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 - The Easy Way To Enhance Your Blog's Features And FunctionalityOne of the main benefits of the WordPress software is the ability to easily increase your WP site’s functionality using applications called plugins.

Understanding Plugins

Like most people, you most likely use a device like a smart phone. What happens when you want access to something new on your device like a new software or a new business tool?

You download and install an app!

An app is a little piece of software that is easy to install and adds new functionality to any mobile phone.

(Just like you will find social sharing apps for mobile phones …)

A WordPress plugin is like an app. You install a little piece of software that provides new functionality to your WordPress site …

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

Generally, adding new features to an already-built web site involves additional cost. Depending on the complexity of the feature or enhancement, this could get fairly expensive, particularly if it involves modifying code.

This also applies to developing a website or business blog. Companies will often invest in components they probably will never need.

As part of sound strategic business planning, we suggest using a sustainable approach when growing a digital presence presence and WP plugins are ideal for helping you achieve this.

Wouldn’t it be great if you could:

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

2) As you need more features, just install new applications with only a couple of mouse clicks that integrate seamlessly with your current website, giving your web site a whole new range of possibilities, and also …

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

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

WP Plugins – Benefits And Advantages

We started this article by comparing WP plugins with smartphone apps. In a similar way that many apps are free to download and some cost a little money, the same is true for WordPress plugins.

In fact, loads of useful plugins are freely available for WP users.

Plugins that you buy are referred to as Premium plugins. The good news, is that when compared to the cost of paying for web development services to add similar functionality on your site, most Premium plugins cost very little.

Also, as WordPress distributes its software as an Open Source application, anybody can create, rewrite and customize any portion of the code. This has enabled thousands of third-party web development companies to create more tools that “plug into” WordPress than you can possibly imagine.

  • Plugins let you start simply with just a basic website and then add new features and enhancements to your site only if necessary.
  • Plugins allow you to add almost endless functionality to your web site quickly and quite inexpensively.
  • Plugins give your site virtually unlimited expansion capabilities.
  • WP plugins allow business owners to have a digital presence that they can manage themselves.
  • Most plugins will typically work “right out of the box” and only require installation and activation to provide your website with immediate capabilities and enhancements.
  • Some plugins offer more extensive features and may need some configuration.

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

Like many themes, tens of thousands of great WordPress plugins are available for WordPress users … for FREE!

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

Useful Things You Should Know About Plugins

  • There are many great WordPress plugins to choose from. Be careful not to overload your site with too many plugins, as this will start to affect your website’s performance and page loading speed. It also means more maintenance issues for you resulting from potential conflicts and errors.
  • Install only the plugins you really need. Delete inactive plugins from your site, as these utilize resources.
  • Many free plugins normally receive little to no support from the plugin author. When considering paid plugins, we recommend that you check some reviews online and see what kind of reputation the plugin developer has when it comes to providing support, upgrades, new improvements, etc. Be sure to check our plugin reviews for additional helpful information.
  • If you see that a plugin has not been updated for a while (e.g. two years), then think twice before installing it. WordPress updates frequently and older plugins that have not been updated can create errors.
  • Ensure that you always update your plugins to their latest version. Older plugins not only can create problems, they could also have security vulnerabilities that can be exploited by hackers and malicious software.

A Useful Guide To WP Plugins

One last thing on the subject of plugins:

If there is any feature or functionality you want for your web site, you can guarantee that a plugin probably exists 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 cost to buy it will be quite affordable.

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

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