An ad, short for advertisement, is a paid marketing tool that enables businesses to promote their products and services to a broad audience. Advertisements come in various forms, including television commercials, pamphlets, billboards, and online ads, each offering distinct advantages depending on the target audience and marketing objectives.

For instance, television commercials can reach a wide audience during peak viewing times, while online ads can be tailored to specific demographics using data analytics.

Online businesses, in particular, leverage ad campaigns to enhance brand awareness and engage potential customers. These campaigns are strategically designed to appear on platforms where their target audiences are most active, such as social media, search engines, and websites.
