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.
What it means in practice
A tracking pixel is a 1x1 transparent image tag or a JavaScript snippet placed on a conversion page -- such as a registration confirmation or purchase thank-you page. When a user loads that page, the pixel fires an HTTP request to the tracking platform's server, passing along conversion details and any associated affiliate link identifiers. This allows the platform to attribute the conversion to the affiliate who drove the traffic.
The pixel-based attribution flow works as follows: a user clicks an affiliate link, and a cookie is set in the user's browser containing the affiliate's tracking ID and click timestamp. When the user later completes a conversion action and lands on the confirmation page, the embedded pixel reads the cookie data and sends it to the tracking server. The tracking platform then matches the conversion to the original click within the attribution window and credits the affiliate.
While pixel tracking was the standard attribution method for years, it has significant limitations in today's environment. Ad blockers can prevent pixels from loading entirely. Browser privacy features increasingly block or delete third-party cookies, breaking the link between click and conversion. JavaScript errors or slow page loads can prevent pixels from firing. For server-side events -- like trade executions or deposit confirmations that happen outside the browser -- pixels cannot capture the conversion at all. For these reasons, many affiliate programs now use S2S tracking as their primary attribution method and reserve pixel tracking as a secondary or fallback option.

Frequently Asked Questions
Common questions about pixel tracking, how it works in affiliate programs, and where it shows up across Track360's supported verticals.
A tracking pixel is a small image tag or JavaScript snippet placed on a conversion page. When a user loads the page after completing a qualifying action -- such as a registration or purchase -- the pixel fires a request to the tracking platform, passing conversion data that allows the platform to attribute the action to the affiliate who referred the user.

S2S Tracking (Server-to-Server)
S2S tracking is a server-to-server method for recording affiliate conversions where the advertiser's server communicates directly with the tracking platform's server, bypassing the user's browser entirely. It is more reliable than pixel-based tracking because it is unaffected by ad blockers, cookie restrictions, and client-side failures.
Postback
A postback is a server-to-server HTTP callback used to confirm that a conversion event -- such as a registration, FTD, or purchase -- has occurred. Postbacks are more reliable than browser-based tracking because they are not affected by ad blockers, cookie restrictions, or client-side failures.
Affiliate Link
An affiliate link is a unique tracked URL assigned to an affiliate that attributes clicks, conversions, and commissions to the correct partner.
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.
Conversion Rate
The percentage of clicks or visitors that complete a desired action, such as making a first deposit, opening an account, or purchasing a trading challenge.
