Therefore, as an enterprise committed to terminal promotion, we should not only pay attention to the construction and maintenance of terminals, but also conduct market supervision on a regular basis. The Significance of Market Supervision Market supervision is very important and essential in the whole marketing work. However, in order to save costs, some small and medium-sized enterprises have not established a supervision mechanism. Some enterprises that have set up supervisory positions are often ineffective. When they feel that there is a problem in a certain market, they quickly send people to that market to supervise it, instead of turning the supervision behavior into a system and carrying it out in a planned and step-by-step manner. Market supervision The role of market supervision is to check the results of business representatives' visits to the terminal, which is a powerful supplement to help business representatives find and solve problems, and also to cooperate with salesmen to realize collaborative visits to the main person in charge of the terminal and decision makers. At the same time, the marketing director is also responsible for the inspection of terminal operation, including hard terminal and soft terminal inspection. Hard terminal inspection mainly refers to product inspection and publicity materials inspection. Soft terminal inspection includes entrance observation, assistant orientation test, product knowledge test, publicity material inspection, assistant random inquiry and detailed inquiry after identification. To carry out promotion supervision correctly, we should grasp the following links in our work: information collection, collecting the information of major competitors or terminals covered by some local big businesses; Understand the characteristics and competitive advantages of similar products; Understand the reasons why similar products sell well; Understand the ability of distributors and distributors to cover their own products and the sales data of terminals; Understand the industry's evaluation and reputation of the terminal, and understand the relevant statistics in the industry; Understand the terminal on the spot, including area, number of salespersons, geographical location, estimation of people flow, surrounding community status, consumption level, etc. Generally, an enterprise has multiple products, and new products are constantly being introduced to the market. However, it is difficult for promoters to receive product knowledge training at the same time. At the same time, due to the high mobility of promoters, market supervisors need to give special guidance on a regular basis to help promoters better promote their products.
