I have some pages that are just loaded with content--everything you ever wanted to know on the subject. They don't do well with Adsense.

(I have 3 sets of Google ads going down the left margin, making these pages about 4 screens long, and the content matches that length.)
I have other pages, where I don't have that much expertise, so the page has just a few paragraphs of original content and a few links. (These pages would only have one set of Google ads down the left, making them slightly more than 1 screen long.) Those do much better with Adsense.
I'm starting to think that people are coming to my weaker pages, not finding what they need, and therefore clicking my ads to find what they're after somewhere else.
When they come to my good pages, they get everything they want so there's no need to click on my ads.
It looks like I'm getting rewarded for my weak content and punished for my strong content.
Please let me know what you all think about this. Maybe the answer is to chop up my long articles into a bunch of smaller pages and make people click more to get it all. HEEELLLLPPPPP!!!!

PS--after thinking about this some more, maybe it's just that general informatin pages do better than detailed "how-to" pages. Have you folks found that to be true?
