The 2Performant Link2 WordPress plugin is a light tool (~2KB) that makes life easier for 2Performant affiliates who use WordPress as their CMS. It runs in the browser (doesn’t make load on your server).
The plugin embeds a 3rd party script from 2Performant (https://cdn.2performant.com/l2/link2.js) in the footer of your WordPress site. The script automatically transforms direct links to advertiser pages/products into affiliate links.
Without the plugin, the script should be added manually to the theme.
