Key takeaways
  • Affiliate tracking must connect traffic identifiers to network-reported outcomes.
  • Sub-IDs and postbacks are core tools for granular attribution.
  • Reconcile tracker data against the affiliate network as the commission source of truth.

The affiliate tracking loop

An affiliate sends traffic through a link containing or generating an identifier. The offer or affiliate network records the visit. When a conversion occurs, the network can return the identifier and conversion details to the affiliate's tracker through a postback, API, or other integration.

Why sub-IDs matter

Sub-IDs let you encode campaign dimensions such as source, ad, placement, keyword, or creative without creating a separate account for each variation. A stable naming taxonomy makes downstream optimization much easier.

Postbacks and server-to-server data

A postback sends conversion data between systems without requiring the customer's browser to load a pixel. It is widely used in affiliate workflows because the conversion may happen on a merchant site the affiliate does not control.

Reconciliation

Your affiliate network determines the payable commission. Use your tracker to analyze traffic and attribution, but routinely reconcile sales, reversals, payout values, currencies, and duplicate events against network reporting.
