Google Blurring Distinction Between Ads and Organic Search Results

jfruh writes "For years, paid links returned from Google search queries have been set off from 'real' search results by their placement on the page and by a colored background. But some users have begun to see a different format for these ads: a tiny yellow button that reads 'AD' at the end of the link is the only distinguishing feature. Google is notoriously close-mouthed about this sort of thing, but it may begin rolling the new format out to more users soon."
