It seems likely that the algorithm is counting affiliate links as ads when it can. Your site may using affiliate links in a way that allows them to be detected when maybe your competitors are not.

From what I can gather they also don't want webmasters to push ads below the fold with white space. In other words, there must be more content above the fold than ads above the fold.

I believe that my site was targeted because my interactive javascript content looks like a "call to action". It doesn't actually take up that much screen real-estate. It may actually be counted as an ad by the algorithm.

So move the following down in the page if possible: Ads, third party links, forms, whitespace.

And move up: text, images, flash.
