在這個新媒體服務竄起的時代，許多中小型商家卻難以充分利用新媒體在顧客生命週期(customer life cycle)管理的過程中提升顧客參與行為。而在所有新媒體當中，搜尋引擎又被認為是獲取和發展新顧客最有效的方式之一。因此本研究在搜尋引擎的基礎上提出了一個藉由合作營銷活動最大化顧客參與的新架構。 我們利用在顧客參與平台上建構反向鏈結以及長尾關鍵字服務來實現我們的架構。通過針對中小型商家和顧客的控制實驗，我們驗證了該架構的可用性和效果。我們發現兩種服務對於增進網路能見度以及搜尋精準度都有明顯的提升。而高網路能見度及高搜尋精準度可以幫助中小型商家提升顧客參與行為，不論是在顧客參與平台或是其官方網站。因此本研究認為中小型商家可以利用顧客參與平台上的服務來建立合作營銷活動，以促進顧客參與行為。在這個過程中，不僅有利於顧客對於品牌態度的建立也有助於其轉變為中小型商家忠實顧客的可能性。 / Facing the fast-changing trend of service economy upon new media, most small and medium enterprises (SMEs) don’t have the capability to utilize new media to stimulate customer engagement behavior (CEB) through customer life cycle (acquisition, development, and retention). In all the new media, search engine is the most helpful way on acquiring and developing new customers, thus we propose a new framework based on search engine to maximizing the CEB through brand alliance-based campaign (which is a popular marketing strategy for SMEs to acquire new customers). According to our framework, the study implements two search engine services including inlink building service and long tail keyword service on engagement site. With conducting controlled experiments toward SMEs and customers, we testify our system by SMEs and the effects of services toward the customers. We find that inlink building service and long tail keyword service increase both on high search targetability and web visibility for customers. With high web visibility and search targeatbiliy, CEB can be stimulated on engagement site and also target sites of SMEs. Thus we conclude that SMEs can use brand alliance-based campaign with our services as a trigger to stimulate CEB. With increment on engagement behavior, customer’s brand attitudes then increase and in the end become loyal customers to the SMEs.
