Advertising has special functions and uses in sales promotion:

1. Advertising is the largest, fastest and most extensive information dissemination medium. Through advertising, enterprises or companies can convey information about the characteristics, functions, uses and suppliers of products and services to consumers, communicate with producers and demanders, attract consumers' attention and interest, and promote purchases.

2. Advertising can stimulate and induce consumption. The consumer's demand for a product is often a potential demand, which sometimes contradicts the actual purchase behavior. The visual and sensory image and inducement caused by advertisements can often arouse consumers' realistic desire to buy. Some new products that are cheap and marketable are difficult to open the market because they are not known to consumers, and once they are advertised, consumers will buy them one after another.

3. Advertising can better introduce product knowledge and guide consumption. Through advertisements, the performance, quality, use, maintenance and installation of products are comprehensively introduced, and their doubts and worries about maintenance, maintenance and installation are eliminated, thus generating a desire to buy.
