Definition
A tracker is the unique tracking link, code, or pixel-based identifier assigned to each affiliate by an operator's affiliate platform, used to attribute referred visitors, registrations, deposits, and subsequent player activity back to the correct affiliate account. It is the foundational technical infrastructure underpinning the entire iGaming affiliate commission system, since without accurate tracking, no CPA, RevShare, or Hybrid payment could be reliably calculated or attributed.
Technically, a tracker typically works through a combination of URL parameters (such as a unique affiliate ID appended to the operator's domain, e.g., casino.com/?ref=AFF123) and browser cookies that persist the affiliate attribution for a defined cookie lifetime, often 30 to 90 days. When a visitor clicks the tracker link, the operator's system logs the click, sets a tracking cookie in the visitor's browser, and if that visitor later registers and deposits within the cookie's validity window, the entire chain of activity - registration, FTD, subsequent NGR - is attributed to the originating affiliate's account in the platform's reporting dashboard.
Most affiliate programs run on established affiliate tracking software platforms (such as Income Access, MyAffiliates, or in-house systems), which provide affiliates with real-time or near-real-time dashboards showing clicks, registrations, FTDs, and revenue generated per tracker. Sophisticated affiliates often create multiple distinct trackers for different traffic sources, landing pages, or campaigns (a practice called sub-ID tracking or "sub-tracking"), allowing them to compare conversion performance across channels and optimize spend accordingly.
Trackers are essential in iGaming because attribution accuracy directly determines whether affiliates get paid correctly for the traffic and players they generate - any technical failure, ad-blocker interference, cookie deletion, or cross-device tracking gap can result in lost commissions for legitimate referrals. This has driven increased industry adoption of more resilient tracking methods, including server-to-server (S2S) postback tracking, which doesn't rely on client-side cookies and is far less vulnerable to browser privacy restrictions or ad blockers.
A frequent and costly mistake among affiliates is relying solely on cookie-based tracking without verifying it against S2S postback data, leading to under-reported conversions especially from mobile traffic or privacy-focused browsers that block third-party cookies. Affiliates should regularly test their tracker links across devices, confirm operators support S2S tracking as a backup, and audit reported numbers against their own analytics.
Worked example
Your tracker link: casino.com/?ref=AFF123. Every player who clicks and deposits is attributed to your account.
