At SMX Advanced tonight, Google's head of search spam, Matt Cutts explained that if Google's search results pages were run through the top heavy algorithm it would not be hurt by that algorithm. So if you wanted another guide to whether you're safe from Top Heavy, perhaps the ratios of ads to content with Google's pages would be a guide.
Matt Cutts clarified what he meant for me, explaining that in general most of Google's search results pages do not have ads at all. So when you look at the Google search results as a site, not specific pages, overall, the ad to organic ratio is very low.
