WordPress Plugins Explained

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

WordPress Plugins - Extending Your Website's FeaturesOne of the main features of the WordPress software is that you can quickly and easily increase your WP website or blog’s functionality using plugins.

Understanding Plugins

No doubt, you most likely have a mobile phone. What happens when you want to access something new on your phone like a new application, software or a business productivity tool?

You download and install an app!

An app is a little software application that is simple and easy to install and integrates new functionality into your smart phone.

(Just like there are social sharing apps for smart devices …)

A WordPress plugin is similar to an app. You install a software application that provides new functionality to your website …

(… you can also find social sharing plugins for WordPress users!)

Almost always, if you need to expand the functionality of an existing web site, additional cost is involved. Depending on how complex the feature or enhancement is, this could become fairly expensive, especially if website developers have to add new code or edit templates or develop scripts that integrate with your existing site.

This also applies to creating a website. Organizations sometimes invest money up front for bells and whistles they probably will never need.

For this reason, we recommend a modular strategy to setting up a website and WordPress plugins are ideal for helping you achieve this.

Imagine being able to:

1) Start simply and inexpensively. Get a web site up and running quickly, then …

2) As you need more features and functionality, you can install new applications with a few mouse clicks directly from your admin section, giving your website a completely new range of features and functionality, and …

3) Cost not a single dollar extra to download and install on your web site?

Well, that’s exactly what a WP plugin lets you do!

Plugins – Benefits And Advantages

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

In fact, thousands of plugins are available at no cost to users.

WordPress plugins that you have to buy are called “Premium” plugins. The good news, is that when compared to the cost of hiring a professional web developer to get the same features and functionality on your site, most Premium (i.e. paid) plugins are priced quite cheaply.

Also, because WordPress makes its source code publicly available, anybody can create, edit and customize any portion of the code. This has allowed thousands of third-party software development professionals to build more new applications that “plug into” the WordPress application than you can possibly imagine.

  • Plugins let you start off with a basic site and then add new features and enhancements to your site when necessary.
  • Plugins let you add practically endless functionality to your web presence easily and cheaply.
  • WordPress plugins give you virtually endless expanding capabilities.
  • WordPress plugins allow ”non-techies” to own a website that they can self-manage.
  • Most plugins normally work “right out of the box” and only require installation and activation to give your site instant new capabilities, enhancements and functionality.
  • Some plugins offer more advanced options and may need some configuring.

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

Just like themes, thousands of WP plugins are currently available for WordPress users … and many of these great plugins are 100% FREE!

You can download thousands of plugins from the Free WordPress Plugin Repository

Plugins – Additional Tips

  • There are lots of great plugins available. Be careful not to overload your site with an excessive amount of plugins, as this can invariably affect your site’s resources and site loading speed. It can also create more maintenance work for you as a consequence of potential conflicts and errors.
  • Only keep the plugins you really need to use. Delete inactive plugins from your site, as these utilize server resources.
  • Many free plugins often receive very little to no support from the plugin developer. When considering paid plugins, make sure you check some reviews online and see what kind of reputation the plugin developer has when it comes to offering support, upgrades, new improvements, etc. Be sure to check some of our plugin recommendations for more information.
  • If you see that an unsupported plugin has not been updated for a while (e.g. two or more years), then think twice before installing it. The WordPress platform updates often and older plugins that have not been updated can create conflicts.
  • Always update your plugins. Outdated plugin not only can cause conflicts, they may also have vulnerabilities that can be exploited by hackers and malware.

As you can see, plugins are an integral part of WordPress and contribute to making WordPress the most popular CMS available. Plugins also provide WordPress users with easy, simple and inexpensive ways to add new features to their website without having to spend thousands of dollars on outsourced web development.

One last thing about plugins:

If there is any functionality you need for your website, you can guarantee that a someone has probably already authored one that will do exactly what you want, and that this plugin will either be available at no cost, or if it’s a premium plugin, that the cost will be surprisingly reasonable.

Whatever you need done, there's a WordPress plugin for that!
