In its simplest form, WordPress is a well known and easy-to-use method of building a website or blog. It has grown in popularity over the years so much that it is now accountable for more than 30% of total websites today. It’s possible that one out of four sites you’ve visited are powered by WordPress.
On a more technical note, the platform is a content management system (CMS) that is open source, meaning that anyone is free to change it as they please. A CMS is pretty much a tool that lets you manage the essential parts of a website – such as its content – without the need to be an expert in programming languages.
This is one of the main reasons why WordPress is a favoured CMS for those who aren’t website developers.
