How to Read a Cookie Window
A 24-hour cookie on a researched product is worth zero. A 120-day cookie on an impulsive one is gold. Match the window to the buying journey.
A cookie window is how long, after someone clicks your link, you still get credit if they buy. It sounds like a detail. It's actually half of your effective commission rate.
The mistake is reading the window in isolation. What matters is the **match between the window and the buying journey**:
- **Impulse products** (plugins, apps, cheap tools): short windows are fine. People click and buy the same day. - **Researched products** (hosting, courses, VPNs): people comparison-shop for days or weeks. A 7-day window here quietly deletes your sales — they bought on someone else's click. - **High-ticket products** (Liquid Web, business services): journeys run weeks to months. Below a 60-day window, assume significant loss.
Quick example from the database: Amazon Associates — up to 10% commission, 24-hour cookie. On impulse buys, great. On researched electronics, brutal. Semrush — 40% recurring, 120-day cookie, on a product SEO readers research heavily. That window is doing as much work as the rate.
Before you commit to any program, write one sentence: 'My reader typically takes ___ days from interest to purchase.' If the cookie window is shorter than that sentence, the advertised rate is fiction.
