WordPress Plugins Explained

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

WP Plugins - Expand Your Web Site's CapabilitiesOne of the most useful benefits of WordPress is the ability to quickly and easily enhance your WordPress site’s functionality using plugins.

What Are WP Plugins?

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

You download and install an app!

An app is a little software application that is really simple and easy to install and instantly integrates new features into your mobile phone.

A WP plugin is very much like an app. You simply download and install a software application that adds new functionality to your WordPress website …

(… you can also find social sharing plugins for WP sites!)

Almost always, if you plan to expand the functionality of an already-built site, additional cost is involved. Depending on the complexity of the feature or enhancements, things can get fairly expensive, especially if it involves website development.

This is also applicable when setting up a new website. Companies often invest up-front for added features or customizations they may probably never need.

As part of sound strategic business planning, we recommend a modular strategy when growing a web site and WordPress plugins are ideal for helping you achieve this.

Imagine being able to:

1) Start simply and inexpensively. Get your business website up and running quickly, then …

2) As you need more features, add new applications with only a few clicks of the mouse directly from within your WP admin area, giving your website or blog a whole new range of useful functionality, and …

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

Well, this is precisely what a WP plugin enables you to do!

Plugins – Benefits & Advantages

Earlier, we compared plugins with apps. In the same way that some apps are free to download and some may cost a little bit of money, the same is true of plugins.

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

Plugins that you purchase are called ’Premium’ plugins. The good news, is that when compared to the price of paying for professional web development services to get similar features and functionality on your site, most Premium plugins cost very little.

Also, as WordPress makes its code publicly available, anybody can create, modify and customize any portion of the code. This has allowed thousands of professional web developers to enhance the core WordPress software application.

  • WP plugins allow you to start simply with just a basic yet professional web site and then add new features and enhancements to your site if necessary.
  • WP plugins let you add practically endless features to your web site quickly, easily and inexpensively.
  • Plugins give your web site practically endless expanding capabilities.
  • Plugins allow business owners to have 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 website new capabilities and functionality.
  • Some plugins offer more advanced features and may need some configuration.

Plugins – Useful Information

  • There are lots of great WordPress plugins to choose from. Be careful not to overload your site with an excessive amount of plugins, as this can start to affect your website’s performance and site loading speed. It also means more maintenance work for you resulting from potential conflicts.
  • Install only the plugins that you really need to use. Delete any plugins you don’t need from your site, as these use resources.
  • Many free plugins typically receive very little to no support from the plugin developer. When considering premium plugins, we recommend that you do a little research first to understand what kind of reputation the plugin developer has when it comes to offering support, updates, new features, etc. Be sure to check some of the plugin reviews we provide here for more expert 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 carefully before installing it. WordPress is updated regularly and outdated WordPress plugins can cause issues.
  • Always update your plugins. Outdated plugins not only can cause issues, they may also contain security vulnerabilities that can be exploited by hackers and malware.

One last thing regarding WP plugins:

Whatever functionality you want for your web site, you can be sure that a someone has probably already created one that will do what you want it to do, and that this plugin will either be available for FREE, or if it’s a paid plugin, that it will be surprisingly inexpensive.
