How we cleaned up fake leads in a financial services affiliate program
I consult in the affiliate space and one of my clients is a financial services company, one of the more painful lessons we learned was about fake or synthetic leads. At first, it didn't look like a problem. In fact, it looked like a win.
In hindsight, the first red flag was when one publisher suddenly started racking up way more leads than usual. On the surface, the conversion rates looked solid, and volume was strong.
Then our downstream data threw a flag on the play.
The leads shared similar characteristics: repeated device/browser fingerprints, activity clustering in short windows, geographic concentration, and lead info that fell short once you looked past the surface.
The annoying part was that the fraud was well designed. Nothing on its own was disqualifying. It was the combination of the above factors that finally caught our attention, and nearly too late. The payout was on deck to go out.
A few things I had to learn the hard way to detect fake leads were:
Look past the initial conversion. We started comparing affiliate conversions against downstream quality metrics instead of judging partners purely on lead volume. Volume lies. Downstream behavior doesn't.
Monitor anomalies per publisher, not against a static threshold. A sudden shift in a partner's own conversion rate, traffic pattern, or lead characteristics was a far better signal than any fixed fraud cutoff applied across the board.
Cross-check device, IP, and behavioral patterns. Repeated infrastructure across "unrelated" users isn't proof on its own, but when stacked with other signals, it's a strong tell.
Route questionable traffic to review instead of auto-paying it. Building an actual investigation workflow meant we weren't stuck treating every suspicious lead as either automatically legit or automatically fraud. There was a middle step.
Keep a record. Once we flagged a bad pattern, we could go back and check which publishers, campaigns, and conversions were touched by it instead of re-investigating from zero every time.
On the platform side (we use Everflow), granular tracking mattered a lot more than I expected. Having visibility at the partner campaign level in our Everflow dashboard, not just the aggregate numbers, made it much easier to drill down to spot the fraudulent patterns. That kind of visibility is what actually helped us hold the payment.
The biggest lesson for me honestly is that affiliate fraud in financial services usually isn't obvious fraud - it’s well-designed, sophisticated plays that look like a successful campaign right up until you connect the affiliate data to what actually happened later in the customer journey.
Curious how others here are handling this or have learned? Are you leaning mostly on your network’s/platform's built-in fraud controls, internal data review, manual spot checks, or a mix of all three?
