Sometimes, website developers wish to make things easier for the user or implement new functionality to their website in order to enhance usability, improve website performance, or upgrade user experience.

What do plugins do and why do we need them

The same way we can add an app to our smartphone in order to turn it into a compass or a flashlight when we launch the app, we add plugins to add more value to our web presence. In essence, plugins are just pieces of code that we can implement in order to change a certain aspect of a website’s appearance or performance.

There are so many different types of plugins built for all sorts of purposes. WordPress plugin repository currently includes more than 55 thousand different plugins, some of which count millions of downloads by users that required improvements in the field of:

  • Safety
  • Performance
  • Visuals
  • SEO
  • Social Media Integration

This plugin can optimize your keywords use, rate content readability; as well as optimize your images.


Loading speed is one of the major issues that influence the performance of your website, which is of utmost importance for the user experience. WP Super Cache is a plugin that creates a static HTML page which the web server distributes to visitors instead of loading the content live every time a user decides to visit your page.

WordPress plugins such as Regenerate Thumbnails can help you improve the look of your thumbnails or images that can lose the initial size when you change existing WP theme with a new one that uses different image size for featured media content.


It doesn’t matter if you run a business or use WP as a blogging platform the security of your content is essential. There are different ways to keep your website protected; you can automatically backup your data, add login protection, or even install plugins that keep you safe from various forms of online attacks. Since backup is already available without the use of plugins, it’s best to avoid adding these types of software, simply to make your page lighter. On the other hand, plugins like All in One WP Security & Firewall provide comprehensive protection from all sorts of attacks and hassles.


Sharing your content across multiple social media platforms allows you to extend your reach and get more followers, which is what every site owner aims for. There are a series of plugins that allow us to install all sorts of social media share buttons. Easy Social Sharing is one of those plugins, allowing us to add share buttons, buttons that link to our social media profiles, or simply include mail subscription forms.


Some plugins can provide a series of different functions, usually correlated in some way, WordPress developers created the official WP Jetpack plugin, which carries all sorts of features that most basic users would require. Nevertheless, most plugins bring a single change to your website, thus preventing unnecessary waste of resources.


 How do WordPress plugins work

There are two ways in which a plugin can change your website:

Frontend changes

This includes changes that user can also visually notice and interact with, like a weather forecast plugin or google maps plugin.

Let’s say you want to allow your visitors to post content on your web page, or register to an event that you organize. Installing WP User Frontend Pro plugin allows your visitors to seamlessly interact with your page by displaying a customizable form that people can fill in depending on what the form allows them to do (post images, text files, submit event registration, etc.)


Backend changes

Plugins that change performance stats or improve SEO of your website but don’t display any visual effect that user could see or interact with, belong in this group.

One good example of backend change that we can introduce to our website through plugins is Featured Galleries. The plugin handles the administrative interface for creation of features galleries using a simple drag and drop functionality that allows you to insert multiple images instead of doing it one by one.
