Why VPN and proxy abuse costs advertisers so much
The damage goes beyond wasted clicks. VPN and proxy abuse corrupts your bidding data, distorts your audiences, and erodes the performance of every campaign it touches.
VPN and proxy abuse occurs when invalid traffic is routed through virtual private networks or anonymous proxy servers to disguise its true origin. Advertisers who geo-target their campaigns are particularly exposed, as bad actors use VPNs to appear as if they are clicking from within the target geography while actually operating from anywhere in the world.
Beyond geo-targeting abuse, VPN and proxy abuse is used to circumvent IP-based frequency caps, allowing the same bad actor to click your ads repeatedly without triggering volume-based detection. It also enables coordinated operations to hide the centralized source of their traffic, making it appear to come from thousands of different legitimate users.

How Tapper detects and blocks VPN and proxy abuse
Real-time detection and blocking across all your ad platforms, with no engineering required.
01
Tapper maintains a continuously updated database of known VPN providers, proxy services, and anonymizing networks, cross-referenced against every click your campaigns receive.
02
Rather than blanket-blocking all VPN traffic, Tapper scores each session holistically - a legitimate user on a corporate VPN behaves very differently from a bot operator hiding behind one.
03
Only traffic confirmed as invalid is blocked, with a 0.1% false positive rate ensuring genuine users are never excluded from your campaigns.

higher conversion rate
“When we take low-quality traffic out of the funnel before it reaches the algorithm, the campaign optimizes against cleaner signals and the efficiency comes through quickly. For AMA Nissan, that was a 40% lift in conversion rate and a lower CPA on Google, with nothing else in the setup changing. That is the kind of result we want to offer clients as a matter of course.”

“We've been using Tapper for over a year now, and it has become a core part of how we run paid media. Invalid traffic was always something we knew existed but couldn't really act on. Tapper changed that. We're now saving up to $50K per year, and on PureSquare specifically, we saw around a 20% decrease in CPA. Based on these results, we decided to roll it out across other ventures under Disrupt as well.”
