SubID Parameter Guide

Get answers about the subid parameter and its role in affiliate tracking. Understand the key concepts and how they apply to your conversion tracking setup.

In affiliate marketing, a subid parameter is a unique identifier that tracks individual clicks and maintains source attribution. The AnyTrack Tracking Tag automatically tags your affiliate links with subid parameters through AutoTag.

Tracking Individual Clicks

The subid parameter allows you to track each click by appending a unique identifier to your affiliate tracking link. Analyze click attributes like campaign, ad group, ad, and variables.

When running Google Ads campaigns, Google provides a unique GCLID (Google Click Identifier) for each click. Use the subid parameter to pass this identifier to your affiliate network.

Maintaining Privacy

Use AnyTrack to generate your own unique clickid and pass it as the subid parameter. This masks your traffic source from the affiliate network while enabling accurate click and conversion tracking.

Server-Side Tracking (Postback)

The subid/clickid parameter is critical for server-side (postback) tracking, which is more reliable than cookie-based tracking. It is not affected by ad blockers, cookie deletion, or browser restrictions.

The subid/clickid parameter connects your traffic source to affiliate networks. When a conversion occurs, the affiliate network sends a postback with the subid/clickid. Your tracking platform matches the conversion to the original click and attributes it to the correct source.

Using subid/clickid for server-side tracking provides accurate campaign performance data and enables data-driven optimization decisions.
