If you’ve ever watched a user leave your site to search for a coupon code, you already understand the problem.

They may come back.
They may not.

And if they don’t—your attribution is gone.

For affiliate publishers, coupon data quality directly impacts conversions, user trust, and revenue. When coupon codes don’t work or feel unreliable, users look elsewhere—and that’s where leakage begins.

That’s exactly what FMTC’s CEO, Brook Schaaf, discussed with Dustin Howes on the Affiliate Nerd Out podcast.

The Problem: Coupon Leakage and Data Quality Issues

Many publishers rely on coupon content to drive conversions—but outdated or inaccurate codes create friction in the user experience.

When users don’t trust the offers on your page, they leave to find one that works. That opens the door for:

  • Lost commissions
  • Broken attribution
  • Reduced user trust

Even a single bad experience can train users to skip your site entirely next time.

The difference between losing a user and converting them often comes down to one thing: data quality.

That’s why more publishers are turning to FMTC’s verified coupon data instead of relying on scraping or manual updates.
