An advertising agency is looking for any company that wants to be made public to consumers about the products or services it offers. Nowadays, competition in every field is extremely high, and finding an advertising agency is profitable for every business.

Advertisers were originally hired to boost demand for products not paid by manufacturers. Consequently, advertising agencies stimulate the demand for all products, and the methods are much more advanced. Generally, an advertising agency is looking to increase the sales of a product or service. Although this is the work of the marketing departments of companies, advertising agencies often design and execute promotional campaigns to impose products that are soon placed on the market or not sufficiently demanded by consumers.

Advertising agencies are often used to reinforce or change the image of a brand. For example, the Chanel brand has launched an advertising campaign to discourage sales from a lower social group, and its long-lasting profits are achieved by maintaining a good image from an advertising agency.
