Im definately no authority on the
AM side (yet) however whats your search traffic like? Are you getting many visitors? How are you measuring your visitors? Are you running a blog, if so are visitors only visiting your main page or are they delving deeper and looking at your specific posts? Once you understand a little more about what your visitors are doing you can tweak your site further and hopefully increase converstions.
If you need some help setting up something like Google Anayltics, let me know and i can give you a hand if you like.
