The fast growth of digital media and online platforms has completely changed the way companies promote their products and services. Today, businesses use social media, websites, mobile apps, influencer marketing, and online advertisements to reach millions of consumers quickly. Although digital marketing provides many benefits, it has also increased the number of misleading and deceptive advertisements seen by people every day. Many advertisements make false promises, hide important information, exaggerate product benefits, or use influencers without clearly mentioning paid promotions. Such practices can confuse consumers and influence them to make wrong purchasing decisions. This paper studies the problem of misleading advertisements in digital platforms and examines the laws and regulations made to protect consumers. It focuses on important legal frameworks such as the Consumer Protection Act, 2019 in India, the guidelines of the Federal Trade Commission in the United States, and the Digital Services Act in the European Union. The study is based completely on secondary data collected from research papers, government reports, legal documents, and regulatory studies published between 2019 and 2024. The paper explains how practices such as false advertising, dark patterns, hidden sponsorships, and algorithm-based targeting can harm consumers financially and emotionally. It also highlights the difficulties faced by governments in controlling misleading advertisements across different countries. Finally, the study suggests practical solutions like stronger laws, better monitoring systems, stricter penalties, and increased consumer awareness to improve accountability in digital advertising.
