What is a WordPress Plugin?

WordPress has become one of the most powerful, simplest, and widely used website and blogging Content Management Systems (or CMS). The compelling reason behind WordPress’s popularity is its powerful plugin architecture and template system. In this guide, you will also learn different methods to Install WordPress Plugins.

Nowadays, WordPress covers more than 33% of all the websites in the Internet world.

Let’s first grasp the basic concept behind the WordPress plugin and how it’s useful for web developers to quickly develop a website or blogging site.

Why WordPress Plugin?

As the name suggests, a Plug-in is a separately developed and tested software component that Plugs-Into an existing running application which in this case is a WordPress website or blog.

In computer software terminology, a plug-in is a software component that adds specific functionality to an existing computer application. When a program supports plug-ins, it enables customization. Plug-in acts like an add-on or extension that is installed on a program to extend its capabilities. For example, if you want to watch a video on a website, you need a plugin to play it because your browser doesn’t have the tools it needs.

WordPress plugins range from a small adding image to the sidebar to creating an e-commerce store.

In a nutshell, a WordPress plugin is a PHP-based script containing a set of functions that can be added to an already-developed WordPress website/blog. This can either extend the existing functionality or add new features to running a WordPress website.

All the WordPress plugins are written in PHP programming language and integrated seamlessly into a WordPress website.

WordPress provides a rich set of plugins from different third-party vendors for all categories, like SEO plugins, WordPress Plugin to Protect websites from spam comments, etc.

Here, is a complete list of WordPress plugins available for free download at the official WordPress plugin directory.


Main Applications of WordPress Plugin:

  • Separate source code from an application because of incompatible software licenses.
  • Enable third-party developers to develop abilities that extend an application.
  • Flexibility to easily add new features.
  • Reduce the size of an application.
  • Component re-usability – having a separate plugin for specific functionality.

WordPress Free vs Premium Plugins

WordPress offers plugins in two basic categories – free and premium (premium with minimal fees from third-party providers). These plugins allow users to customize functions and features enabling users to tailor their sites to their specific needs. For, the example you can extend or enable your website/blog to protect from spam comments Akismet
WordPress allows the plugins to be updated from time to time.

How does WordPress Plugins Work?

WordPress plugins once installed, can be activated, deactivated, or deleted from the WordPress website/blog.

Note that plugins are active across the different WordPress themes. For example, if you have changed your current WordPress theme, then still the WordPress plugins which were already activated will continue to work seamlessly.

WordPress plugins architecture works on the concept of hooking mechanism which allows developers to insert custom code into WordPress website.

What are WordPress hooks and types?

WordPress hooks are functions that can be executed at a particular point of time when a WordPress page is loaded. There are 2 types of hook functions – actions and filters. Action hooks are used to hook actions and filters are to hook filters.
