Adding New Features And Functionality To Your Web Site With WordPress PluginsOne of the most unique advantages of using the WordPress platform is that you can quickly expand your WP website’s functionality using applications called ’plugins’.

About WordPress Plugins

No doubt, you probably have a smart phone. What do you do when you want to access something new on your phone like a new application, game or business productivity tool?

An app is a software that is very simple and easy to install and immediately adds new features to any smart phone.

Typically, if you want to add a new feature to an already-built website, additional cost is involved. Depending on how complex the new feature or enhancement is, this cost can be fairly significant, particularly if web developers need to create new code or edit programs or install programs to integrate into your existing site.

This is also applicable to creating a website or business blog. Businesses will often spend up-front on features and options they may never need.

For this reason, we recommend considering a cost-effective approach when developing your website and WP plugins are ideal for helping you achieve this.

Imagine being able to:

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

2) As you need more features or functionality, simply install new applications with a few clicks of the mouse directly from within your WP administration panel, and give your website a completely new range of possibilities, and also …

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

Well, that’s precisely what a plugin lets you do!

Benefits & Advantages Of Using Plugins

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

In fact, thousands of fantastic plugins are freely available for WordPress users.

Plugins that cost money are referred to as “Premium” plugins. The good news, is that when you compare it to the price of hiring a professional web developer to get the same features and functionality on your site, most Premium plugins are priced quite low.

Also, since WordPress makes its code publicly available, any person can create, edit and customize any part of the code. This has enabled thousands of professional web development companies to create more new tools that integrate with the WordPress software than you can imagine.

Useful Things To Know About Plugins

  • There are loads of fantastic plugins to choose from. Be careful of overloading your site with an excessive amount of plugins, as this will affect your website’s performance and page loading speed. It can also create more maintenance issues for you resulting from possible conflicts and errors.
  • Only keep the plugins that you really need. Delete inactive plugins from your site, as these use extra server resources.
  • Many free plugins often come with little to no support from the plugin author. When choosing paid plugins, ensure that you do a little research first to see what kind of reputation the plugin 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 an unsupported plugin has not been updated for a very long time (e.g. two or more years), then think twice before installing it on your website or blog. The WordPress core application updates regularly and older plugins that have not been updated can cause conflicts.
  • Always keep all plugins up-to-date. Outdated plugin not only can create errors, they could also have security vulnerabilities that can be exploited by hackers and malicious software.
