Increased Bounce Rate & Dollar Index?

[airnwater]

We use Google Analytics on our ecommerce site and we recently made several changes to an important page.  Due to logistical reasons, we couldn't perform a Google web optimizer test but tracked the page's numbers in analytics from before/after the changes were made.

After a week, we noticed that the bounce rate on the page went up by about 10% but the dollar index also doubled.  We're trying to figure out how this could happen, since it seems kind of odd. Any feedback would be appreciated.

I personally haven't used the dollar index, so am basing this on the definition I found at http://www.analyticsmarket.com/blog/google-analytics-definitions, which states:

A measurement of how influential a page is to conversion. It doesn't indicate how much money a page brought. Rather, it's a score. The higher the number, the more frequently it was viewed prior to a purchase or conversion. It's calculated by taking the goal conversion value or transaction value of a visit and applying it evenly to all the pages prior to that conversion. Seen in aggregate, it just attempts to correlate pages to conversions.

Have you done something on that page to better qualify your prospects, and encourage them to order more? If you qualified them better, you may have driven away some of the people who were not going to buy or were going to purchase a small amount, increasing your bounce rate but also increasing your dollar index.
