Tracking outbound link clicks counts toward your monthly billable page views.
Tracking outbound link clicks requires adding the pirsch-extended.js script to your website. If you have installed the regular pirsch.js and/or pirsch-events.js scripts that track page views and events, you need to replace them with the extended script. The extended script combines the functionality of the other scripts, including the tracking of file downloads and 404 error pages.
Navigate to the settings page in the dashboard and select the Integration tab. Copy the code snippet for your domain and add it to the `head' section of each page you want to track outbound links on. Here is a simple example of what it will look like. You can use the advanced options on the settings page to customize the snippet.
