Piwik not tracking search engine referrals

Piwik has been running for a week now. Ecommerce Magneto site with /piwik-ecommerce-extension-for-magento/. I only get direct traffic results, no search engine referral traffic or keyword results. How do I fix this?

There are redirects setup in htaccess, such as non-www to www. Tracking code is automatically setup on all pages via the magento/piwik extension.

Thank you
