This document introduces online business and compares it to traditional marketing. Online marketing uses websites, domain names, content writers, search engine optimization, social media marketing, pay-per-click advertising, and email marketing to reach global customers with a low budget and high profit margins. In contrast, traditional marketing relies on physical locations, salespeople, printed materials, and local advertising, resulting in high overhead costs and low profit margins. The document encourages developing an online presence and digital marketing strategies to take advantage of the opportunities of online business.
