(And How It’s Costing You Real Leads)
In the performance marketing ecosystem, there's a long-standing obsession with building “perfect funnels.” Every click tracked, every touchpoint mapped. But as Nabeel Shariff recently pointed out, the industry may be “over-indexing on the funnel and under-indexing on the data that fills it.”
This idea cuts deep. And it should, because the quality of your funnel is only as good as the quality of traffic entering it.
Funnels Don’t Fail, Data Does
Funnel optimization assumes a clean slate: that your MQLs are valid, your CPLs are real, and your attribution is accurate. But what if none of that is true?
- A recent study showed that over 75% of leads in paid campaigns are fake or unqualified.
- Bots and bad affiliates are actively gaming performance marketing platforms, especially in industries like financial services, real estate, and insurance.
- These leads inflate CPLs, distort ROAS, and contaminate your CRM with junk.
So while you're busy nurturing your funnel, your foundation is already crumbling.
What Is Lead Generation Fraud, and Why Should You Care?
Lead generation fraud is the creation of fake leads using bots, click farms, or deceptive affiliate practices. It often looks like:
- Form fills from invalid or stolen data
- Out-of-geo traffic with no intent to convert
- Spam sign-ups that pollute your pipeline
- Misleading referral links from affiliate fraud
This isn’t just a “fraud team” problem. It’s a revenue operations problem. A brand trust problem. A growth ceiling.
And if you're not actively filtering it out, your entire performance stack, from your CRM to your reporting, is skewed.
Performance Marketing Needs Performance Validation
If your growth strategy relies on volume without validation, you're not scaling, you're bleeding.
That’s why forward-thinking CMOs are shifting focus from funnels to filtering. Because traffic quality is no longer a nice-to-have, it's your first line of defence.
