While advertising presents a reason to buy a product, sales promotion offers a short-term incentive to purchase. Sales promotions often attract brand switchers (those who are not loyal to a specific brand) who are looking primarily for low price and good value. Thus, especially in markets where brands are highly similar, sales promotions can cause a short-term increase in sales but little permanent gain in market share. Alternatively, in markets where brands are quite dissimilar, sales promotions can alter market shares more permanently. The use of promotions rose considerably during the late 20th century. This was due to a number of factors within companies, including an increased sophistication in sales promotion techniques and greater pressure to increase sales. Several market factors also fostered this increase, including a rise in the number of brands (especially similar ones) and a decrease in the efficiency of traditional advertising due to increasingly fractionated consumer markets.

Public relations, in contrast to advertising and sales promotion, generally involves less commercialized modes of communication. Its primary purpose is to disseminate information and opinion to groups and individuals who have an actual or potential impact on a company’s ability to achieve its objectives. In addition, public relations specialists are responsible for monitoring these individuals and groups and for maintaining good relationships with them. One of their key activities is to work with news and information media to ensure appropriate coverage of the company’s activities and products. Public relations specialists create publicity by arranging press conferences, contests, meetings, and other events that will draw attention to a company’s products or services. Another public relations responsibility is crisis management—that is, handling situations in which public awareness of a particular issue may dramatically and negatively impact the company’s ability to achieve its goals. For example, when it was discovered that some bottles of Perrier sparkling water might have been tainted by a harmful chemical, Source Perrier, SA’s public relations team, had to ensure that the general consuming public did not thereafter automatically associate Perrier with tainted water. Other public relations activities include lobbying, advising management about public issues, and planning community events.

Because public relations does not always seek to impact sales or profitability directly, it is sometimes seen as serving a function that is separate from marketing. However, some companies recognize that public relations can work in conjunction with other marketing activities to facilitate the exchange process directly and indirectly. These organizations have established marketing public relations departments to directly support corporate and product promotion and image management.

Companies have typically hired different agencies to help in the development of advertising, sales promotion, and publicity ideas. However, this often results in a lack of coordination between elements of the promotion mix. When components of the mix are not all in harmony, a confusing message may be sent to consumers. For example, a television advertisement for an automobile may emphasize the car’s exclusivity and luxury, while a Web-site advertisement may stress rebates and sales, clashing with this image of exclusivity. Alternatively, by integrating the marketing elements, a company can more efficiently utilize its resources. Instead of individually managing four or five different promotion processes, the company manages only one. In addition, promotion expenditures are likely to be better allocated, because differences among promotion tools become more explicit. This reasoning has led to integrated marketing communications, in which all promotional tools are considered to be part of the same effort, and each tool receives full consideration in terms of its cost and effectiveness.

No marketing process, even the most carefully developed, is guaranteed to result in maximum benefit for a company. In addition, because every market is changing constantly, a strategy that is effective today may not be effective in the future. It is important to evaluate a marketing program periodically to be sure that it is continuing to achieve its objectives.

There are four types of marketing control, each of which has a different purpose: annual-plan control, profitability control, efficiency control, and strategic control.

The basis of annual-plan control is managerial objectives—that is to say, specific goals, such as sales and profitability, that are established on a monthly or quarterly basis. Organizations use five tools to monitor plan performance. The first is sales analysis, in which sales goals are compared with actual sales and discrepancies are explained or accounted for. A second tool is market-share analysis, which compares a company’s sales with those of its competitors. Companies can express their market share in a number of ways, by comparing their own sales to total market sales, sales within the market segment, or sales of the segment’s top competitors. Third, marketing expense-to-sales analysis gauges how much a company spends to achieve its sales goals. The ratio of marketing expenses to sales is expected to fluctuate, and companies usually establish an acceptable range for this ratio. In contrast, financial analysis estimates such expenses (along with others) from a corporate perspective. This includes a comparison of profits to sales (profit margin), sales to assets (asset turnover), profits to assets (return on assets), assets to worth (financial leverage), and, finally, profits to worth (return on net worth). Finally, companies measure customer satisfaction as a means of tracking goal achievement. Analyses of this kind are generally less quantitative than those described above and may include complaint and suggestion systems, customer satisfaction surveys, and careful analysis of reasons why customers switch to a competitor’s product.

Profitability control and efficiency control allow a company to closely monitor its sales, profits, and expenditures. Profitability control demonstrates the relative profit-earning capacity of a company’s different products and consumer groups. Companies are frequently surprised to find that a small percentage of their products and customers contribute to a large percentage of their profits. This knowledge helps a company allocate its resources and effort.

Efficiency control involves micro-level analysis of the various elements of the marketing mix, including sales force, advertising, sales promotion, and distribution. For example, to understand its sales-force efficiency, a company may keep track of how many sales calls a representative makes each day, how long each call lasts, and how much each call costs and generates in revenue. This type of analysis highlights areas in which companies can manage their marketing efforts in a more productive and cost-effective manner.

Strategic control processes allow managers to evaluate a company’s marketing program from a critical long-term perspective. This involves a detailed and objective analysis of a company’s organization and its ability to maximize its strengths and market opportunities. Companies can use two types of strategic control tools. The first, which a company uses to evaluate itself, is called a marketing-effectiveness rating review. In order to rate its own marketing effectiveness, a company examines its customer philosophy, the adequacy of its marketing information, and the efficiency of its marketing operations. It will also closely evaluate the strength of its marketing strategy and the integration of its marketing tactics.

The second evaluation tool is known as a marketing audit. This is a comprehensive, systematic, independent, and periodic analysis that a company uses to examine its strengths in relation to its current and potential market(s). Such an analysis is comprehensive because it covers all aspects of the marketing climate (unlike a functional audit, which analyzes one marketing activity), looking at both macro-environment factors (demographic, economic, ecological, technological, political, and cultural) and micro- or task-environment factors (markets, customers, competitors, distributors, dealers, suppliers, facilitators, and publics). The audit includes analyses of the company’s marketing strategy, marketing organization, marketing systems, and marketing productivity. It must be systematic in order to provide concrete conclusions based on these analyses. To ensure objectivity, a marketing audit is best done by a person, department, or organization that is independent of the company or marketing program. Marketing audits should be done not only when the value of a company’s current marketing plan is in question; they must be done periodically in order to isolate and solve problems before they arise.
