CASE FILE: One exclusive code, +210% page conversion
A mid-tier electronics coupon site swapped a stale 'up to 40% off' generic banner for a single merchant-supplied exclusive code on its top landing page. Confirmed metric from the operator: conversion on that page jumped from 1.9% to 5.9% over a 30-day window, while traffic held flat. Revenue per session nearly tripled because the exclusive killed the 'is this even valid?' hesitation that tanks generic-code pages.
Why it matters: one verified exclusive beats ten scraped generics. The lift came from trust, not volume.
We hear the merchant granted it after the site agreed to a 14-day uptime guarantee. Worth modeling on your worst-converting page.
