Normally, expanding the functionality of your site involves additional cost. Depending on how complex the feature or enhancement is, the cost can be fairly significant, particularly if it involves editing code.

This is also applicable to creating a new website or business blog. Business owners tend to pay money in advance for bells and whistles they may not ever need.

For this reason, we suggest considering a modular strategy to setting up your web site and WP plugins are ideal for doing this.

Imagine being able to:

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

2) As the need becomes evident, install new software modules with only a few clicks of the mouse that integrate with your current website or blog, to give your website or blog a whole new and expanded range of useful functionality, and …

3) Cost not one dollar more to download and install on your web site?

Well, this is exactly what WordPress plugins let you do!

WordPress Plugins – Benefits And Advantages

Earlier, we compared WP plugins with mobile apps. Just like many apps are free to download and some may cost a little money, the same applies to plugins.

In fact, loads of wonderful plugins can be downloaded to your website at no cost.

Plugins that you buy are referred to as Premium plugins. The good news, is that when you compare these to the price of paying for professional web development services to add similar functionality on your site, most Premium (i.e. paid) plugins are priced quite cheaply.

Also, since WordPress makes its code available to everyone, anyone can create, rewrite and customize any portion of the WP code. This has allowed many third-party web development professionals to create more new applications that “plug into” WordPress than you can imagine.

  • Plugins let you get started with a simple yet professional online business presence and expand if required.
  • Plugins let you add practically unlimited features to your website quickly and really cheaply.
  • WordPress plugins give your site practically unlimited expanding capabilities.
  • Plugins allow non-technical website owners to own a website that they can fully manage.

WordPress Plugins – Some Useful Things You Should Know

  • There are many great WordPress plugins to choose from. Be careful not to overload your server with an excessive amount of plugins, as this can begin to affect your website’s performance and page loading speed. It also creates more maintenance work for you as a consequence of potential conflicts and errors.
  • Install only the plugins that you really use. Delete inactive plugins from your site, as these use resources.
  • Many free plugins normally come with little to no support from the plugin developer. When choosing paid plugins, make sure you do a little research first to 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 reviews for additional expert information.
  • If you see that a plugin has not been updated for a while (e.g. two years), then think twice before installing it on your site. WordPress updates on a regular basis and older WordPress plugins can cause conflicts.
  • Make sure to always maintain your plugins updated. Older plugin not only can create errors, they could also have vulnerabilities that can be exploited by hackers and malware.
