Fingerprint Tracking
Fingerprint tracking identifies users by collecting device, browser, and system attributes to create a unique profile, enabling attribution without relying on cookies.
What it means in practice
Fingerprint tracking is a cookieless identification method that builds a unique profile from a combination of device and browser attributes — screen resolution, installed fonts, time zone, browser version, operating system, GPU renderer, and other signals. When combined, these attributes create a digital fingerprint that can identify a user across sessions without requiring cookie duration or stored identifiers.
In affiliate marketing, fingerprint tracking serves as a fallback or complement to primary attribution methods like S2S tracking and pixel tracking. As browsers increasingly block third-party cookies and users employ ad blockers, cookieless attribution methods become more relevant. Fingerprinting fills gaps where traditional tracking tokens fail — such as when a user clears cookies between clicking an affiliate link and completing a conversion.
The accuracy of fingerprint tracking depends on the number and stability of signals collected. High-entropy signals like GPU renderer or canvas hash provide strong uniqueness, while low-entropy signals like screen resolution are common across many devices. A well-implemented fingerprint can achieve 90%+ accuracy for returning visitor identification, though it is generally less precise than server-side click ID matching.
Privacy regulations including GDPR and ePrivacy treat fingerprinting as a tracking technology that may require user consent, similar to cookies. Operators using fingerprint-based attribution must ensure their implementation complies with applicable data protection rules in each jurisdiction they operate in.

How Track360 handles this
Track360 supports multiple attribution methods including server-side tracking, postbacks, and cookieless fallbacks. Operators can configure attribution logic that combines primary S2S tracking with supplementary identification methods to maintain conversion accuracy across different tracking scenarios.

S2S Tracking (Server-to-Server)
S2S tracking records affiliate conversions server-to-server, bypassing the browser. Unaffected by ad blockers or cookie restrictions.
Pixel Tracking
Pixel tracking uses a small image tag or JavaScript snippet embedded on a conversion page to notify the tracking platform when a user completes a qualifying action. The pixel fires in the user's browser, sending conversion data back to the tracking server for affiliate attribution.
Cookie Duration
Cookie duration is the length of time a browser cookie remains active after a user clicks an affiliate link. If the user converts within this window, the affiliate receives credit for the referral. Typical durations range from 30 to 90 days depending on the vertical and program.
Click ID
A click ID is a unique identifier generated for each click on an affiliate tracking link, serving as the key that connects an initial click event to downstream conversions for attribution purposes.
Cross-Device Tracking
Cross-device tracking is the process of identifying and connecting a single user's activity across multiple devices -- such as mobile, desktop, and tablet -- so that conversions can be attributed accurately regardless of where the final action occurs. It addresses the gap that arises when a user clicks an affiliate link on one device but converts on another.
Tracking Token
A tracking token is a parameter appended to an affiliate URL that carries attribution data -- such as affiliate ID, campaign, and creative -- through the conversion journey for accurate attribution.
Duplicate Account Detection
Duplicate account detection is the process of identifying when a single person creates multiple accounts to exploit affiliate program incentives such as signup bonuses or CPA offers.
Attribution Window
The defined time period after a user clicks an affiliate link during which any qualifying conversion is credited to the referring affiliate.
