A plugin adds functionality to WordPress, such as forms, search tools or integrations. Install only the plugins needed for your website and test the result, because several plugins performing the same job can create conflicts and unnecessary maintenance.

01 Choose and prepare
Search for the exact plugin name and check its author, update history, supported WordPress versions and documentation. Read the requirements for paid services or companion components. A directory listing does not mean every feature is free or that the plugin is suitable for your particular theme and other extensions.
Make a current backup before adding code to a production website. Test plugins that affect checkout, accounts, caching or security on staging first.
02 Install the selected plugin
- Open Plugins > Add New Plugin as an administrator. On Multisite, the network administrator controls installation.
- Search the directory and open the plugin details to confirm that you selected the intended product.
- Select Install Now and wait for completion. Installation alone does not necessarily enable the plugin.
- Select Activate when ready, then follow the plugin's documented setup process. Configure only the permissions and integrations the intended task requires.
How do I confirm that the installed plugin works?
Test the feature from a visitor's perspective. For a contact form, submit a controlled message and confirm delivery; for a redirect tool, test the exact source and destination. Check both signed-in and signed-out behaviour when they differ.
If activation causes an error, record the message and deactivate the plugin through the available recovery route. Avoid activating several new plugins together, which makes the cause harder to isolate. Do not enter unrelated account passwords into an unfamiliar setup prompt.
03 Keep it maintained
Record who owns the configuration and any licence or service subscription. Review updates and remove the plugin if it is no longer needed after preserving its data. A missing Add New button can reflect permissions, Multisite or a managed restriction; it is not a reason to share your administrator login with another user.
