(This is also partly in response to your other recent comments about wanting to find the highest-paying keywords for your site.)
It's likely to be a futile exercise for many reasons, including (1) Smart Pricing, (2) a rule of thumb is that the more lucrative the niche is perceived to be, the more competition there is, and (3) he might just cause his existing position in the SERPs to plummet if he changes the focus of his site.

[edit reason] Removed specifics. [/edit]
Before martinibuster removed specifics on your second position search terms, I got a chance to visit your site and I must commend you for your excellent work on your flash programs and tools. One way you can effectively improve your earnings is to reduce the numbers of ad blocks and just place one large rectangle above the fold in the center on each page. You will achieve a better CTR and better eCPM, thus larger earnings.
It was difficult for me to make that change at first, but it paid off. I see many new AdSense users making that same mistake thinking that more ads are better. Not so in the AdSense world, with smart pricing and other gimmicks they use to keep us from earning too much.
Writing good content isn't optimal, writing good content and following the rules of SEO is better. I'm sure you do it, I'm sure you researched it, you wanted more users to essentially earn you more money.
