Bot traffic fraud on in-app event campaigns
Bots generating fake clicks and simulated in-app events corrupt your CPA data and drain your post-install event budget. Tapper detects bot traffic targeting in-app event campaigns and removes it before it reaches your MMP or your network algorithms.

Bots simulating in-app events corrupt your CPA model from the inside
Bot traffic targeting in-app event campaigns operates at a more sophisticated level than simple click fraud. Advanced bot operations simulate not just the click that initiates attribution, but the post-install user journey itself: firing fake tutorial completion events, simulated in-app purchase signals, and manufactured level completions to trigger CPA payouts that require evidence of genuine post-install engagement. Your MMP records these events as valid, your network counts them toward your CPA targets, and no real user ever interacted with your app.
The damage to your event data is compounding. As bot-generated events populate your in-app analytics, your benchmark engagement metrics become inflated: your average tutorial completion rate appears higher, your purchase conversion rate looks better than reality, and your level completion timelines skew toward the instant completions that bots produce. Any optimisation decision based on these metrics, whether bid adjustments, creative testing, or audience targeting, is built on false data. Tapper analyses the full session lifecycle that produces each in-app event, looking for the natural variation, timing patterns, and interaction sequences that genuine users produce and bots cannot replicate.
How Tapper stops bot traffic on Mobile in-app events
Three steps from connection to clean campaign data, no engineering required.
01
Connect your MMP and ad network stack
Tapper integrates with your mobile measurement partner and ad networks, monitoring both click data and in-app event streams for bot activity signals across your full campaign stack.
02
Bot-generated event signatures detected through session analysis
Tapper analyses the session behaviour leading to each in-app event, identifying the absence of genuine user interaction patterns, unrealistic timing, and the repetitive signatures characteristic of bot-generated event sequences.
03
Clean event data and protected CPA targets
Bot-generated events are excluded from your MMP attribution and your network reporting. Your CPA targets reflect genuine user acquisition costs and your event benchmarks are based on real user behaviour.

“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 in-app events.
Sophisticated bot operations can simulate the MMP SDK signals for post-install events, firing tutorial completion, purchase, or level completion event calls that appear structurally valid to your MMP. What they cannot replicate is the full behavioural session that precedes a genuine event: the natural navigation patterns, realistic timing between actions, and variation in interaction that real users produce. Tapper analyses this full session context, not just the event signal itself.
Warning signs include unusually high event completion rates compared to organic benchmarks, event timing that clusters around suspiciously fast completion windows, event volume spikes that do not correspond to any campaign changes, and in-app event cohorts that show zero downstream engagement or revenue after the tracked event. Tapper provides event-level fraud analysis that surfaces these patterns across your full MMP data.
Yes. Tapper's analysis applies to every in-app event type in your MMP, not just the primary CPA event your campaign optimises on. Purchase events, subscription initiations, and other high-value actions receive the same session-level behaviour analysis as tutorial completions and early engagement events, giving you confidence in the quality of your entire post-install funnel.
