This is a great question.

I would take this time to run through a thought experiement I like to ask companies I work with in similar situations.

Problem vs. Symtom

Your goal is to improve conversions and capture more leads from the traffic you currently have.

You are assuming the problem for your high bounce rates are actually because you don't have the proper "tools"

When in reality your high bounce rate is the symtom of something else.

Tools are great but they won't help your problem you face at its core.

*is the traffic source your driving traffic from the right one?
*Is your website horribly designed?
*Is the content and copy on your website not adding any value or grabbing the attention of your visitor?
*Is your service or product not positioned correctly?

I would start there before trying to find the "tool" because more than likely your real problem can be fixed or addressed sooner then you think.
