If you're heavily AJAXed up then bounce rate is a meaningless metric for you. I don't know why you'd spend time optimizing for it -- instead, measure a meaningful metric (such as average number of interactions, or number of visitors with at least one interaction, or -- my personal favorite -- sales).

I think there must be a way to mimic the bounce rate in AJAX by firing the onclick event to make it meaningful again.
