There are Google Analytics plugins that have been created to allow for tracking, statistics, etc. for WordPress sites.
These plugins can provide quick access to in depth reports and a dashboard for easy views of statistics. Potential options can be found when searching for a terms like:
- User Tracking

We have not developed these plugins but a variety of these types of options can be found in the WordPress Plugins Directory.
Or, you can consider placing your Google Analytics code on a WishList Member Registration page.
You can customize the registration page for a Level by adding HTML above and/or below the form.
This can be accessed in the Setup > Levels > *Click on Level Name* > Registrations section of WishList Member.
The option to enter HTML above and/or below is available for each Level.
