Static coupon code vs auto-applied link — the auto link is quietly stealing your credit

Static coupon code vs auto-applied link — the auto link is quietly stealing your credit

When a brand offers both a code AND a 'discount auto-applies at this link,' read the fine print.

— Static code (you type WELCOME15): tracks via the code, survives even if the cookie dies. Bulletproof attribution.

— Auto-apply link: smoother UX, higher conversion, BUT if the cookie gets stripped (in-app browsers, privacy modes) you lose the sale credit AND the customer still got the discount.

I had a month where 'phantom redemptions' on an auto-link ate ~15% of expected commission. Switched my high-traffic placements to the typed code.

Use auto-apply for clean desktop traffic, static codes for mobile/in-app. Audit where your traffic actually comes from first.
