What does the term "ad fraud" refer to?

The term "ad fraud" encompasses a variety of deceptive practices that manipulate and inflate ad performance metrics, leading to a misrepresentation of how well an advertisement is actually performing. This includes activities such as generating fake clicks or impressions, using bots to mimic human engagement, and other unethical tactics aimed at artificially increasing the visibility or interaction with an ad.

When advertisers do not receive accurate data about their campaigns, they are unable to make informed decisions, allocate budgets correctly, or optimize their strategies effectively. This ultimately results in wasted resources and undermines the trust in digital advertising systems.

Other options may involve aspects of advertising but do not encapsulate the essence of ad fraud as effectively as the correct choice. For instance, the creation of fake adverts might be misleading, but it does not capture the broader scope of fraudulent metrics manipulation that defines ad fraud. Similarly, overestimation of audience reach and errors in ad delivery systems may impact campaign effectiveness but are not inherently fraudulent in nature as they do not involve deceptive intent.
