I've had a similar situation. My table tennis related site received a fair number of visitors based on keywords that included "Biba" (an attractive female player.) Concurrently, Biba had a number of articles in newspapers and national periodicals. I caved in to my constituents requests and created a Biba gallery. Lo and behold, I would received a surge in traffic once the gallery page was indexed and discovered. Other sites, in particular forums (computer and automobile-related) would post a link to the page which would cause traffic spikes. Even
www.si.com (Sports Illustrated) had a link to the page. As with all of my pages, I have AdSense embedded but additionally I have CasaleMedia banner on that particular page. The monetization increased approximately 200-300% during those surges (from a typical $1 to as much as $3 per day - whoopee!)
My site is hardly an ecommerce site, but I gave the people what they wanted, and received traffic spikes and a few more pennies to boot.
