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 - The Easy Way To Enhance Your Website's CapabilityOne of the main benefits of choosing WordPress is that you can easily expand your WP site’s functionality using plugins.

Understanding Plugins

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

You download and install an app!

An app is a software that is really easy to install and instantly adds new features and functionality to any smart phone.

(Just as there are social sharing apps …)

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

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

Typically, expanding the functionality of a web site involves additional cost. Depending on the complexity of the feature or enhancement, this cost can be fairly significant, particularly if it involves website development.

This also applies when setting up a website or business blog. Companies tend to pay money in advance for added components they probably will never need.

For sound, strategic business planning reasons, we suggest using a sustainable strategy to growing your web presence presence and WP plugins are ideal for doing this.

Imagine if you could:

1) Start simply with minimal expense involved. Get a web presence up and running quickly, then …

2) As you need more features and functionality, simply install new applications with just a few clicks of the mouse directly from within your WordPress dashboard section, to give your website a whole new and expanded range of capabilities and functionality, and …

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

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

Benefits And Advantages Of Using WordPress Plugins

We started this blog post by comparing WordPress plugins with smartphone apps. Just like some apps are free to download and some may cost a little bit of money, the same is true of WP plugins.

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

WP plugins that you have to buy are referred to as ’Premium’ plugins. The good news, is that when you compare the cost of purchasing a Premium plugin to the price of hiring a professional web developer to get similar features and functionality on your site, most Premium (i.e. paid) plugins are generally quite inexpensive.

Also, since WordPress is an Open Source application, anyone can create, modify and customize any portion of the code. This has enabled thousands of professional software development professionals to build more new plugins that “plug into” WordPress than you can probably imagine.

  • Plugins allow you to get started with only a basic site and then expand only as required.
  • WordPress plugins let you add almost endless functionality to your site easily and very inexpensively.
  • WordPress plugins give you almost endless expanding capabilities.
  • Plugins allow business owners to own a web presence that they can fully manage.
  • Most plugins will work “right out of the box” and only require installation and activation to give your site new capabilities and functionality.
  • Some plugins can be slightly more complex and require some initial configuring.

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

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

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

WordPress Plugins – Some Useful Tips

  • There are lots of great WordPress plugins available. Be careful not to overload your site with an excessive amount of plugins, as this can start to affect your website’s performance and page loading speed. It can also create more maintenance work for you as a result of potential conflicts.
  • Only keep those plugins that you really plan to use. Delete any plugins from your site, as these utilize server resources.
  • Many free plugins typically come with very little to no support from the plugin author. When choosing premium WP plugins, ensure that you check some reviews online and see what kind of reputation the developer has when it comes to providing support, updates, new features, etc. Be sure to check our plugin recommendations for additional information.
  • If you see that a plugin has not been updated for a very long time (e.g. two or more years), then think carefully before using it on your website or blog. WordPress changes on a regular basis and older plugins that have not been updated can create problems.
  • Ensure to always upgrade your plugins. Older plugin not only can create errors and conflicts, they may also contain vulnerabilities that could be exploited by hackers and malicious software.

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