Meaning of Postback: Affiliate Marketing Program Context

When setting up an affiliate program, one of the key decisions an advertiser/merchant has to make is what tracking method to use.

Most present-day affiliate programs rely on a pixel embedded into the confirmation/”thank you” page. This (somewhat of an industry default method) is meant to close the loop between the initial end user click on an affiliate link and the end user’s reaching the thank-you-for-your-business page. The affiliate commission is then triggered by (and credited upon) the pixel firing at the moment the customer reaches their confirmation page.

Postback tracking, on the other hand, represents a slightly more technically sophisticated of a method of crediting affiliates for the business they refer. Its essence is grounded in server-to-server posting, whereby instead of relying on the pixel firing, the conversion record (and consequential affiliate commission crediting) is triggered by the advertiser’s server passing the necessary data to the affiliate program’s platform’s server.

Server-to-server affiliate postback

Let me give you a real-life example. We have a client who employs two affiliate payment models within the same affiliate program: PPL (pay-per-lead) and PPS (pay-per-sale). The affiliate program is run on an affiliate network which supports both pixel-based tracking, and postback tracking. The advertiser in question is paying affiliates $X per lead when a referred user signs up for a free account, and (on top of the PPL amount) Y% of the sale amount, should the lead convert into a paying customer. For the PPL part this affiliate program relies on pixel firing on the confirmation page, whereas the PPS payout is posted (to the affiliate network’s server) by the advertiser once/if the sale occurs.

While implementation of postback requires a higher level of technical expertise (than the simpler-to-integrate pixel-based tracking), it’s a method that is widely supported by affiliate platforms of all types: including all types of affiliate networks and affiliate software for in-house-based affiliate tracking/programs.
