I'm assuming I'm not the only one reading this that had no idea Piwik existed. I've been so trained to use GA for years. Thanks Sarah.

For anyone else out there who's curious, it's really easy to setup. They recommend creating your own database, but I just installed it on my existing WP database (WP Engine as a host). And I used the WP-Piwik plugin to add the tracking code.

Appears to be running well, but will give it some time to check on data. I would recommend a separate database because it adds 20 tables to the DB.
