1. Topic : Evaluating Retail Trade Areas for convenience Stores. Description of historical of marketing background. 2.Topic : Signaling Quality in an E-Commerce Environment: The Case of an Emerging E-Grocery Sector More than just a potential economic enhancement for food marketing, our research spanning 36 months in 2001, 2002, and 2004 identifies that E-Grocery enterprises present unique communication challenges. It is easy to tell online customers the quality of a book or a music CD. However, conveying the ripeness of a banana, the marbling in a steak, or even the meaning of the “best by” date on a gallon of milk are significant challenges for online marketers. In a traditional grocery store, meat, poultry, seafood, produce, and other highvalue food items depend on organoleptic (sight, smell, touch) experiences to guide selection. To date, little research has evaluated how well those sensory experiences of product quality attributes are communicated online. Leading E-Grocers are experimenting with ways they can communicate sensory attributes online and cater to the emotional connection consumers have with their food. Likewise, smaller direct-market food sellers (including farm-based meat and produce markets and similar rural enterprises) are selling products with pronounced organoleptic values and need benchmarks for the consumer value of better online signals of the quality of the perishable products they market. E-Grocery activity and other online communications dealing with qualitycentric and/or sensory-based products (e.g., scents, collectables sold on auction sites, or medical/science information) require a new understanding of how to reach the target market. Marketers, especially marketing communication professionals, are faced with a new and rapidly evolving set of tools–and limited research-based guidance on how to effectively use such tools or even evaluate their effectiveness.
