Online advertising has built a market of hundreds of billions of dollars and still continues to grow. With well developed techniques in big data storage, data mining and analytics, online advertising is able to reach targeted audiences e ctively. Real- time bidding refers to the buying and selling of online ad impressions through ad inventory auctions which occur in the time it takes a webpage to load. How to de- termine the bidding price and how to allocate the budget of advertising is the key to successful ad campaigns. Both of these aspects are fundamental to most campaign optimizations and we will introduce both of them in this thesis. For bidding price determination, we improved the estimation of CTR (Click Through Rate) (one of the most important factors of determining the bidding price) by using a re ned hierar- chical tree structure for the estimation. The result of the experiment and the A/B test showed our proposal can provide stable improvement. For budget allocation, we introduce SCO (Single Campaign Optimization) and CCO (Cross Campaign Opti- mization). SCO has been applied by our commercial partner while CCO needs more research. We will rst introduce the methods of SCO and then give our proposal about CCO. We modeled CCO as a LP (Linear Programming) problem as well as designed an e ective procedure to implement optimal impressions distribution. Our simulation showed our proposal can signi cantly increase global Gross Pro t (GP). / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

Since its creation, it has never been remodeled; and, faced with a scenario in which social media has increased its importance in developing digital marketing strategies, there was this theoretical gap. Therefore, this thesis "Brand Identity Prism: perspective for a model evolution", aims to: contribute academically to advances in digital marketing theories, expanding the knowledge to the formation of more solid strategies and provide practical suggestions to managers of digital marketing departments in the fashion industry, but also to other market segments. To achieve the proposed objectives, the literature review regarding this tool was carried out, as well as accessories concepts: Lovemarks and virtual brand communities. The research methodology used was the qualitative kind, with single case study research strategy, which was through the study of a French origin fashion brand, "Repetto Paris". The results showed that it is possible to suggest an advance in the current model of the Prism, given the reality in which the organizations are, of intense competition and of an increasing need of communication and relationship with the consumers via social media platforms / O Prisma de Identidade de Marca é uma ferramenta de análise que foi criada por Jean-Noël Kapferer em 1991, e, desde então, consiste em um instrumento de grande importância para as organizações. A contar de sua elaboração, não passou por mudanças; e, diante de um cenário no qual a gestão da marca nas plataformas de redes sociais tem aumentado sua importância na elaboração de estratégias de marketing digital, observou-se esta lacuna teórica. Por isso, a presente tese “Prisma de Identidade de Marca: perspectiva para evolução do modelo”, tem por objetivos: contribuir academicamente para avanços nas teorias de marketing digital, ampliando o conhecimento para a formação de estratégias mais sólidas, bem como fornecer sugestões práticas aos gestores de departamentos de marketing digital no setor de moda, mas também aos demais segmentos de mercado. Para atingir os objetivos propostos, foi realizada a revisão da literatura no que se refere a esta ferramenta, assim como os conceitos complementares: Lovemarks e Comunidades Virtuais de Marca. A metodologia de pesquisa utilizada foi do tipo qualitativa, com estratégia de investigação de estudo de caso único, que se deu por meio do estudo da marca de moda de origem francesa, “Repetto Paris”. Os resultados encontrados demonstraram que é possível sugerir um avanço no modelo atual do Prisma, considerando-se a realidade na qual as organizações se encontram, de intensa concorrência e de necessidade cada vez maior de comunicação e relacionamento com os consumidores via plataformas de redes sociais

Thesis by publication. / Thesis (PhD) -- Macquarie University, Macquarie Graduate School of Management, 2008. / Bibliography: leaves 124-133. / Introduction - Literature review -- Online word-of-mouth: a comparison of American and Chinese discussion boards -- Electronic word-of-mouth: a comparison of stated and revealed behaviour on electronic discussion boards -- A cross-cultural comparison of electronic word-of-mouth and country-of-origin effects -- Conclusion. / The growth of electronic discussion boards has enabled consumers from different cultures to communicate with people of similar interests. Through this online channel, marketing concepts such as word-of-mouth (WOM) and country-of-origin (CoO) effects have the potential to become more important because of the potentially large number of participants involved. The US and China, being the largest and second-largest online population in the world respectively, are ideal countries to investigate the frequency and extent of these marketing concepts. --The thesis consists of three separate but inter-related papers which have been published in journals or have been accepted for publication. Each paper builds on the one before and analyses different aspects of online consumer behaviour such as information-giving, information-seeking and the CoO statements made by participants of discussion boards. By examining and comparing the frequency and content of discussion postings on discussion boards within US and China based websites, the thesis makes a comparison of the information-giving and information-seeking behaviour of the discussants and also looks at the extent and the content of CoO statements made. Online observation of discussion postings from six different discussion boards (three each from the US and China) was conducted over two 90-day period in 2004 and 2005 and a total of 5,993 discussion postings were downloaded for analysis. In addition, an online survey of 214 participants was conducted to compare the stated and actual (or "revealed") behaviour of discussants on the US and China based discussion boards. -- Overall, the findings indicate consistent differences over a 12-month period in the bahaviour of the US and Chinese discussants. The US discussants were found to provide more information than their Chinese counterparts while the Chinese discussants exhibited more information-seeking bahaviour on the discussion boards. The findings also indicate that the Chinese discussants demonstrated more negative CoO statements and these statements were observed to be related to Japan and/or brands that originated from Japan. The findings suggest that such negative CoO statements can increase rapidly online and it appears that the negative sentiments by the Chinese were apparently unrelated to product quality; instead they appear to have been predominantly associated with war related animosity. -- These findings have important implications for marketers selling to the Chinese as discussion boards appear to be more important as a source of information for the Chinese than the Americans. Also, given that the Chinese discussants demonstrated a high level of negative CoO statements relating to products from Japan, marketers selling Japanese products to the Chinese must understand the underlying issues related to these negativeCoO statements and take steps to prevent non-purchase of Japanese products. / Mode of access: World Wide Web. / vii, 133 leaves ill
