Installing Easy Affiliate Links
Installing the free Easy Affiliate Links plugin
As the free plugin is hosted on the WordPress.org repository it can easily be installed right from your backend. Just go to the Plugins > Add New page, search for "Easy Affiliate Links", click on the "Install Now" button first and the "Activate" button next.
Alternatively, download the plugin from the repository and install it just like the Premium plugin.
