WordPress

WordPress is an open-source content management system (CMS) used to create, manage, and publish websites without needing to build everything from scratch.

It provides tools for managing pages, blog posts, images, menus, users, and other website content. Its functionality and appearance can be extended through themes and plugins, making it suitable for everything from blogs and business websites to online shops and large content-driven sites.

There are two commonly confused services:

  • WordPress.org — the open-source WordPress software that you can install on your own web hosting.
  • WordPress.com — a commercial hosted service built around WordPress.

In one sentence: WordPress is a website publishing and content management platform that allows users to build and maintain websites through an administrative interface.

Every plugin you install on your wordpress site is code running on your server with the same access as WordPress itself. A single abandoned or poorly maintained plugin can open your site to attackers, slow page loads, or break after a core update. With over 60,000 free plugins listed on WordPress.org, the challenge is not finding plugins; it is filtering them. This guide gives you a repeatable evaluation method built on six concrete signals of plugin health.
