Generally, if you plan to add new features to your web site, additional cost is involved. Depending on the complexity of the features or enhancement, things can get fairly expensive, especially if website developers need to add new code or edit code or develop scripts to integrate with your current set up.

This is also applicable when creating a new web site. Organizations will often invest money in advance in components they may never need.

For this reason, we suggest a sustainable strategy to developing your website and WP plugins are ideal for doing this.

Imagine being able to:

1) Start simply and with minimal expense involved. Get a basic, professional-looking website up and running quickly, then …

2) As the need for new capabilities arises, just add new applications with a couple of mouse clicks directly from your WordPress administration section, and give your website or blog a completely new range of useful functionality, and …

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

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

Plugins – Benefits

Earlier, we compared plugins with smartphone apps. In a similar way that many apps are free to download and some apps cost a little bit of money, the same is true with WP plugins.

In fact, thousands of fantastic plugins can be downloaded and installed on your websites.

WordPress plugins that you have to pay for are called ’Premium’ plugins. The good news, is that when you compare these to the price of investing in professional web development services to add the same functionality on your site, most Premium (i.e. ”paid”) plugins cost very little.

Also, because WordPress is an Open Source application, anybody can create, rewrite and customize any part of the code. This has enabled thousands of third-party web developers to build more applications that plug seamlessly into WordPress than you can imagine.

Useful Things You Should Know About Plugins

  • There are loads of great WordPress plugins available. Be careful of overloading your server with an excessive amount of plugins, as this will affect your website’s resources and site loading speed. It can also mean more maintenance issues for you resulting from potential errors.
  • Only keep those plugins that you really need. Delete inactive plugins from your site, as these also consume resources.
  • Many free plugins normally receive very little to no support from the plugin author. When choosing premium plugins, ensure that you check some reviews online and see what kind of reputation the developer has when it comes to offering support, updates, new improvements, etc. Be sure to check some of our WP plugin reviews for more helpful information.
  • If you see that an unsupported plugin has not been updated for a very long time (e.g. two years), then think carefully before using it on your site. WordPress updates regularly and older plugins that have not been updated can cause problems.
  • Make sure that you always keep all plugins upgraded to the latest software version. Older plugin not only can create issues, they could also have security vulnerabilities that can be exploited by hackers and malicious users.
