All I get on that page are public service ads. And it's not because the page is new, newer pages on my site have targetted ads, this is the only page with the public service ads.
I've seen the high paying ads show up on another page that has a much lower keyword density and isn't in any way optimized for those words.
Did I overdo it and trip a filter?
Then, check to see if there is a stop word filter you might have tripped (ie. the filter that prevents ads from showing up on pages about deaths or terrorist attacks, etc).
What was the difference in keyword density between the two pages? It is very probable there is a filter, as a prevention against showing ads on keyword spam pages.
I created a page on my website that was rich in words that I thought would be likely to elicit Adsense ads that pay a lot of money per click.
Remember that pages have to have real content and that Google do manual checks of the sites their ads run on. From your description, I wonder if your page may not have passed the "smell test".
For example, say you have articles on your sites about widgets and you happen to talk about purple widgets in a bit more detail. You decide to put AdSense on the page, and discover purple widget ads. But you know green widget ads are worth 4x the amount of purple widgets. I don't think there is a single publisher here who wouldn't change their example from purple widgets to green ones ;)
The same can be applied to just about any content. Slight tweaking of pages can make a difference in the ads shown, but there very likely is a line that can be crossed - you just have to know where that line is to be successful doing it.
It is really no different than making sure to use ranking keywords in content when optimizing a page for the search engines. But there is a difference between keyword spam pages and quality content with those juicy keywords utilized legitimately. It doesn't mean Small Website Guy is doing anything wrong or bad at all - unless it is a page just filled with keywords - but I read it to mean actual content optimized with higher paying keywords to get higher paying ads to show, but that the keyword density might be dialed up a bit too high for the mediabot's liking.
