Consider a fast-growing ecommerce brand with strong organic traffic and a well-run affiliate program. Revenue looks solid every month, but one odd trend appears: a mid-tier affiliate suddenly becomes the highest contributor, while trusted, high-quality partners stay flat.
At first, it feels like a performance win.
However, a closer look reveals the truth.
Most of those “affiliate-driven” traffic was from users who were already interested to buy from the brand. At the last moment, the credit shifts to the affiliate — even though they didn’t bring in a new customer. To burst this bubble, focus on what really adds value.

Signs to Identify Affiliate Fraud in Programs
Brands running affiliate marketing programs can spot key warning signs triggered by fraudulent activity, understand the mechanisms behind them, and uncover what these indicators truly reveal –
Unusually high clicks with low engagement or conversions
- What it is: Campaigns receive a high number of clicks but very few real actions like sign-ups, purchases, or engagement.
- How it happens: This is usually caused by click spamming, bot traffic, or forced redirects that create fake or unintentional clicks.
- What it indicates: Artificial traffic inflation aimed at organic hijacking, manipulating attribution and making performance appear better than it actually is.
Inflated installs with distorted click-to-install ratios
- What it is: High install volumes paired with unusually short click-to-install times or irregular conversion paths.
- How it happens: Driven by click injection techniques that hijack organic or paid traffic at the last moment.
- What it indicates: Attribution manipulation and conversion theft from legitimate marketing channels.
Abnormal growth from a small group of affiliates
- What it is: A few affiliates show sudden, disproportionate growth while overall program performance remains flat.
- How it happens: Often due to last-click hijacking of organic and paid installs
- What it indicates: Skewed performance reporting and possible conversion stealing rather than incremental growth.
Sudden spikes in installs from limited device models, OS versions, or IP ranges
- What it is: High volumes of activity originating from a narrow set of technical identifiers.
- How it happens: Generated using device farms, emulators, or automated traffic systems.
- What it indicates: Non-human traffic rather than genuine user acquisition.
Installs originating from unauthorized or unverified sources
- What it is: App installs coming from unofficial app stores, third-party APKs, or unknown publishers.
- Why it happens: APK tampering or manipulated distribution channels.
- What it indicates: High risk of fraud, poor user quality, security vulnerabilities, and low lifetime value.
Sharp spikes followed by rapid drops in activity and retention
- What it is: Sudden bursts in installs or sign-ups that collapse shortly after.
- Why it happens: Incent-based campaigns that attract reward-seeking, low-intent users.
- What it indicates: Artificial scale that fails to generate long-term engagement, retention, or revenue.
High volume of users completing only minimal actions
- What it is: Users perform just enough actions to trigger payouts and then disengage.
- Why it happens: Incent fraud, forced actions, or scripted behavioral flows.
- What it indicates: Low-quality acquisition that inflates metrics but delivers no sustainable business impact.
Traffic spikes during odd hours or irrelevant geographies
- What it is: Large traffic volumes (including clicks and impressions) coming in at unnatural times or from low-relevance regions.
- Why it happens: Bot networks, proxy servers, or geo-masking fraud operations.
- What it indicates: Automated or manipulated traffic designed to bypass detection.
High uninstalls or drop-off rates within the first 24–48 hours
- What it is: Users churn almost immediately after installation or signup.
- Why it happens: Forced installs, incentive-driven behavior, or misleading creatives.
- What it indicates: Poor user intent, weak onboarding quality, and wasted acquisition spend.
Unusually High Retargeting Conversions
- What it is: A sudden or consistent surge in conversions attributed to retargeting campaigns.
- Why it happens: Fraudulent sources manipulate attribution using techniques like click spamming, cookie stuffing, or last-click hijacking.
- What it indicates: Conversion hijacking rather than genuine retargeting impact.
