Google Analytics Tool

[alexja]

Based on my company current needs, I am seriously considering shifting to any advanced analytics tool (Currently using Google Analytics). I hope the community can help me choosing one.

Here is what we need to track. I will try to explain in steps for easy understanding

1. We have a lead capture form (contactus.html) and google tracking code placed on the conversion page (thankyou.html)

2. The form submitted data will get stored in our sales force software (stored as email messages).

3. Lets assume we get 10 leads (emails) in a day. Getting deeper, out of 10 emails we received, The "first 5 emails" were referrals from 'Site A' (i.e. Visitors who clicked our website URL placed on Site A, filled the form and reached conversion page). The "second 5 emails" were referred by search engines. This information can be tracked from Google Analytics (i.e., which referral has sent how many leads).
