Question 2

What is ad stacking in programmatic advertising fraud?

Accepted Answer

Placing multiple ads on top of each other so only the top ad is visible while all ads record impressions

Ad stacking involves layering multiple ads in a single ad slot so only the top ad is visible to users, yet all stacked ads register impressions, resulting in fraudulent billing for non-viewable placements.

Question 3

What is pixel stuffing in the context of ad fraud?

Accepted Answer

Hiding an ad in a 1x1 pixel frame so it is technically served but never seen by users

Pixel stuffing involves serving an ad in a 1x1 pixel iframe that is invisible to users, allowing fraudulent publishers to generate impressions without any genuine ad exposure.
