered by WordPress.
On a slightly more technical level, WordPress is an open-source content management system licensed under GPLv2, which means that anyone can use or modify the WordPress software for free. A content management system is basically a tool that makes it easy to manage important aspects of your website – like content – without needing to know anything about programming.
The end result is that WordPress makes building a website accessible to anyone – even people who aren’t developers.
