Underlined links, breadcrumbs, new snippets — Google keeps rearranging the visual furniture of the SERPs. How much does a few pixels of extra space really move the CTR?
Hacking the QDR parameter in Google's URL lets you filter results by the last X minutes — or seconds. A small trick, possibly a sign of where real-time search is heading.
