The information that is supplied on your web is is immaterial to how much money you make on AdSense. Important are

# visitors
CTR
CPC

Basically you determine the number of visitors and can influence the CTR

CPC depends on what advertisers have bid on the keywords that put them on your page (you can influence this), plus smart pricing that is "meant" to reflect the "quality" of the punters that the advertiser gets from your site (where quality is equated to their propensity to make money for the advertiser)

Whether your web site supplies top rate, new information or merely regurgitates stuff out that does not effect your earning capability on AdSense.
