Display and programmatic ad fraud protection for retail
Retail display campaigns on the open exchange face bot traffic inflating impression counts, domain spoofing consuming shopping audience CPMs, and invalid clicks corrupting the conversion data your DSP uses to optimise ROAS.

Programmatic fraud drains retail display budgets and corrupts ROAS data at scale
Retail advertisers deploying programmatic display across prospecting, retargeting, and seasonal peak campaigns face bot traffic at every inventory tier. On the open exchange, where retail brands compete for shopping audience CPMs during key trading periods, fraudulent publishers spoof premium retail and lifestyle domains to capture bids at premium rates while serving impressions to non-human traffic. Invalid traffic rates on open exchange inventory average 20-40%, meaning that during high-spend periods such as end-of-year sales, a significant portion of every display budget reaches no real shopper.
Retargeting campaigns face a specific fraud vector. When bot traffic or invalid users visit your e-commerce site and trigger retargeting pixels, they are added to your retargeting audiences. Your DSP then serves display ads to these invalid users, paying retargeting CPMs for impressions that will never convert. Meanwhile, the engagement signals generated by retargeted bot traffic feed back into your campaign's learning data, teaching your DSP that these invalid audience profiles are worth retargeting and distorting the audience models that underpin your ROAS targets.
Tapper analyses traffic at the device and behavioural level across your full programmatic buy, filtering bot impressions, domain-spoofed inventory, and invalid retargeting signals before they inflate your metrics or corrupt your campaign data. With clean impression and click data, your DSP optimises toward real shoppers, your retargeting audiences contain genuine site visitors, and your ROAS measurements reflect actual campaign performance.

Behavioural analysis, device fingerprinting, and domain verification identify bot impressions, fraudulent publishers, and the invalid audience signals that corrupt retargeting campaign performance.

“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 you need to know about protecting retail ad spend on Display & Programmatic.
Bot traffic harms retail programmatic campaigns at two levels. First, it consumes impression budget, paying CPMs for placements that no real shopper sees. Second, bot interactions with display ads and landing pages generate fake engagement signals that feed into your DSP's audience model, teaching the algorithm that bot-like behaviour represents your target shopper. Your prospecting campaigns drift toward invalid traffic profiles and retargeting audiences become contaminated with bot-generated pixel fires.
Yes. During high-spend periods such as end-of-year sales, summer promotions, and back-to-school seasons, retail advertisers significantly increase programmatic display budgets. Fraud operations are aware of these spending patterns and increase activity accordingly, targeting the higher CPMs that retail brands pay during peak periods. Tapper provides continuous monitoring with no volume limits, so protection is consistent regardless of budget level.
Dynamic product ads use site visit and product view data to serve personalised display ads to previous visitors. If bot traffic inflates your site visit data, your dynamic product campaigns will retarget invalid users with product ads, wasting retargeting CPMs. Tapper filters invalid site visits at the traffic level, ensuring your dynamic product ad audiences contain only genuine shoppers who have actually engaged with your products.
Yes. With invalid traffic filtered from your campaign data, your conversion attribution accurately reflects which inventory sources, publishers, and audience segments are driving genuine purchases. This clean data allows your media team to shift budget toward high-quality inventory and suppress sources that deliver impressions without real shopping conversions.
Tapper specialises in protecting standard programmatic display buying on the open exchange and private marketplace. For retail media network inventory bought through external DSPs, Tapper's monitoring applies to the click and impression data available through your DSP integration. Inventory bought directly through a retailer's own media platform sits outside the standard programmatic stack and would require a separate integration assessment.
