Good advertising requires competent personnel including a number of specialists to enable it thrive in the ever dynamic and competitive business environment. In our efforts to highlight the impact on the sales volume of the company's products a survey study of was carried out. Questionnaires were administered on 107 staff of the organization to determine the impact of advertising on the marketing of the company's products. The data obtained were presented using tables and the analysis was done using simple percentage and descriptive methods, while chi-square was used to test the hypothesis. Results of the findings indicate there is a positive relationship between advertising and sales volume of the company and that advertising has impacted on the marketing of the company's products. In view of this the researcher recommended that due to the competitive nature of the industry the marketing manager must develop and formulate marketing programmes that will satisfy the needs of the consumers. Also, since other service producers have similar advertising messages, it is recommended that for a more distinguished and effective response from the customer, other forms of advert should be used. Regular and consistent up-to-date training on product information should be given to the advertising agency so that they will have the current knowledge and skills to handle the adverts and also to ensure that product information is being emphasized so as to enlighten the customers.
