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 WordPress PluginsOne of the most unique advantages of building a website using the WordPress platform is the ability to quickly increase your WordPress website’s functionality using applications called ’plugins’.

What Are Plugins?

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

You download and install an app!

An app is a little software application that is simple and easy to install and instantly integrates new functionality into any smart phone.

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

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

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

Generally, if you want to expand the functionality of an already-built website, additional cost is involved. Depending on how complex the new feature or enhancement is, the cost can be significant, particularly if it requires website development.

This also applies when creating a website or business blog. Business owners sometimes invest money in features they probably will never need.

To save money and keep your costs down, we suggest a cost-effective approach to growing your website and WP plugins are ideal for doing this.

Imagine if you could:

1) Start simply with minimal expense involved. Get your business web presence up and running fast, then …

2) As the need becomes evident, simply add new applications with only a few mouse clicks directly from your dashboard panel, to give your web site a whole new range of capabilities and functionality, and also …

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

Well, this is exactly what plugins let you do!

WP Plugins – Benefits & Advantages

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

In fact, thousands of plugins can be downloaded to your website for free.

Plugins that cost money are called “Premium” plugins. The good news, is that when compared to the cost of hiring a professional web developer to get similar features and functionality on your site, most Premium (i.e. paid) plugins cost very little.

Also, because WordPress makes its code publicly available, any web developer can create, edit and customize any portion of the WP code. This has enabled thousands of third-party software development professionals to create more new plugins that plug seamlessly into WordPress than you can probably imagine.

  • Plugins let you start off with just a simple web site and then add new features and enhancements to your site only if necessary.
  • Plugins let you add almost endless functionality to any site easily, quickly and very cheaply.
  • Plugins give you almost unlimited expansion capabilities.
  • WordPress plugins allow non-technical website owners to have a website that they can manage themselves.
  • Most plugins will normally work “right out of the box” and only require to be installed and activated to provide your website or blog with immediate capabilities and enhancements.
  • Some plugins offer more advanced options and may require some initial configuration.

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

Just like WP themes, loads of WP plugins are available to WordPress users … often at $0 cost!

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

Additional Information About WordPress Plugins

  • There are loads of WordPress plugins available. Be careful not to overload your site with an excessive amount of plugins, as this can affect your site’s performance and page loading times. It also creates more maintenance work for you as a consequence of potential conflicts.
  • Install only those plugins that you really plan to use. Delete any plugins you don’t need from your site, as these use additional resources.
  • Many free plugins typically receive little to no support from the plugin developer. When choosing premium WP plugins, make sure you check around a little and understand what kind of reputation the plugin developer has when it comes to providing support, updates, new features, etc. Be sure to check the plugin reviews we publish on this site for additional useful information.
  • If you see that a plugin has not been updated for a while (e.g. two or more years), then think carefully before using it on your website or blog. WordPress updates frequently and older plugins that have not been updated can create issues.
  • Always update your plugins. Outdated plugins not only can create errors and conflicts, they could also have vulnerabilities that could be exploited by hackers and malicious software.

One last thing on the subject of WP plugins:

Whatever 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 need it to do, and that this plugin will either be available at no cost, or if it’s a paid plugin, that the price 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 WP plugin does not exist, then a custom plugin that does precisely what you would like it to do can probably be created for you for a reasonable price.
