Click stuffing on affiliate CPI campaigns
Click stuffing on CPI campaigns floods your attribution model with invalid clicks, stealing install credit from legitimate publishers and channels that genuinely drove your app acquisitions.

Click stuffing on CPI programs corrupts install attribution and steals commission from legitimate publishers
Click stuffing on CPI affiliate programs works by injecting invalid tracking cookies or click events into the attribution path of users who will later install your app, regardless of whether they ever interacted with the stuffing publisher's content. When the user installs your app, the stuffed click appears last in the attribution chain and claims the CPI commission. Your legitimate affiliate publishers, who engaged the user through genuine content promotion and drove the real install intent, receive no credit and no commission.
The scale of click stuffing damage on CPI programs is often masked by healthy overall install volumes. Because installs are still occurring, the abuse is less visible than fake install generation. The harm shows up in publisher ranking data: your legitimate high-quality UA publishers appear to underperform because their genuine install attributions are systematically intercepted by the click stuffing operation. Your program's tier decisions and budget allocation increasingly reward the stuffing publisher at the expense of the genuine ones, degrading your UA program quality over time.
How Tapper stops click stuffing on Affiliate CPI campaigns
Three steps from connection to clean campaign data, no engineering required.
01
Connect your CPI affiliate tracking and MMP to Tapper
Tapper integrates with your affiliate network and mobile measurement partner, monitoring every click and install event with full attribution path analysis to detect click stuffing before it claims CPI commission.
02
Attribution path anomalies detected at every CPI install event
Tapper analyzes the relationship between each attributed click and the install event it claims credit for, flagging cases where the click path, timing, device signals, or session data indicate cookie stuffing rather than genuine publisher-driven install intent.
03
Legitimate CPI publishers protected, click stuffer commission rejected
Stuffed CPI install attributions are identified and rejected before commission calculation, restoring credit to the legitimate publishers who drove genuine app acquisition and preventing payouts to publishers operating cookie stuffing schemes on your CPI program.

Frequently asked questions
Click stuffing on CPI programs injects a tracking cookie or last-click attribution event from a stuffing publisher into the session of a user who will later install the app. The injection happens without the user's knowledge, typically through hidden iframes on unrelated web pages or malicious ad creatives. When the user installs the app through any channel, the stuffed click appears as the last touch before install and claims the CPI commission. The legitimate publisher who genuinely drove the install intent receives nothing.
Click flooding generates massive volumes of invalid clicks to contaminate the attribution model statistically, hoping some will appear as last-touch before real installs. Click stuffing is more surgical: it places specific injected cookies or attribution events on users whose install probability is already high, ensuring a much higher rate of hijacked last-touch attribution per invalid click. Click stuffing is more efficient per invalid event; click flooding operates at greater volume.
Tapper works most effectively when connected to both your affiliate tracking and your MMP, as the cross-reference between click data and install data enables precise attribution path analysis. However, Tapper can also identify click stuffing patterns from affiliate tracking data alone, through analysis of click timing relative to install events, session quality scoring, and publisher-level conversion pattern anomalies. Connecting the MMP data enhances detection accuracy for the most sophisticated stuffing operations.
