Click farm fraud on open exchange programmatic campaigns
Click farms use real devices operated at scale to generate fraudulent interactions on open exchange inventory, defeating device-signal fraud filters and inflating your CPM and CPC costs.

Click farms on open exchange exploit minimal publisher vetting to generate revenue at your expense
The open exchange model pays publishers a revenue share for each click and impression their inventory generates. This creates a straightforward financial incentive for fraudulent publishers: the more click farm traffic they route through their inventory, the more they earn at your expense. Click farms use real consumer devices, managed by low-wage workers or automated device management software, to generate fraudulent interactions that are almost indistinguishable from genuine user behaviour at the device signal level. Standard IVT filters, which rely on known bot fingerprints and datacenter IP ranges, cannot detect this type of fraud.
The open exchange makes click farms particularly effective because publisher vetting is minimal. Fraudulent operators can join the bid stream, serve low-quality inventory, and route click farm traffic without the scrutiny that private marketplace or programmatic guaranteed deals would require. Your display campaigns show rising click-through rates and engagement metrics, but conversions remain flat because no real buyer is behind any interaction. Your DSP optimises toward these fraudulent engagement signals, pushing spend toward inventory and audience segments associated with click farm activity.

“When we take low-quality traffic out of the funnel before it reaches the algorithm, the campaign optimises 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.”

Frequently asked questions
Everything about click farms on Display & Programmatic open exchange.
Open exchange inventory requires minimal vetting for publishers to access the bid stream. Fraudulent operators can join exchanges, declare inventory across broad categories, and route click farm traffic through their placements with limited scrutiny. Private marketplace deals require direct publisher relationships and vetting that make click farm operations far harder to sustain.
Click farms inflate your click-through rate and engagement metrics while delivering zero real audience value. Your DSP interprets the fraudulent engagement signals as genuine audience interest and adjusts bidding and targeting accordingly, pushing your open exchange spend toward inventory sources and audience clusters associated with click farm activity. Conversions remain flat while costs rise.
Tapper provides per-publisher fraud scoring across your open exchange buy, identifying the inventory sources generating click farm traffic. This data lets you build targeted suppression lists and, where applicable, submit evidence to your DSP or exchange for credit review. Tapper surfaces the inventory-level data that your DSP reporting aggregates away.
