Step-by-step explanation:
The element of the promotional mix that is most effective in building up buyers' preferences, convictions, and actions at certain stages of the buying process is advertising.
Advertising plays a crucial role in shaping buyers' preferences by creating awareness, generating interest, and influencing attitudes towards a product or service. Through advertising, companies can communicate the unique features, benefits, and value proposition of their offerings, which can help build positive perceptions in the minds of buyers.
For example, a company may use TV commercials, online ads, social media promotions, or print advertisements to highlight the qualities and advantages of their product, evoke emotions, and persuade buyers to choose their brand over competitors. By strategically conveying compelling messages and visuals, advertising can effectively influence buyers' preferences, convictions, and ultimately, their actions.
