Installing a WordPress plugin lets you extend the functionality of the admin panel and your website, or add extra features to how it runs. WordPress plugins are like small building blocks of functionality. You can install as many plugins as you like, depending on what features you want your site to have.
Some of the most popular features that WordPress plugins add to your website and admin panel include:
- a WordPress contact form,
- an advanced image gallery,
- Google Analytics and SEO ranking tools,
- online payment and sales tools,
- banner systems, ad systems, and more.
Installing WordPress plugins takes just a few seconds, and you can do it right from your website's admin panel.
Installing a Plugin from the WordPress Library
The WordPress plugin library is available directly in your website's admin panel and gives you access to thousands of ready-made features. Pick a plugin, install it, activate it, and start using it. Installing a plugin from the library is free, but some plugins offer paid Premium options.
- Log in to the WordPress admin panel.
- Go to the Plugins > Add New section
- Find a plugin you're interested in from the gallery, using the search box or popular filters like Featured, Popular, Recommended, and Favorites.
- Click Install.
- Click Activate. You don't have to activate the plugin right away — you can do it anytime from the Plugins > Installed Plugins.
- If you've activated the plugin, it's ready to use.
How to Install a Plugin from a File?
Installing from a file lets you add a WordPress plugin that isn't available in the official CMS library — for example, one built for you by an outside agency. Installing from a file means selecting the file to upload to the server. After that, you can activate and configure the plugin just like any other.
- Log in to the WordPress admin panel.
- Go to the Plugins > Add New section
- Upload the plugin to the server.
- Select the plugin file and click Install.
- Click Activate. You don't have to activate the plugin right away — you can do it anytime from the Plugins > Installed Plugins.
- If you've activated the plugin, it's ready to use.
WordPress Plugins and Hosting Performance
Every plugin adds more code running on your site, so it's worth installing only the add-ons you actually need and that are updated regularly. Too many plugins can slow down the admin panel, increase CPU/RAM usage, and make it harder to keep the site secure.
WordPress Toolkit in Plesk helps you keep track of updates, security, and the overall health of your installation. For WooCommerce stores, it's especially important to test changes before updating the live site.
