What are the 2 most common ways businesses advertise?

The two most common ways businesses advertise are through digital marketing and traditional media. Digital marketing includes online methods such as social media advertising, search engine optimization (SEO), and email campaigns, allowing for targeted outreach and engagement. Traditional media encompasses print ads, television commercials, and radio spots, which can reach a broad audience but often lack the targeting capabilities of digital methods. Both approaches can be effective depending on the business's goals and target audience.
