(marketing research definition) A coordinated collection of data, system tools, and techniques with supporting software and hardware by which an organization gathers and interprets relevant information from business and the environment and turns it into a basis for making management decisions. 2. (models definition) A system, usually based on a model and computer software package, that describes the implications of specific marketing decisions and/or recommends specific marketing actions, using a set of input information.

The information can consist of primary information (e.g., sales and cost information from company records, or subjective judgments by managers about the likely impact of increased advertising spending) and/or secondary information (e.g., sales of competitors' products from a syndicated database constructed via store audits). An important aspect of many decision support systems is the facilitation of "what if" analyses; i.e., the sensitivity of optimal marketing strategy to the assumptions in the input information.

                                      Default PageThe default page setting should be set to whatever the default (or index) page is in your site's directories. Usually, this will be 'index.html', but on Windows IIS servers, it is often 'Default.htm' or 'index.htm'. This information allows Google Analytics to reconcile log entries such as 'http://www.example.com/' and 'http://www.example.com/index.html', which are in fact the same page. Without the Default Page information entered correctly, these would be reported as two distinct pages. Only a single default page should be specified. Source: Lazworld

Diffusion models in marketing often are applied to the adoption of a new product, or the exposure of potential customers to some in-formation about a product (e.g., an advertising message). Numerous specific mathematical formulations have been applied to diffusion processes, and these are reviewed by Lilien and Kotler (1983 Chapter 19) and Mahajan and Wind (1986). The most widely cited of these models was introduced to marketing by Bass (1969). It incorporates explicitly an innovation effect and an imitation effect. When both effects are present, the time path of adoption follows an S- shaped curve.

Over repeated occasions on which purchases are made from the product category, the set of brands chosen are assumed to follow the multinomial distribution for any given individual. The model also assumes that individuals differ from each other in their set of brand choice probabilities. These probabilities are taken to have a Dirichlet distribution across individuals. The Dirichlet is a parsimonious distribution for the set of brand choice probabilities: for n brands there are n Dirichlet distribution parameters; n - 1 of which indicate the average share of choices for each brand, and the nth indicating the amount of heterogeneity in preference across individuals. The model thus can be used to predict brand choice patterns exhibited over time by a set of individuals (Jeuland, Bass, and Wright 1980; Goodhardt, Ehrenberg, and Chatfield 1984).

Positive disconfirmation occurs when the product performs better than expected; negative disconfirmation occurs when the product performs worse than expected.

It can be distinguished from regular retailers only by its consistent emphasis upon discount prices and its self-designation as a discount store. Much of the distinctive character has disappeared with the development of other forms of mass-market retailing.

According to Bettman, if a product, brand, or alternative passes that standard for any attribute, it is accepted. The evaluation process yields groups of acceptable and unacceptable alternatives and hence the evaluation is derived rather than direct.

Specialized models have been developed, however, for specific distribution decisions such as site selection and logistics. Most of the gravitational site selection models follow Huff (1964), who developed a model in which the attraction of a site is proportional to the size of the retail center and inversely proportional to the customers' distance from the site. This model has been extended to incorporate not only size of retail site, but also image. These models are extensions of the Multiplicative Competitive Interaction model. Logistics-related optimization models have also been developed for warehouse locations and inventory management. Most of the models are based on mathematical programming or simulations.

The major classes of diversification are concentric, horizontal and conglomerate. Concentric diversification results in new product lines or services that have technological and/or marketing synergies with existing product lines, even though the products may appeal to a new customer group. Horizontal diversification occurs when the company acquires or develops new products that could appeal to its current customer groups even though those new products may be technologically unrelated to the existing product lines. Conglomerate diversification occurs when there is neither technological nor marketing synergy and requires reaching new customer groups.

For example, if a user is looking for trucks, then a dynamic landing page with information and pictures on multiple models and, possible, geographically localized dealerships might be served. The term truck would trigger a data dump into a web site template for all possible vehicles, that serves all truck-related information. Source: SEMPO

When the search query (for example, "hybrid cars") matches the defined parameter (for example, all brand of electric/gasoline passenger cars AND SUVs), then the associated term (hybrid) is plugged into the ad. Dynamic insertion makes the ad mirror exact terms used in the search query, creating very relevant ads. Source: SEMPO
