近年來,傳統廣告在行銷傳播工具的重要地位已被數位廣告所取代。但過去的學術研究多著重在數位廣告本身的成效與機制,而少從廣告主的角度來探討,包括產品的涉入程度不同與產品行銷預算多寡,是否影響與數位廣告平台的契合度,讓廣告主能按照自身的產品屬性與預算資源,來制定數位廣告策略與選擇數位廣告平台。 本研究假設廣告關聯性、產品需求程度、以及產品涉入程度,是影響受眾點擊數位廣告與否之決策的三項重要因子。延續此邏輯架構,透過檢視數位廣告發展的沿革,了解評估數位廣告成效的指標,進而討論不同數位廣告平台的特色為何,平台又是如何透過演算法來提升廣告點擊率,以達到廣告主、受眾、平台三贏的局面. 最後總結出影響廣告主制定數位廣告策略的五大關鍵因素:受眾篩選、廣告點擊意願、線上即時競價、數位廣告平台、廣告成效評估。希冀本研究能讓廣告主掌握數位廣告成功之道,在適當的時機選擇適當的數位平台,達到精準控管廣告成本,銷售長紅的廣告終極目標。
