Everything You Need to Know about WordPress Plugins

A WordPress plugin, in a nutshell, refers to an add-on “plugged in” to your WordPress site to either add new features or extend existing functionalities. It allows users to upgrade and expand the function of your WordPress site without touching a bit of code.

WordPress plugins undoubtedly are one of the most celebrated tech trends in the WordPress community. They are exceptionally versatile, from adding a small tweak or bringing dramatic changes to your site. Think of anything you need for your site and WordPress plugins will meet them all.

For example, you can:

  • Customize the look of your website
  • Boost your site performance
  • Optimize your images
  • Turn your site into an online store
  • Create contact forms
  • Enhance SEO
  • Add a Learning Management System to your site, and tons more.

History of WordPress Plugins

WordPress plugins were first brought to life on May 22, 2004, with the third release of WordPress version 1.2 named Mingus. Before the release, users had to use their “hacks” to extend or add new features to WordPress. These hacks were a set of files, including instructions on what core needed to edit and where to insert code.

In fact, building a plugin system was the idea of a WordPress contributor Ryan Boren. Developers could make use of the hooks and filters in the WordPress core to “hook into” the site and run their custom codes. This system provided two significant benefits:

    • Developers were free from editing WordPress core files. This allowed having WordPress updated without losing customizations.
    • It saved non-tech-savvy users’ effort from editing files, copying or pasting code. Everything would be more convenient by just activating or deactivating a plugin.

How do Plugins Work?

“Not to touch the WordPress core” is always a cardinal rule of WordPress development. This is because WordPress overwrites their core files with each update. As a result, any process of adding or extending its functionality must be done using plugins, rather than modifying the core files.

Plugins use a set of filters and hooks offered by the WordPress API to hook into the source code and integrate their functions. Each time you log in, WordPress connects to the database, then respectively loads the core files and active plugins. Any plugin installed is stored on your WordPress database, therefore, you can activate or deactivate them as you wish.

Where to Find Your WordPress Plugins

There are several places to look for plugins, depending on whether you want free or premium ones.

The best place to search for your free plugins is at the WordPress plugin directory of wordpress.org. This massive plugin repository also includes customer ratings and reviews, along with the number of active installations for each plugin.

As wordpress.org mainly offers free plugins, there are some kinds of premium ones you can’t find here. For premium ones, we suggest you visit CodeCanyon and WPMU DEV.

CodeCanyon proves one of the largest repositories of premium WordPress plugins, containing up to 7,200 available plugins in its stock. All detailed information about plugins, as well as user reviews and ratings are also provided.

Another abundant source of quality WordPress plugins is WPMU DEV. It offers a wide range of plugins, from ad managers, redirect, analytics to security, design, social media integration, and so on. Its unique style in offering products sets this site apart from most directories. After paying a membership costing $49, you’ll have permission to access all plugins, which can be installed on unlimited sites.

Asides from CodeCanyon and WPMU DEV, some developers choose to sell their premium plugins only on their websites, i.e, Password Protect WordPress Pro and Prevent Direct Access Gold. Therefore, using Google is always a helpful way to help you find out the right plugins for your site.

Use WordPress Plugins at WordPress.com – Can or Cannot?

Normally, users from self-hosted WordPress – WordPress.org can freely install and utilize plugins. However, the same scenario doesn’t apply to WordPress.com users.

Most of the time, you’re unable to install or use any plugins if you’re using wordpress.com. However, WordPress recently changes its policies. Third-party plugins can be installed by specific users who upgrade to WordPress.com Business Plan, which costs $25/month.

You’ve armed yourself with overall plugin knowledge. It’s time to discover the juiciest WordPress plugin statistics and facts 2021.
