A flyer is a single-page printed or digital advertisement used for promoting events, products, services, or special offers. It is designed to quickly grab attention with bold headlines, eye-catching visuals, and concise information. Flyers are typically distributed in public places, handed out directly, or shared online to reach a wide audience. They come in various sizes, with A5 and A4 being the most common. Flyers are cost-effective marketing tools used for business promotions, event announcements, sales, and awareness campaigns.
