This　study　investigates　the　characteristics　of　visual　search　and　browsing,　and　analyzes　the　differences　of　those　strategies　on　Web　pages　using　the　eye　tracking.　When　participants　search　on　Web　pages,　the　peripheral　area　is　significantly　higher　than　the　central　area　on　fixation　duration　and　fixation　count;　when　participants　brows　information　on　Web　pages,　there　is　no　significant　difference　between　the　peripheral　area　and　the　central　area　on　fixation　duration　and　fixation　count.　Visual　search　is　significantly　larger　than　browsing　on　the　average　pupil　diameter,　which　shows　that　the　mental　load　on　visual　search　is　significantly　greater　than　that　on　browsing.　Results　show　that　the　visual　search　strategy　pays　more　attention　to　the　peripheral　area　than　the　central　area;　however,　the　visual　browsing　strategy　freely　run　their　eyes　over　the　peripheral　area　and　the　central　area　in　equality.　The　differences　between　the　visual　search　and　the　browsing　strategies　are　mainly　due　to　the　goal-driven　and　the　mental　load.
