Web　pages　are　an　important　human-computer　interface,　and　the　layout　of　Web　pages　has　an　effect　on　visual　search.　This　study　focuses　on　using　eye-tracking　to　explore　the　relation　between　information　forms　and　locations,　as　well　as　the　impact　of　floating　advertisements　(ads　for　short)　for　visual　search　on　Web　pages.　The　results　show　that　for　the　information　presented　as　text,　the　fixation　duration　in　quadrant　I　(right　upper),　II　(left　upper)　and　III　(left　lower)　are　shorter　than　in　quadrant　IV(right　lower)　and　the　center　area;　for　the　picture,　the　fixation　duration　in　quadrant　II　is　the　shortest　and　in　quadrant　III　is　the　longest.　No　matter　what　location　the　information　is　placed　on　a　Web　page,　there　is　no　significant　difference　between　the　Web　page　with　floating　ads　and　without　floating　ads　on　the　fixation　duration,　which　indicates　that　floating　ads　have　no　significant　effect　on　the　layout　of　Web　pages.　The　results　suggest　that　the　important　information　whether　text　or　a　picture　is　suitable　to　place　in　quadrant　II;　however,　it　is　the　worst　for　the　layout　of　Web　pages　to　arrange　text　information　in　quadrant　IV　and　the　center　area　or　picture　information　in　quadrant　III.　©　2009　Springer-Verlag.
