WP Plugins Expand Your Blog's CapabilityOne of the most powerful benefits of the WordPress website management platform is that you can easily enhance your WP website or blog’s functionality using plugins.

What Are WP Plugins?

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

You download and install an app!

An app is a software application that is very simple and easy to install and integrates new functionality into any mobile phone.

(Just as you will find social sharing apps …)

A plugin is quite similar to an app. You install a little piece of software that adds new functionality to your WP web site …

Typically, adding a new feature to an existing website involves additional cost. Depending on the complexity of the new feature or enhancements, the cost can be significant, particularly if it requires editing code.

This is also applicable when creating a new website or business blog. Many organizations will often invest money in advance in features they may probably never need.

For sound, strategic business planning reasons, we suggest a cost-effective approach when developing your website and WordPress plugins are ideal for helping you achieve this.

Imagine being able to:

1) Start simply with minimal cost involved. Get a professional business website up and running fast, then …

2) As more features or functionality are needed, simply add new applications with a couple of mouse clicks that integrate seamlessly with your web site, giving your web site a completely new and expanded range of practical functionality, and …

3) Cost not a single cent extra to add to your web site?

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

Benefits Of Using WP Plugins

Earlier, we compared plugins with apps. In a similar way that many apps are free to download and some apps may cost a little money, so do plugins.

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

Plugins that you purchase are called ’Premium’ plugins. The good news, is that when you compare these to the price of investing in web development services to get similar features and functionality on your site, most Premium (i.e. paid) plugins are priced quite cheaply.

Also, since WordPress is an Open Source application, any person can create, modify and customize any part of the WordPress code. This has allowed many professional web developers to create more plugins that expand the WordPress application than you can probably imagine.

  • WordPress plugins let you get started with a basic site and expand only when required.
  • WP plugins allow you to add practically unlimited functionality to any online business presence quickly and really cheaply.
  • WP plugins give your website practically unlimited expanding capabilities.
  • Plugins allow ”non-techies” to have a web presence that they can fully manage.
  • Most plugins will typically work “right out of the box” and only require installation and activation to give your web site new capabilities and functionality.
  • Some plugins are a little more advanced and require some configuration.

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

Additional Tips About Plugins

  • There are many plugins to choose from. Be careful of overloading your site with an excessive amount of plugins, as this can affect your website’s resources and site loading speed. It can also mean more maintenance issues for you as a consequence of possible conflicts.
  • Only keep those plugins you really need. Delete any plugins you don’t use from your site, as these use extra resources.
  • Many free plugins normally receive little to no support from the plugin developer. When choosing premium WP plugins, make sure you check some reviews online and see what kind of reputation the developer has when it comes to providing support, upgrades, new improvements, etc. Be sure to check our plugin recommendations for more useful information.
  • If you see that an unsupported plugin has not been updated for a while (e.g. two years), then think carefully before installing it on your site. WordPress is updated on a regular basis and older plugins can create conflicts.
  • Make sure that you always upgrade your plugins to their most recent software version. Outdated plugin not only can cause issues, they may also have vulnerabilities that can be exploited by hackers and malicious software.

A Basic Guide To WP Plugins

As you can see, plugins are an integral part of WordPress and contribute to making it the most downloaded web management software in the world. Plugins also provide WordPress users with easy, simple and inexpensive ways to add instant functionality to their website without spending thousands of dollars on outsourced web development.

One last thing on the topic of plugins:

If there is any feature or functionality you need for your website, you can guarantee that a WP plugin probably exists that will do what you want it to do, and that it will either be available for FREE, or if it’s a paid plugin, that it will be fairly inexpensive.

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 plugin is not available, then a custom plugin that does exactly what you need it to do can certainly be created for your business at a reasonable cost.
