Digital advertising is significantly undermined by click fraud, a deceptive tactic that artificially inflates ad click metrics through automated bots or hired human clickers. This fraudulent activity not only depletes advertising budgets but also corrupts campaign performance data, leading marketers to make misguided strategic decisions based on falsified engagement metrics. The financial impact of click fraud on the global digital advertising ecosystem amounts to billions of dollars annually, creating an urgent challenge for advertisers seeking accurate performance measurement and return on investment.
