WordPress Plugins Explained

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

Add New Functionality To Your Website With PluginsOne of the main benefits of WordPress is the ability to quickly and easily expand your WP web site’s functionality using inexpensive (and often 100% free) software called ’plugins’.

What Are Plugins?

Like most people, you probably own a device like a mobile phone. What happens when you want access to something new on your device like a new application, software or a tool?

Why, simple … you download and install an app!

An app is a little software application that is really easy to install and immediately integrates new features and functionality into a smart device.

(Just as you will find social sharing apps for smart devices …)

A WordPress plugin is quite similar to an app. You install and activate a software application that provides new functionality to your WP site …

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

Generally, if you plan to expand the functionality of an already-built web site, additional cost is involved. Depending on the complexity of the feature or enhancement, this cost can be significant, particularly if website developers need to add new code or modify code or install programs to integrate into your existing site.

This also applies when developing a new website. Business owners often invest up-front in features or customizations they probably will never need.

To save money and keep costs low, we suggest a sustainable strategy when setting up a website and WP plugins are ideal for helping you achieve this.

Wouldn’t it be great if you could:

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

2) As the need becomes apparent, install new applications with a couple of mouse clicks directly from your WordPress administration panel, giving your website or blog an entirely new range of practical functionality, and …

3) Cost not a single cent more to install on your website?

Well, this is exactly what WP plugins allow you to do!

Benefits & Advantages Of Plugins

I started this article by comparing WP plugins with apps. Just like many apps are free to download and some apps may cost a little money, so do plugins.

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

Plugins that you buy are referred to as Premium plugins. The good news, is that when you compare it to the price of hiring a professional web developer to add similar features and functionality on your site, most Premium plugins are typically very inexpensive.

Also, because WordPress distributes its software as an Open Source application, anybody can create, edit and customize any portion of the code. This has enabled many professional web development companies to create more tools that add new functionality to the WordPress platform than you can probably imagine.

  • WP plugins let you get started with a basic site and then add new features and enhancements to your site if necessary.
  • Plugins allow you to add almost unlimited features to any site easily and inexpensively.
  • Plugins give your web site virtually unlimited expanding capabilities.
  • Plugins allow ”non-techies” to own a site that they can self-manage.
  • Most plugins normally work “right out of the box” and only require installation and activation to give your web site new capabilities, enhancements and functionality.
  • Some plugins can be slightly more advanced and could require some initial configuring.

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

Just like themes, thousands of great plugins are currently available to WP users … often at no cost!

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

Useful Things You Should Know About WordPress Plugins

  • There are many WordPress plugins available. Be careful of overloading your site with too many plugins, as this can begin to affect your website’s resources and site loading times. It can also create more maintenance work for you as a consequence of potential conflicts and errors.
  • Install only the plugins you really plan to use. Delete any plugins you don’t use from your site, as these use resources.
  • Many free plugins normally receive little to no support from the plugin developer. When choosing premium WP plugins, ensure that you do a little research first to see what kind of reputation the developer has when it comes to providing support, upgrades, new features, etc. Be sure to check some of our WordPress plugin recommendations for more information.
  • If you see that a plugin has not been updated for a very long time (e.g. two years), then think twice before using it. WordPress is updated frequently and outdated WP plugins can cause errors.
  • Always keep all plugins up-to-date. Outdated plugins not only can create errors, they may also contain vulnerabilities that could be exploited by hackers and malware.

A Guide To WP Plugins

As you can see, WP plugins are an important aspect of WordPress and contribute to making WordPress the most downloaded content management solution in the world. Plugins also provide WordPress users with an easy, simple and inexpensive way to expand without having to spend thousands of dollars on outsourced web development costs.

One last thing regarding WP plugins:

If there is any feature or functionality you need for your web site, you can be sure that a someone has probably already authored one that will do just what you want it to do, and that this plugin will either be available at no cost, or if it’s a premium plugin, that the price to buy it will be reasonable.

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

(Whatever you need done, there’s a WordPress plugin for that!)

And, if by chance this plugin does not exist, then a custom plugin that does precisely what you would like it to do can probably be written for you at a reasonable cost.

Hopefully, now you have a better understanding of WP plugins – what plugins are and how they can help improve your business blog. See our related posts to learn about more popular plugins that we recommend using.
