Impression fraud occurs when a digital advertisement is displayed to users without genuine engagement, often through automated bots or deceptive practices. This manipulation inflates the number of impressions, misleading advertisers about the effectiveness of their campaigns. Advertisers pay for these impressions, believing they are reaching real potential customers. However, the actual audience may be minimal or non-existent, resulting in wasted marketing budgets. Tools and technologies are being developed to combat impression fraud and ensure that advertisers receive accurate data about their ad performance.
