jInbound allows you to easily track when a campaign "converts" a site visitor. 

We've made it super-easy to identify converted users: just add a native URL (starting with index.php) in your campaign settings. 

This page should be unique for converted users. 

For an e-commerce site, you might use the native URL that loads the order confirmation page for example. However this could be any page that defines the ultimate goal of the campaign.

When a lead visits the Conversion Parameters URL, their status will be updated to a converted lead (i.e. customer in the example above) and your conversion statistics will be updated.
