adding adwords tracking to a Click instead of a page load using goog_report_conversion I am using the simple subscription module to subscribe users to a newsletter and wish to track clicks of subscribers.  Is there an easy way to call the goog_report_conversion() function when someone clicks on the subscribe button? I don't see any configuration for this with the simple subscription module.
General advice: don't use "simple" modules for non-simple tasks.

No easy way here, you need to inject your JavaScript code, and attach additional behavior to that button. Worse, you would need to make sure there is enough time for function to process. My colleagues use thank you page if feasible for that very reason - browser will do it's best to minimize time between button click and page load. On thank you page that is not an issue.
