WordPress Plugins Expand Your Website's CapabilitiesOne of the main advantages of building a website using the WordPress platform is the ability to quickly and easily expand your WP website’s functionality using inexpensive (and often free) applications called plugins.

What Are Plugins?

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

Why, simple … you download and install an app!

An app is a piece of software that is easy to install and integrates new features into your mobile device.

(Just as there are social sharing apps for mobile phones …)

A plugin is similar to an app. You install and activate an application that provides new functionality to your WP website or blog …

Normally, adding new features to an existing site involves additional cost. Depending on the complexity of the features or enhancement, the cost can be significant, particularly if it requires website development.

This also applies when setting up a new web site. Organizations sometimes invest up front for components they may never need.

For sound, strategic business planning reasons, we suggest a modular approach to developing your web presence presence and WordPress plugins are ideal for doing this.

Imagine being able to:

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

2) As you need new features or functionality, add new software modules with a few clicks of the mouse that integrate with your web site, and give your web site an entirely new range of practical features and capabilities, and …

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

Well, that’s exactly what plugins allow you to do!

Benefits & Advantages Of WordPress Plugins

I started this article by comparing plugins with mobile apps. In the same way that many apps are free to download and some may cost a little money, the same is true for plugins.

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

WP plugins that you have to buy are called Premium plugins. The good news, is that when you compare it to the price of hiring a professional web developer to get similar features and functionality on your site, most Premium plugins are typically quite inexpensive.

Also, since WordPress distributes its software as an Open Source application, any web developer can create, modify and customize any portion of the code. This has enabled many professional software developers to enhance the core WordPress software application.

  • Plugins let you start off with a simple site and then expand only if necessary.
  • Plugins allow you to add practically endless functionality to your web site easily, quickly and cheaply.
  • WordPress plugins give you virtually endless expansion capabilities.
  • WordPress plugins allow non-technical website owners to have a web presence that they can self-manage.
  • Most plugins typically work “right out of the box” and only require to be installed and activated to provide your website with new capabilities and features.
  • Some plugins offer more extensive options and require some configuring.

WP Plugins – Some Useful Information

  • There are loads of good plugins available. Be careful not to overload your server with an excessive amount of plugins, as this will affect your site’s performance and page loading times. It can also create more maintenance issues for you as a result of possible conflicts.
  • Install only the plugins you really use. Delete all inactive plugins from your site, as these use server resources.
  • Many free plugins often come with little to no support from the plugin author. When choosing premium plugins, ensure that you check around a little and 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 our WordPress plugin reviews for more information.
  • If you see that an unsupported plugin has not been updated for a very long time (e.g. two years), then think twice before installing it. WordPress changes regularly and older plugins that have not been updated can cause conflicts.
  • Make sure to always update your plugins to their latest software version. Older plugins not only can create errors and conflicts, they could also contain vulnerabilities that could be exploited by hackers and malware.

One last thing on the subject of plugins:

If there is a functionality you want for your website, you can guarantee that a WP plugin currently exists that will do exactly what you need, and that this plugin can either be downloaded for FREE, or if it’s a premium plugin, that the price will be quite reasonable.

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