Stop click stuffing on mobile app campaigns
Click stuffing floods your tracking links with invalid clicks to claim attribution credit for organic installs, stealing CPI payouts from legitimate UA channels.

Click stuffing steals attribution credit from your best-performing UA channels
Click stuffing on mobile UA campaigns works by generating a high volume of invalid clicks against your tracking links in a short window. The goal is simple: ensure that when a real user installs your app organically or through a legitimate channel, an invalid click appears as the last touch before install and claims the CPI payout. The organic install was going to happen anyway. The bad actor has simply inserted itself into the attribution chain to extract payment for a conversion it played no role in driving.
The downstream effect of click stuffing is a systematic undervaluation of your organic and high-quality paid channels. As organic installs are misattributed to invalid sources, your true organic conversion rate appears lower than it is. Paid channels that actually drove installs receive less credit, and budget decisions are made on attribution data that fundamentally misrepresents where growth is coming from. UA managers scaling budgets based on this data will consistently overspend on sources heavy with invalid traffic and underinvest in genuine performers.
How Tapper stops click stuffing on Mobile
Three steps from connection to clean data, no engineering required.
01
Integrate Tapper with your MMP and tracking links
Tapper monitors all clicks flowing through your mobile tracking links, integrating with AppsFlyer, Adjust, Kochava, Singular, Branch, and your ad networks.

Click flood patterns detected before attribution fires
Velocity analysis identifies click stuffing attacks in progress. Invalid clicks are flagged before they can claim attribution credit for incoming installs, protecting the integrity of your CTIT window.
03
True channel performance restored in your MMP
With click stuffing excluded, organic installs are attributed correctly and your genuine paid channels receive accurate credit. Your MMP data reflects where installs are actually coming from.

Frequently asked questions
The terms are often used interchangeably. Technically, click stuffing refers to the injection of invalid clicks with the intent to claim attribution for genuine organic installs. Click flooding is the broader tactic of generating high click volumes to overwhelm the attribution window. Both are designed to insert an invalid source as the last touch before install, and both are detected by Tapper through velocity and pattern analysis.
Ad networks with less transparent publisher ecosystems and campaigns using third-party traffic sources are most exposed. In-app advertising placements, particularly on smaller networks, are commonly used as the medium through which stuffed clicks are injected. CPI campaigns are the primary target because each attributed install generates a direct payout.
Yes. Click stuffing targets your tracking links, which remain active regardless of campaign status. Invalid clicks can be fired against your links at any time in anticipation of organic installs. Tapper monitors all click traffic against your active tracking infrastructure, not just traffic from live campaigns.
