What is a WordPress plugin?

A plugin is a PHP script that, after activation, extends the WordPress installation with a specific functionality. There is a plugin for almost every function – from simple linking to social media profiles to complex shop systems. The extensions are often available free of charge.

How do I install a WordPress plugin – automatically vs. manually?

There are three ways to install a plugin in WordPress, which we will explain below using the Monster Insights plugin as an example.

Automatic installation of WordPress plugins

To do this, log into your WordPress backend. Click Plugins in the left menu bar. Under Installed Plugins you will see all previously installed plugins, regardless of whether they are activated or deactivated. To add a new plugin, click Install. In the “Browse Plugins” search bar, enter a keyword or the name of the plugin. In our example, you can search directly for Monster Insights or Google Analytics. In both cases you would see our example plugin. Now click on Install now – the process will now start automatically. The plugin can then be activated – it then appears in the left menu bar.

Manual WordPress plugin installation – upload zip file

Some plugins are not offered directly in the WordPress installer. On WordPress.org you will find a huge plugin library. You can also search by name or keywords here. Click on the desired plugin and select Download. Save the zip file in a place you can easily find. Switch to your WordPress backend and open the Install Plugins menu item. Now click on the Upload Plugin button. Select the file and click Install Now. After uploading, a new page will open where you can now activate the plugin.

Manual installation of WordPress plugins – via FTP

For example, if you have developed your own plugin or get your plugins from other sources, you have to upload them to your server manually via FTP. To do this, connect to your web space using an FTP client (e.g. Filezilla) and upload the fully unzipped plugin folder to the wp-content/plugins folder. Then switch to your WordPress backend and update the view of the installed plugins. If the upload was successful, the plugin will be visible there and can be activated.

After activation, you usually have several setting options available. You should also directly check the functionality on your website.
