Track one-time GA event for new user registrations

Question

On the face of it this seemed like it would be something simple to implement, and a common requirement given how important a metric it is, however after a lot of searching and work around ideas this seems to not be the case (I would like to avoid writing a custom plugin for something so basic).

Can anyone offer suggestions on how to do this simply (no hopping through meta redirects) and keep it strict? Or maybe there is a plugin I have missed? The registration system in question is using zoo_visitor and does not require email authentication.

Thank you.

Based on the comments from madebyhippo's suggestion, use the free Session add-on (http://devot-ee.com/add-ons/session-variables-plugin).

So in your generic site header template (throughout the site), have a conditional similar to:

{if logged_out}{exp:session_variables:set name="registration" value="no"}{/if}

Then on the page that get's shown on successful registration check this on a conditional and will prevent refresh issues.

{if logged_in}
  {if "{exp:session_variables:get name="registration"}" == "no"}
    {exp:session_variables:set name="registration" value="yes"}
    {!-- ADD YOUR GA CODE HERE --}
  {/if}
{/if}

Depending on your server session reset it may be possible to re-trigger if they try that "successful registration" page at a later date, but that's going to be on extreme cases.

You could even go to the further extreme of auto-submitting a user account edit form on the success page to save a custom user field and use that instead of the session variable.

An Obvious thought would be to put a Google click track on the registration button? Since users can only register once, this would do the job wouldn't it?

Why do you need to track registrations via Google? Surely a count of the active members would do the same thing?
