Advertising is the action of drawing public attention to something, usually through some kind of payment method. It can be used in a variety of ways, from print media to product placement, and is essential for any business to survive in a free-market economy. Examples of successful advertising campaigns include Absolut's print marketing campaign, Nike's “Just Do It” campaign, Google's annual video, and Coca-Cola's “I'd Like to Buy the World a Coke” commercial. Native advertising is also becoming increasingly popular.
To maximize the effectiveness of an advertising campaign, it is important to understand the size and composition of its audience. By understanding these factors, businesses can create campaigns that are tailored to their target audience and maximize conversions.
