WordPress Plugins Explained

This tutorial explains what WordPress plugins are, how plugins work and how plugins help WordPress users extend their website’s functionality. 

Using WP Plugins Extend Your Web Site's FunctionalityOne of the most useful advantages of using WordPress is the ability to quickly and easily enhance your WordPress web site’s functionality using plugins.

What Are Plugins?

No doubt, you most likely own a smart phone. What do you do when you would like to access something new on your phone like a new game or business productivity tool?

You download and install an app!

An app is a software that is really simple and easy to install and instantly integrates new features and functionality into a mobile device.

(Just like you will find social sharing apps …)

A WP plugin is like an app. You download and install an application that adds new functionality to your website or blog …

(… there are also social sharing plugins for WP sites!)

Generally, expanding the functionality of an already-built website involves additional cost. Depending on how complex the feature or enhancement is, this cost can be fairly significant, especially if it requires website development.

This also applies when creating a new website. Many business owners will often pay up front for features they probably will never need.

For sound, strategic business planning reasons, we recommend a sustainable approach when developing a web presence presence and WP plugins are ideal for doing this.

Imagine if you could:

1) Start simply and inexpensively. Get your web site up and running fast, then …

2) As more features or functionality become necessary, add new applications with just a couple of clicks of the mouse that integrate seamlessly with your existing web site, giving your website or blog an entirely new and expanded range of useful capabilities, and …

3) Cost not one dollar extra to install on your web site?

Well, that’s precisely what a WP plugin allows you to do!

Plugins – Benefits And Advantages

Earlier, we compared WordPress plugins with ’apps’. In a similar way that some apps are free to download and some may cost a little money, so do WordPress plugins.

In fact, thousands of plugins can be downloaded and installed on your sites.

Plugins that you purchase are referred to as Premium plugins. The good news, is that when compared to the price of hiring a professional web developer to get similar functionality on your site, most Premium (i.e. paid) plugins cost very little.

Also, since WordPress is an Open Source application, anybody can create, rewrite and customize any portion of the code. This has allowed thousands of third-party software development companies to build more tools that expand the WordPress software than you can imagine.

  • Plugins let you get started with just a basic yet professional online business presence and then add new features and enhancements to your site if required.
  • WP plugins let you add practically endless functionality to any site quickly and really inexpensively.
  • WordPress plugins give you practically unlimited expanding capabilities.
  • Plugins allow business owners to own a website that they can self-manage.
  • Most plugins typically work “right out of the box” and only require to be installed and activated to provide your site with new capabilities and enhancements.
  • Some plugins can be slightly more complex and may require some initial configuring.

Plugins – Powerful, Flexible … And (Many Of Them Are) 100% FREE!

Like many themes, loads of plugins are currently available to WP users … and many of these great plugins are 100% FREE!

You can view and download thousands of plugins from the Free WordPress Plugin Directory

WP Plugins – Some Useful Tips

  • There are loads of plugins to choose from. Be careful of overloading your server with an excessive amount of plugins, as this will inevitably affect your website’s performance and page loading speed. It can also mean more maintenance work for you as a result of possible errors.
  • Only keep those plugins that you really need to use. Delete any plugins you don’t need from your site, as these use server resources.
  • Many free plugins normally come with very little to no support from the plugin author. When considering paid plugins, ensure that you do a little research first to understand what kind of reputation the plugin developer has when it comes to providing support, updates, new features, etc. Be sure to check some of our WordPress plugin reviews for more information.
  • If you see that an unsupported plugin has not been updated for a very long time (e.g. two or more years), then think twice before installing it on your site. The WordPress platform changes regularly and older plugins that have not been updated can create issues.
  • Always upgrade your plugins. Older plugin not only can create errors and conflicts, they could also have vulnerabilities that can be exploited by hackers and malicious users.
