Competitor click fraud on open exchange programmatic campaigns
Rivals exploit the RTB open exchange to flood your display campaigns with coordinated invalid clicks, exhausting your budgets and corrupting the DSP signals that govern your spend.
Trusted by leading brands worldwide
The open exchange gives competitors low-cost, high-impact access to your programmatic placements
On the open exchange, any DSP buyer can target the same inventory and audiences you are bidding on. Competitors who understand programmatic buying mechanics can direct bot networks or click farm operations toward your display creatives, inflating your click costs and burning through your daily budget before peak audience hours. Because bid streams process millions of transactions per second with no human review, competitor-originated invalid traffic blends into genuine engagement signals and is almost impossible to identify without dedicated monitoring.
The downstream effect compounds the immediate budget loss. Your DSP reads the inflated click signals as genuine audience interest and adjusts its bidding, creative delivery, and targeting parameters accordingly. Frequency caps are exhausted by invalid interactions, reducing reach against real audiences. CPMs rise as the algorithm chases the fake engagement patterns. Tapper monitors impression and click events across your entire open exchange buy, isolating competitor-origin invalid traffic and removing it from the data your DSP uses to optimise.
How Tapper stops competitor clicks on Display open exchange
Three steps from connection to clean campaign data, no engineering required.
01
Connect your DSP to Tapper
Tapper integrates with your demand-side platform and begins monitoring every impression and click event across your open exchange buys, creating a baseline of genuine engagement patterns.
02
Competitor traffic patterns flagged in the bid stream
IP reputation analysis, device fingerprinting, and velocity profiling identify click patterns consistent with competitor or proxy-driven interference, flagging them before they enter your campaign learning data.
03
DSP optimisation data kept clean
Competitor-origin invalid clicks are excluded from all performance reporting, so your DSP continues to optimise toward genuine audience signals rather than artificially inflated engagement from rival interference.

“Tapper played a key role in improving the efficiency of Du's performance marketing activity by addressing traffic quality issues within campaigns. Following implementation, Du achieved a 13% reduction in CPA and an 8.6% increase in order rate, demonstrating a clear improvement in conversion quality and overall campaign effectiveness.”
Joseph Elbcherrawy
Client Leadership Director, Mindshare, a WPP Media Brand
“During our Tapper trial for INFINITI, we uncovered low-quality traffic that wasn't visible inside the platforms. Removing it delivered a 14% uplift in conversions and an 11.4% reduction in CPA - a meaningful efficiency gain for INFINITI's 2026 growth plans.”
David Barnes
Data & Technology Lead, Omnicom Group
“With Tapper's protection we were able to identify and block invalid clicks in real time. The impact was immediate as our cost per acquisition dropped by 30% and ROAS improved significantly. More importantly, Tapper gives us the confidence that our campaigns are reaching genuine customers, which makes it truly invaluable.”
Dimitris Bakas
Senior Performance Marketing, Public Group
“We started using Tapper to get better visibility on where our clicks were coming from, and ended up cutting wasted spend by over 12%. The performance uplift was clear, and for the first time, we could trust the numbers we were seeing. It's a total game-changer for campaign integrity.”
Stuart Parkin
Director of Operations, Regit
“Tapper's blocking technology purifies our paid media traffic which roughly equates to a 36x return against its subscription costs. It's certainly one of the easiest-to-implement tools in our entire marketing stack.”
Reno Mindemann
Head of Growth, Kama Capital
“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 competitor clicks on Display & Programmatic open exchange.
On the open exchange, any DSP buyer can target the same publisher inventory and audience segments as you. Competitors can direct bot networks or click farm operations at your creative assets, generating fraudulent click signals that inflate your costs and exhaust your budget. Because the RTB auction completes in milliseconds with no human review, this interference is indistinguishable from genuine engagement without dedicated monitoring.
Your DSP optimises delivery based on click and conversion signals. When competitor interference inflates your click volume, the DSP interprets those clicks as real audience intent and adjusts bidding, targeting, and creative delivery accordingly. Your algorithm chases fraudulent engagement patterns instead of genuine buyer behaviour, raising CPMs and reducing the quality of real impressions your budget delivers.
Yes. Tapper operates at the impression and click level, identifying and removing competitor-origin invalid traffic across your existing open exchange buy. You do not need to restructure your buying strategy to get protection. That said, combining Tapper monitoring with selective PMP deals for your highest-value audience segments is an effective dual strategy.
