Lower your CPI by eliminating invalid traffic before it becomes installs.
Tapper uses pre-bid exclusion, in-stream invalid click prevention, and attribution verification to stop invalid traffic at every stage of your mobile acquisition funnel, before it wastes budget or corrupts your bidding signals.
Why CPI keeps increasing in mobile acquisition
Each invalid signal that enters your data layer makes your bidding algorithms less accurate. Over time, CPI rises, ROAS falls, and campaign performance degrades, without any obvious cause.
Invalid clicks waste budget before an install is even attempted
Click injection and SDK spoofing steal attribution from real sources
Fake installs corrupt bidding signals and raise target CPI over time
Invalid post-install events train algorithms toward invalid user profiles
Your MMP cannot independently validate the data it receives
How Tapper protects mobile user acquisition
Four layers of protection that cover every stage where invalid traffic can enter your funnel and inflate your CPI.
Pre-bid exclusion
Block known bad actors before your ad is even served. Tapper maintains continuously updated exclusion lists of invalid IPs, devices, and audience segments, stopping wasted spend before it starts.
In-stream invalid click prevention
Every click is scored in real time against behavioral signals and invalid traffic patterns. Bots, click farms, and suspicious traffic are blocked before they reach your MMP.
Attribution verification
Tapper sits alongside your MMP as an independent layer to validate every install. Click injection, SDK spoofing, and misattribution are detected and removed before they corrupt your campaign data.
Post-install analysis
Invalid traffic does not stop at the install. Tapper monitors in-app behavior for fake engagements, bulk invalid events, and anomalous activity patterns that indicate invalid users slipping through post-attribution.
Every type of invalid mobile traffic. Covered.
Tapper detects and blocks the full range of invalid traffic vectors in mobile acquisition, not just invalid clicks.
Fake installs
Bot-generated or incentivized installs that never come from real users, wasting budget and inflating CPI.
Click injection
Malicious apps that fire invalid clicks at install time to hijack attribution from legitimate sources.
SDK spoofing
Simulated install events generated without any real device or user, invisible to standard MMP checks.
Attribution abuse
Manipulated attribution signals that credit invalid sources with real conversions you legitimately earned.
Fake in-app events
Bulk invalid post-install events that distort your optimization signals and corrupt bidding algorithms.
Incentivized traffic abuse
Low-quality users incentivized to install with no intent to engage, driving up installs while destroying LTV.

What Tapper delivers
Lower CPI
Remove invalid installs from your data and your bidding algorithms start optimizing toward real users, driving CPI down over time.
Cleaner attribution data
Independent install validation alongside your MMP gives you a verified view of what is actually driving performance.
Better bidding signals
When your campaign data reflects only real users, automated bidding learns from real users, not invalid installs.
Confident scaling
Expand to third-party networks and new channels without amplifying invalid traffic exposure or increasing blended CPI.
Full funnel visibility
See exactly where invalid traffic is entering your funnel, by network, publisher, or creative, and act on it with real data.

“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
40%
higher conversion rate
“When we take low-quality traffic out of the funnel before it reaches the algorithm, the campaign optimizes 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.”

Frequently asked questions
Invalid installs inflate CPI in two ways: they waste budget directly, and they corrupt your bidding algorithms so campaigns optimize toward invalid user profiles. Tapper removes invalid traffic before it enters your data layer, so your budget works only on real users and your CPI reflects genuine acquisition costs.
No. Your MMP is built to track and credit installs, not to validate them. It cannot independently detect click injection, SDK spoofing, or attribution abuse. Tapper sits alongside your MMP as an independent verification layer, catching invalid traffic that your attribution stack cannot see on its own.
Pre-bid exclusion means that before your ad is even shown, Tapper checks the incoming impression against a continuously updated list of known invalid IPs, devices, and audience segments. If a match is found, the bid is suppressed and your ad is never served to that traffic, eliminating waste before it starts.
Yes. Invalid traffic rates are significantly higher on third-party mobile ad networks. Tapper gives you the protection layer to expand confidently to new networks without amplifying invalid traffic exposure, reducing your blended CPI while maintaining install quality.
Setup typically takes around 10 minutes. Tapper works with the major MMPs, and protection then runs on its own across your campaigns.
