Impression fraud is a subset of the broader term 'ad fraud,' which encompasses various deceptive practices intended to exploit the online advertising ecosystem. Ad fraud includes activities like click fraud, conversion fraud, and more. By understanding impression fraud, one can better appreciate the complexities and scale of ad fraud.

Two common techniques used in impression fraud are ad stacking and bot traffic. Ad stacking involves placing multiple ads on top of each other in a single ad placement, so only the top ad is visible while the others generate impressions without being seen. Bot traffic refers to the use of automated programs to simulate human visitors, generating fake impressions en masse. Both techniques deceive advertisers into paying for non-existent views.

Click spamming and click farms are related forms of ad fraud that share similarities with impression fraud. Click spamming involves generating fake clicks on ads, while click farms employ low-paid workers to manually click on ads. Both practices, like impression fraud, aim to inflate advertising metrics dishonestly.

Invalid Traffic (IVT) is a broader category that includes any non-genuine traffic, encompassing both impression fraud and other deceptive practices. IVT can severely impact the accuracy of performance data and the return on investment for advertisers. Managing IVT is crucial for maintaining the integrity of digital marketing efforts.

To combat impression fraud and related jargons, advertisers and publishers must employ advanced detection tools and adopt best practices. Using machine learning algorithms, real-time monitoring, and collaboration with industry watchdogs are some of the strategies to identify and mitigate fraudulent activities. Education and awareness among all stakeholders are also key in the fight against ad fraud.
