Effects of link placements in email newsletters on their click-through rate

Firms adopting email marketing strategy often complain about low click-through rate (CTR). Scarcity of attention in this digital economy requires including psychological aspects of consumer behavior into the design considerations of digital contents. In this study, we propose differential effects of link placements in email newsletter on their CTR. We explain the observed effects of link placements on CTR drawing concepts from psychology and visual heuristics. The empirical analysis confirms that when it comes to clicking on the links of a newsletter, the click-through follows a U-pattern, i.e. as users traverse the links placed on a U-path their responsiveness decreases gradually. Thus, links placed in the left region of an email newsletter have higher impact than those placed in the right region with links in the top-left region having highest impact. Insights gained from this study can be used in the design consideration of email newsletters.

The Advisor-SMF Client Relationship: Impact,Satisfaction and Commitment

This paper investigates the relationship between the type of business advisors used by SMEs and the level of impact and satisfaction a SME receives. The role of other influences, such as the intensity and cost of the service, and the level of commitment to an advisor by the client are also investigated. A structural equation path model is estimated from survey information for SMEs in Britain. The analysis shows that customer impact, satisfaction and re-use intentions are related to the character of the firm (particularly its size), the intensity and cost of services, but is only marginally influenced by the geographical distance between advisor and client. Affective commitment, measured by the level of the ‘trust’ of the advisor by the client, is shown not to be significant, except for public sector and business association suppliers. The importance of trust to these suppliers, despite the low satisfaction levels they achieve, is argued to be incompatible with attempts to charge fees, as has been sought for the government network of Business Link. Both business associations and public sector support bodies therefore have severe limitations in combining their broader roles with a commercially- based fee-based income strategy.

在价值理论研究中要破除"上纲"情结--兼评当前关于劳动价值论的大讨论

在分配制度中,把按劳分配和按生产要素分配结合起来,的确遇到“劳动价值论一元论”的理论障碍;其持论者是对马克思、恩格斯生产力理论的误解或曲解,体现着一种不合时宜的“阶级斗争为纲”思维方式或“上纲”情结;在现实中,只有坚持生产力决定性原理,并加进生产力的变动与对伦理价值主导性的考虑,才能对现实问题在理论层面作出实事求是的分析。
