What Is Ad Fraud?
Ad fraud refers to any activity that generates illegitimate impressions, clicks, or conversions in digital advertising. It costs the industry billions annually and directly eats into advertiser budgets.
Types of Ad Fraud
| Fraud Type | Description | Impact |
|---|---|---|
| Bot traffic | Automated bots generate fake impressions | Wasted impressions |
| Click fraud | Bots or humans click ads without intent | Wasted CPC spend |
| Domain spoofing | Low-quality sites disguised as premium publishers | Poor brand safety |
| Ad stacking | Multiple ads stacked in one placement | Invisible impressions charged |
| Cookie stuffing | Fake affiliate conversions via background cookies | False CPA payouts |
| Pixel stuffing | 1×1 pixel ads generate impressions | Fraudulent CPM charges |
How to Detect Ad Fraud
- Unusually high impressions, zero conversions — bot traffic signal
- CTR spikes from specific sources — click farm activity
- Traffic from unexpected GEOs — proxy/VPN traffic
- Very low time-on-site — bots don’t read pages
- Same IP generating many clicks — manual click fraud

Frequently Asked Questions
How much of digital ad spend is lost to fraud?
Industry estimates put ad fraud losses at $80–$100 billion globally per year. For popunder campaigns, choosing quality networks reduces but doesn’t eliminate fraud exposure.
How do I know if my popunder traffic is fraudulent?
Look for zero conversions despite high impression volume, extremely low session duration in your analytics, and traffic from unusual GEO combinations.
Is Adsailor traffic fraud-free?
No traffic network can guarantee 100% fraud-free delivery. Adsailor uses multi-layer detection to minimize IVT, but advertisers should always complement network-side protection with their own tracking.
