Surf Canyon improves Internet search results using its browser plugin. Once installed, when users go to Google or Yahoo! and enter a search, they'll see Surf Canyon's bull's eyes next to the search results. Clicking on a bull's eye or on a result triggers this application, which makes "instantaneous relevancy" calculations in order to present recommended search results, which are dug out from subsequent pages of the result set. This exension works on Internet Explorer, Firefox, and Chrome.
