WordPress’s popularity is in many parts thanks to its amazing ease of use, second to none functionality, and a huge variety of tools that allow us to take a website to the next level in little time.

Aside from creating pages and posting content, WordPress lets us customize our business’s look and functionality, and we don’t even have to be a developer with coding experience to make it happen.

We have WordPress’s plugins to thank for that, which is why we will be taking a look at them in this post.

We will look at what WordPress plugins are, what they do, and the best ones you should use for your website.

If that sounds like something you’re interested in, make sure you stick around.

What Are WordPress Plugins?

WordPress plugins are pieces of software plugged into a WordPress website. They are similar to apps on your phone.

They are downloaded and purchased to enhance or give your website new functionality. 

Plugins are super useful because they allow users to produce powerful and efficient WordPress websites without having to touch a single bit of code.

Helping you create almost any type of website, from online portfolios to your very own eCommerce site, plugins make small and large changes to your site depending on its specific use and functionality.

For example, we can use a Facebook share plugin to place a Facebook sharing icon on every page of your website to connect your audience directly to your other social pages.

You could also use this plugin to let customers make bookings or contact you. 

You will also come across plugins that help you develop better contact forms, insert image sliders into your website, and also back up your website in the event of malfunctions. 

While a lot of plugins tweak the front of a website, others are capable of making changes to the backend too. This makes website maintenance a lot easier.

You could scan the site, check for bugs, and work on your site in maintenance mode. 

How Does A WordPress Plugin Work?

WordPress plugins improve website functionality without changing any core files. They use clever access points otherwise known as filters or action hooks to hook themselves into a website’s source code.

The action hooks are provided by WordPress’s Plugin API.

The access points call on each plugin’s functions at a specific time before modifying the default behavior of the WordPress (Also check out WordPress Vs Webflow) site.

Developers can create their own plugins by first making a PHP function. An example of a PHP function could be someone telling a plugin to delete spam comments from their site.

The plugin will then use its hook to target an event and remove it. The PHP function could be designed to save comments to a database or to publish a post.

This can be done by making use of the add_action() function or add_filter() function.

Now you know what a WordPress plugin is and how they work, let’s look at how you add them to your website.

There are a number of ways in which you can add a WordPress plugin to a website. The most popular of these ways is to do it from the WordPress dashboard using WordPress’s official directory.

The beauty of using plugins directly from WordPress’s directory is that they can be installed automatically in just one click.

Installing a plugin from WordPress’s directory is super easy. Simply log in to your WordPress dashboard and click on Plugins > Add New.

All you need to do then is click Activate and follow any instructions the plugin might need you to follow. 

To download a plugin that isn’t in the WordPress directory, you first need to download the chosen plugin as a zip file. From here you should save it in a folder called wp-content/plugins.

You will have to do this via FTP. This will then automatically install your chosen plugin on your website. 

When that’s done, head to the Plugins admin section on the dashboard. From here, search for the plugin and click on the Activate link. This will set the plugin up for you.
