The Digital Markets Act (DMA) is a European law aimed at creating a fairer online environment by regulating "gatekeepers" - major internet companies with significant market power. The primary goal of the DMA is to limit the dominance of tech giants in the digital marketing space, providing a level playing field for smaller businesses and promoting transparency and fairness. Key implications include expanded app distribution freedom, fair sales terms, and greater control over data access, allowing marketers to make data-driven decisions, innovate with interoperability, and achieve fair rankings and visibility. Non-compliance with the DMA will result in harsh penalties, including fines of up to 20% of a company's total global turnover. The law also empowers consumers by giving them more choices, better services, and control over their data.
