2009年全球廣告總量將會降低 6.9%，而網路則會是唯一廣告量成長的媒體。網路廣告中又以關鍵字廣告（Ad Copy）與橫幅廣告（Banner Ad）所佔總體網路廣告營收的比例最高。關鍵字廣告為當網路使用者搜尋資訊時，鍵入關鍵字，文字廣告即會出現在搜尋結果的網頁中，與網路使用者的搜尋意圖互相連結；而橫幅廣告（Banner Ad）為靜態或動態之圖像式廣告，網路使用者點擊後可連至廣告主網頁。 本研究探討屬性組合如何影響關鍵字廣告（Ad Copy）與橫幅廣告（Banner Ad）之廣告效果，與B2B企業研華股份有限公司（Advantech Corporation）之數位行銷中心（Digital Marketing Center）合作，配合Google AdWords平台進行廣告投放之實證研究，觀察廣告之點擊率。為了解屬性組合如何影響廣告效果，本研究分為兩個部分：關鍵字廣告（Ad Copy）與橫幅廣告（Banner Ad）。關鍵字廣告（Ad Copy）部分，以「文化差異」與心理學理論之「自由需求（自由感）」之有無為自變項；橫幅廣告（Banner Ad）部分以「廣告尺寸」、「訴求導向」與「廣告主題」為自變項，兩種類型廣告之研究皆以廣告「點擊率」為應變項，試圖觀察不同屬性組合之下的廣告效果，以供B2B企業在執行網路行銷時之參考。 研究結果發現，在具「文化差異」之國家下投放「自由需求（自由感）」之有無的關鍵字廣告（Ad Copy），其廣告點擊率具顯著差異；而「廣告尺寸」、「訴求導向」與「廣告主題」此三屬性組合下，「方型（300 x 250） x 應用領域資訊 x USP」此一廣告屬性組合獲得最佳之廣告點擊率。透過研究觀察，B2B企業可以此為未來關鍵字廣告（Ad Copy）文案撰寫與橫幅廣告（Banner Ad）文案設計之方向。 / Internet has become the second large media in recent years.
