What changed
Safari, Firefox and increasingly Chrome block third-party cookies — the mechanism old affiliate networks used to remember which affiliate sent a visitor across sites. Tracking that depended on them undercounts, and affiliates are underpaid without knowing it.
Counting at the link
A tracked link records the open on the link's own domain before sending the person on: the app it came from, the city, the device, second visits. No third-party cookie is involved. That is the standard level on Shopmycode, on any page.
Reporting the result
When the visitor lands on the brand's own page, one line on the thank-you page tells the platform a sign-up or order happened, and it is matched to the link that brought the visitor. When the result happens in the brand's system, one call reports it. Marketplaces report through their own programs. None of this needs a cookie on a third-party site.
Promo codes
A code attributes the person who typed it at checkout, days later, in another browser. Give each marketer a code beside the link; both are shown on one line.
What stays invisible
A tap inside another native app, a purchase on a site that does not report, an order on a marketplace before it reports. A platform should say so rather than guess; Shopmycode labels results as live or waiting and shows what it cannot see.
