clearspring - the widget network.

Clearspring provides great interaction analytics right out of the box, without you needing to do a thing. But what if you have specific, custom events that you'd like to track as well? What if you want to track clickthrough URLs from your widget?

You can do all of this by adding some simple function calls to your widget code. These calls will let you tell Clearspring every time a specific event happens, or even when your user click on links in your widget. These events will then show up in the reporting interfaces, along with all of the standard tracking.

Developers, take a look at the Track package in the In-Widget Services API. All the calls you need are right there.
