Fraud Detection For E-Commerce Brands

Best practices for detecting and preventing fraud in e-commerce campaigns using Everflow's native tools.

Overview

If you run an e-commerce brand on Everflow, your fraud risks look different from mobile app campaigns or lead generation. The most common issues — coupon poaching, proxy-masked traffic, and low-quality sources — require a specific set of tools and a measured approach.

This guide walks through the native Everflow features that matter most for e-commerce fraud detection. You don't need third-party tools to get started — everything below is built into the platform.

For general fraud prevention covering mobile and network traffic, see our Fraud Prevention & Detection guide.

Know Your Baseline: Click to Conversion Time

The Click to Conversion Time report is your first line of defense. It shows how long it takes for a click to become a purchase — and once you know your normal range, outliers become obvious.

What to Look For

In e-commerce, most legitimate purchases happen within a predictable window. If your average customer takes 10–30 minutes to browse and buy, that's your baseline.

Watch for two red flags:

  • Conversions under 5 seconds: Likely coupon poaching — a partner injects their tracking click right before checkout to claim credit for a sale they didn't drive.
  • Conversions after 24+ hours: May indicate click stuffing — a partner fires clicks in the background, hoping one eventually matches a natural purchase.

Access the Report & Set Rejection Rules

Navigate to Reporting → Click To Conversion Time Set your date range and select Seconds or Minutes as the time unit Filter by specific Offers to focus on your e-commerce campaigns Look for spikes at the extremes — review the distribution for patterns outside your expected range
Take It Further: Automatic Rejection Rules

Once you've established your baseline, you can automatically reject conversions that fall outside your expected window. Go to Offers → Tracking & Controls and configure the Click to Conversion Time minimum and maximum thresholds.

Conversions outside this range will be rejected automatically — protecting your payouts without manual review.

Event Tracking & The Funnel Report

Conversion counts alone don't tell you whether traffic is real. What matters is engagement depth — are users adding items to cart, starting checkout, and completing purchases at reasonable rates? Or are conversions appearing with no upstream activity?

By tracking events at each stage of the buying journey, you can use the Funnel Report to compare traffic quality across partners down to the source level.

Recommended Events for E-Commerce

Recommended E-Commerce Event Funnel
1

Add to Cart

Tracks product interest. Healthy sources show add-to-cart rates proportional to clicks.

2

Checkout Started

Signals purchase intent. High add-to-cart but zero checkouts may indicate bot traffic.

3

Purchase

Your primary conversion event. Already tracked by default.

4

Upsell / Cross-Sell

Measures post-purchase engagement. Quality traffic converts on upsells at consistent rates.

Access the Funnel Report at Reporting → Funnel Select your events in order (Add to Cart → Checkout → Purchase → Upsell) Break down by Partner to compare traffic quality across sources Look for sources where users skip stages — conversions with no add-to-cart or checkout events are a red flag
Pro-Tip: Talk to your Customer Success team about which additional events make sense for your store. Beyond the basics, events like email signup, account creation, or wishlist adds can give you even deeper insight into traffic quality.

Proxy Traffic: The Pass-Through Approach

Proxy traffic — where a user's IP is spoofed to fake a location — is common in affiliate marketing. But blocking it immediately is a mistake. Many legitimate customers use VPNs, corporate networks, or privacy tools that look like proxies.

Instead of blocking outright, use Everflow's pass-through approach to investigate first:

1 Check Your Click Report First

Before changing any settings, check how much proxy traffic you actually have. Go to Reporting → Clicks and add the Proxy column to your report.

If proxy clicks are a tiny fraction of total traffic, you may not have a problem worth solving yet.

2 Enable Pass-Through (Don't Block Yet)

If you see significant proxy traffic, resist the urge to block immediately. Go to Offers → Targeting and set the Proxy Traffic setting to Fail Traffic (pass-through mode).

This allows proxy clicks to proceed to your landing page and convert, but marks them as failed — protecting you from paying partners for potentially fraudulent traffic while still collecting data.

3 Review the Results

After running in pass-through mode for a week or two, review the data. Check whether proxy-flagged conversions have normal engagement patterns (add to cart, checkout, purchase) or look suspicious.

Some will be legitimate customers using VPNs or corporate networks. Others may be clearly fraudulent.

4 Block If Confirmed

Once you have enough data to confirm proxy traffic from specific sources is fraudulent, switch from Fail Traffic to Block in the Offer Targeting settings.

You can also address it at the partner level — talk to the partner about their traffic sources before cutting them off entirely.

Alerts That Matter for E-Commerce

Everflow's alert system notifies you when traffic patterns deviate from normal. Rather than monitoring everything, focus on the alerts that catch the most common e-commerce fraud signals.

Set up alerts at Communication Hub → Alerts

Recommended Alerts for E-Commerce

Conversion Rate (CVR) Spike Critical

Alert when CVR exceeds your normal range. An unusually high conversion rate from a single partner often indicates fraud rather than great performance.

Click to Conversion Time High

Alert on conversions happening faster than your established baseline. Catches coupon poaching in real time.

Invalid Click Rate Medium

Monitor the ratio of invalid to total clicks. A sudden increase may indicate bot activity or click stuffing.

Total Conversions Spike Standard

Alert on sudden volume increases from individual partners. Legitimate traffic growth is usually gradual.

Event Rate (EVR) Drop Monitor

If a partner's event rate drops significantly (purchases with no add-to-cart events), traffic quality may have changed.

Note

Refund rates aren't available as an automated alert. Make it a weekly habit to check Reporting → Refunds manually and compare patterns across partners.

Monitor Your Refunds

High refund rates tied to specific partners or sources can signal fraud — especially if refunds spike after a promotional push. Make it a habit to check the Refunds Report weekly and compare refund patterns across your top partners.

If one partner consistently drives orders that get refunded at a higher rate, investigate their traffic sources before adjusting payouts.

Third-Party Fraud Scoring

For additional protection, Everflow integrates with fraud scoring platforms that evaluate IP addresses, device data, email addresses, and billing details in real time.

These integrations are optional but valuable for high-volume campaigns. See our integration comparison guide for help choosing the right fit.
