This depends <i>hugely</i> on the audience and what's around them on the page, but I'd guess the most noticeable and therefore most clicked ad would be the Microsoft Paint, No Logo, Gold Car.<p>OTOH, I'd guess the 1st or 2nd ones in the list would be near the top for downloads resulting in paid conversion.<p>But I find these produced ones generally poor, so it's hard to predict.

The <i>real</i> lesson from the last article was "test everything." Likewise, the <i>real</i> lesson from this article is "iterate and improve."<p>I'm totally banking on MS Paint being the most significant variable. The professional-looking ads have a bunch of tiny text in a font/style with poor readability. MS Paint "text" is legible from orbit.
