Sources for buying Adsense-compatible traffic

Is there any source of traffic that AdSense doesn't like?

I have a couple of sites that have exceptional AdSense conversions and would like some advice on buying additional traffic. I want to be careful not to use any source that AdSense wouldn't like (such as cgi-generated traffic which is useless).

How about some suggestions? Thanks.

imho any paid additional traffic would only dilute your "exceptional AdSense conversions"

I think it doesn't exist. If one could offer exceptional Adsense conversions then why would they sell it to others instead of using it themselves and earn a lot more?

Because they don't have time to build content for a million niche sites.

In today's button-pushing world, I don't think "time to build a site" is a problem :)

Let's get back to the original question:

Where do you buy traffic from?
