I think you need to break your use cases up:
1. Am I in ecommerce will this work with a shopping cart?
2. CMS or blogging platform? ad based?
3. Conversion funnel Saas or lead gen?
what if I have sever generated content will it work with my site?
Also, is this targeted at conversion experts? or novices?
Next, if I have all this content how do I get it into your system?
And, I think you need to spell out better the value prop.
Would you like to drop "the cost to get customers" like a rock?
