有別於傳統行銷模式，關鍵客戶行銷變成時下趨勢。企業針對自己的關鍵客戶制定行銷策略，達到節省成本、增加成效之結果。英國網站YouGov利用使用者問券資料進行資料探勘，為每個品牌、人物及議題進行其關鍵客戶的資料分析。在網站上搜尋特定的品牌、人物或議題後，YouGov將關鍵使用者年齡、性別以及喜好做為關鍵客戶的形象，並繪製行銷用人物誌，讓網站使用者能以圖像化的方式，了解複雜的分析結果。但由於問卷調查式的資料蒐集，存在許多人為填寫所產生的問題，如填寫意願、填寫正確性等，因此本研究將關鍵客戶於社群平台的社群互動行為中自我揭露的喜好資訊取出，取代傳統問券調查的資訊蒐集，並進行關鍵使用者的生活型態分析。其中包含關鍵使用者偏好及關鍵使用者人物誌形象，並將關鍵使用者生活型態接近的品牌、人物或媒體進行集群，分析它們在同一段時間內是否都有共同討論的議題。本研究使用全球最多的使用者的Facebook做為本研究的數據來源。因Facebook提供的粉絲專頁功能，讓品牌、人物及媒體能免費使用該功能進行行銷宣傳，成為了品牌、人物及媒體能與客戶互動的便利平台。粉絲專頁的貼文功能除了能讓它們公布資訊給客戶，同時也能讓客戶回饋意見。因此，粉絲專頁的資訊含金量極高。最後本研究為將分析結果有效率的呈現給使用者，因此本研究架構一工具網站，並將生活型態分析結果以人物誌呈現；而議題分析結果則以文字雲呈現，盼能讓使用者一目了然的理解複雜的分析結果。
