How Coupon Websites Work in 2026
Coupon websites help shoppers save money by aggregating discounts/ deals from retailers. They operate primarily through affiliate marketing, earning commissions on sales driven via their links.
Affiliate marketing in coupon space works on three levels
- Coupon Website ie. Publisher Level
- Affiliate Network ie. Network Level
- Brand ie. Advertiser Level
Coupon Websites ie. Publishers drive shoppers to their website using organic or paid traffic( Google ads, Meta Ads, TikTok Ads etc) where the shopper searches for deals by store, category, or product, then click a coupon or link that redirects to the retailer's site with the code pre-applied or ready to copy. During checkout, shoppers enter the code in a designated field, where the system validates it against rules like expiration dates or minimum spend.
Coupon sites partner directly with brands or affiliate networks like Rakuten, CJ Affiliate, Awin, Impact.com to obtain promo codes and deals. Some generate exclusive codes directly with merchants, while others aggregate public offers or accept user submissions after verification. Popular examples includeRetailMeNot, Coupons.com, and Slickdeals, which list deals from thousands of retailers.

These Affiliate networks partner with brands on one side and publishers on the other.Specific tracking links are provided by networks to publishers which attached to the coupon link. So when a shopper clicks on the coupon link a the tracking link attached to it is used to validate which coupon website has arrived from to the brands website.
