I am working on an ecommerce website with dynamic content. I have a product list page which is also a major landing page. I noticed when I decided to divide my product list page into 2 pages my bounce rate lowered 6% - 7% but now webmaster tools is complaining that there is duplicate content, meta keywords, title, and description on the productlist page 2. It's just basically pulling the same data from the server for productlist page 1 and 2 and the developers say it's going to be very hard to make page 2 grab different data.

What should I sacrifice, the higher bounce rate or the duplicate content?
