Sub-ID / Sub Tracking
TL;DR — A sub-ID is a custom label added to an affiliate link, letting a publisher break down their conversion reports by campaign, placement, or channel. Unlike UTM parameters, which feed external analytics tools, sub-IDs are read by the affiliate platform itself and show up directly in commission reporting. Publishers should check their Involve Asia dashboard reporting options to see what level of breakdown is available for their tracking links.
What Is a Sub-ID?
A sub-ID (sometimes called sub tracking) is an extra value added to an affiliate link that the platform stores alongside each click and conversion. It lets a publisher tag their links with their own labels — “blog,” “instagram,” “newsletter-june” — and later see performance broken down by those labels.
This is especially useful for publishers running the same offer across multiple channels or campaigns. Without sub-IDs, all conversions for an offer look the same in reporting. With them, a publisher can see exactly which placement or campaign actually drove results.
The key difference from UTM parameters is where the data lives. UTMs are read by tools like Google Analytics, separate from the affiliate platform. Sub-IDs are read by the affiliate platform itself, so they appear directly in commission and conversion reports tied to earnings.
Sub-IDs and Involve Asia
For publishers managing multiple campaigns or placements for the same offer, sub-ID style tracking is a useful way to compare performance without relying solely on external analytics.
Publishers can check their Involve Asia dashboard reporting to see what tracking breakdown options are available for the links they generate, helping them understand which content or channels are driving the conversions behind their commission.
