Bot traffic fraud on mobile app retargeting campaigns
Bots clicking your retargeting ads waste your re-engagement budget and generate fake re-engagement events that corrupt your retargeting performance data. Tapper detects bot traffic on mobile retargeting campaigns and keeps your re-engagement attribution clean.

Bots simulate re-engagement clicks and fake re-engagement events on retargeting campaigns
Bot traffic on mobile retargeting campaigns attacks at two levels. Click-level bots generate fraudulent clicks on your re-engagement ads, consuming retargeting budget that should reach real lapsed users and creating false click volume in your attribution data. Event-level bots go further, simulating the re-engagement events your retargeting campaign optimises on, such as app opens, session initiations, or re-engagement actions, generating CPA payouts for re-engagement that never involved a real lapsed user.
The data corruption from bot-generated re-engagement events is particularly damaging because retargeting campaign optimisation relies on accurately measuring which lapsed user segments respond to re-engagement and which in-app actions they complete after returning. When bot traffic pollutes this data, your retargeting algorithm optimises toward audience segments based on false re-engagement signals, and your segment-level re-engagement rate benchmarks become unreliable for making creative and audience decisions. Tapper's session behaviour analysis identifies bot-generated click and event activity that lacks the genuine user patterns of real lapsed users returning to your app.
How Tapper stops bot traffic on Mobile retargeting
Three steps from connection to clean campaign data, no engineering required.
01
Connect your MMP and retargeting networks
Tapper integrates with your mobile measurement partner and retargeting networks, monitoring re-engagement clicks and post-click events for bot activity signals.
02
Bot clicks and fake re-engagement events detected
Tapper applies behavioural analysis, device fingerprinting, and session pattern review to identify bot-generated clicks and simulated re-engagement events before they reach your MMP attribution.
03
Clean re-engagement data and protected retargeting budget
Bot activity is excluded from your retargeting attribution. Your re-engagement rates reflect genuine lapsed user behaviour and your retargeting budget reaches real users who can generate actual revenue.

“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 bot traffic on Mobile App retargeting.
Bots targeting retargeting campaigns click on re-engagement ads served through ad networks without any genuine user intent to return to the app. More sophisticated bot operations then simulate the re-engagement events that trigger CPA payouts, such as app open events or re-engagement action completions, by firing MMP SDK calls that appear structurally valid but lack genuine user session context.
Yes. If bot re-engagement events populate your MMP retargeting analytics, the algorithm learns incorrect patterns about which user segments respond to re-engagement. Over time, your retargeting audience strategy is optimised based on bot response patterns rather than genuine lapsed user behaviour, reducing the efficiency of your re-engagement campaigns for real users.
Yes. Sophisticated bots can generate valid SDK event calls, but they cannot replicate the full complexity of genuine user session behaviour: natural navigation patterns, realistic timing between actions, interaction variation, and the contextual engagement sequences that real returning users produce. Tapper analyses this full session context to identify bot activity that passes event-signal verification.
