Using WordPress Plugins To Enhance Your Site's FeaturesOne of the most useful benefits of choosing the WordPress website publishing platform is that you can easily expand your WordPress site’s functionality using plugins.

Understanding Plugins

Like most people, you probably own a cell phone. What do you do when you would like access to something new on your device like a new game or tool?

Why, simple … you download and install an app!

An app is a little software that is very easy to install and integrates new features into your mobile phone.

(Just like you will find social sharing apps …)

A plugin is really similar to an app. You install a software that adds new functionality to your WP site …

(… there are also social sharing plugins for WP sites!)

Normally, expanding the functionality of a site involves additional cost. Depending on how complex the new features or enhancements are, this cost can be quite significant, particularly if it involves editing code.

This also applies when creating a new website or business blog. Companies often invest money in advance for features they probably will never need.

For sound, strategic business planning reasons, we recommend a modular strategy when growing your web site and WordPress plugins are ideal for doing this.

Imagine if you could:

1) Start simply and inexpensively. Get your web site up and running quickly, then …

2) As new features and functionality are required, just install new software modules with just a couple of mouse clicks directly from your administration section, giving your website or blog a whole new range of features and functionality, and also …

3) Cost not one cent extra to add to your site?

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

WP Plugins – Benefits & Advantages

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

In fact, many wonderful plugins can be downloaded to your website for free.

WordPress plugins that you buy are referred to as ’Premium’ plugins. The good news, is that when you compare these to the cost of hiring a professional web developer to get similar functionality on your site, most Premium plugins are priced quite low.

Also, as WordPress is an Open Source application, any web developer can create, edit and customize any part of the code. This has enabled many third-party web developers to enhance the core WordPress software application.

  • Plugins let you start off with a simple yet professional web site and then add new features and enhancements to your site if necessary.
  • WordPress plugins allow you to add practically unlimited features to your web presence quickly and inexpensively.
  • WP plugins give you virtually endless expansion capabilities.
  • Plugins allow ”non-techies” to own a site that they can self-manage.
  • Most plugins will typically work “right out of the box” and only require installation and activation to give your website instant new capabilities, enhancements and functionality.
  • Some plugins can be slightly more advanced and could require some initial configuration.

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

WP Plugins – Useful Tips

  • There are lots of WordPress plugins to choose from. Be careful not to overload your site with too many plugins, as this can begin to affect your website’s performance and page loading times. It also means more maintenance work for you resulting from potential conflicts and errors.
  • Install only the plugins you really use. Delete inactive plugins from your site, as these also utilize resources.
  • Many free plugins normally receive little to no support from the plugin author. When considering paid WP plugins, ensure that you check around a little and understand what kind of reputation the developer has when it comes to offering support, upgrades, new features, etc. Be sure to check some of our WordPress plugin recommendations for more useful 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 using it. WordPress updates on a regular basis and older plugins that have not been updated can cause errors.
  • Ensure to always upgrade your plugins to the most recent software version. Outdated plugin not only can create problems, they could also contain vulnerabilities that could be exploited by hackers and malicious software.

A Guide To Understanding WordPress Plugins

As you can see, WordPress plugins are an integral part of WordPress and contribute to making it the most preferred content management system in the world. Plugins also provide WordPress users with easy, simple and inexpensive ways to expand without having to spend thousands of dollars on outsourced web development.

One last thing on the subject of WordPress plugins:

Whatever feature or functionality you need for your web presence, you can be sure that a WordPress plugin currently exists that will do just what you need, and that it will either be available at no cost, or if it’s a paid plugin, that the price to purchase it will be reasonable.

And, if by any chance this WordPress plugin is not available, then a custom plugin that does just what you want it to do can probably be created for your business for a very reasonable price.

Hopefully, this information has given you a better understanding of plugins – what plugins are and how they can help improve your WordPress web site. See our published posts to learn more about using WP plugins.
