Chapter 9: What are WordPress Plugins? How to install WordPress Plugins?

As this guide is for beginners who are not having any coding or programming experience, so one question is running in your mind that what does the Plugin actually mean?

Plugins are the most important part of the WordPress environment, and they are very essential for building great websites by using WordPress.

What Are WordPress Plugins?

WordPress’s plugins are just like apps in your smartphones that allow you to enhance and add entirely new features to your site. And also extend the functionality to your WordPress website. They are usually free to the public.

There are more than 48,000 free plugins are available on the WordPress.org plugin directory. Also there are thousands of premium WordPress plugins that are sold by individual developers and companies are also available.


There are too many WordPress plugins are available like to improve SEO, add contact forms, Boost Performance, social media buttons, create galleries, and so on. Plugin can be seen in the sidebar of your dashboard as it added an image to it of that particular plugin.More feature rich plugins can have their own addon plugins to extend them just like you would extend WordPress.

How WordPress Plugins Work?

WordPress is written in such a manner so that other developers can upload their personal code into it. The WordPress plugin API gives a strong set of hooks and filters which allow developers to modify current WordPress functionality or add new functionality.

WordPress also permits developers to store data in the WordPress database. Plugins can make use of WordPress content material types, taxonomies, and custom fields which permits users to store different sorts of content material not just posts and pages.

Each WordPress plugin installed in your website online is registered in your WordPress database. You can activate and deactivate them at any time you wish.


Upon every visit, WordPress connects to the database, loads the middle software, and then loads your active plugins. All this code is processed for your server and then sent to the user’s browser.

How to Find WordPress Plugins and Install them?

You can find free WordPress plugins by visiting WordPress.org plugin directory or you can also find them directly from your WordPress admin area.

  • First go to the Plugins option on the left side of the dashboard.
  • Second Click on Add New
  • Search Plugins in the search box (top right corner) by typing the plugin name or functionality you want to add.

Searching for plugins from the WordPress admin area

WordPress will search the plugin listing and display the available plugins in a list. Check the review of the results, and click on the Install now button next to the plugin you want to install.

Reviewing and putting in plugin from search results

However, search results in the WordPress admin area aren’t usually beneficial because they may be limited to free plugins only. Most beginners find it difficult to determine which plugin is high-quality for the job.

How to check Plugin Updates?

Plugin builders or developers update their plugins occasionally, and those updates will be visible to you on your website’s Plugins page. To discover any plugin installed on your site that need to be updated:

  • First click the “Plugins” hyperlink in the left nav of your website’s dashboard.
  • Then look down the listing of installed plugins for any that encompass a line reading “There is a new version…”
  • Click the “View version…” hyperlink in that note to view information about the plugin’s update.
