The most obvious advantage of marketing internationally is the expansion of a company's market. Expanding the places where a company does business and advertises its products and services opens up a larger customer base and potentially greater profit margins. While small businesses may find that marketing internationally is cost prohibitive, technology such as social media and online newspapers and advertising services have made the process of international marketing even more attractive. Customers can now buy from virtually anywhere in the world via the Internet, making market expansion through international marketing a highly useful skill for businesses to master.
