Awin vs Post Affiliate Pro: Links, Tracking, and Reliability Compared
Awin is major affiliate network known for the broadest EU/US retail merchant coverage, especially post-ShareASale-merger; Post Affiliate Pro is white-label affiliate software known for small-merchant in-house programs. They solve different problems, and many publishers use both at once for different merchants. Mechanically they differ in link anatomy and failure behavior — compared in detail below.

How Awin links fail
Merchant leaves Awin
The most damaging failure. The link redirects to Awin’s closedMerchant page or shows "this link is inactive". Clicks keep flowing, commissions stop. Awin does not rewrite or fix your old links when a program closes.
Destination page dies
The Awin hop works, the click is tracked, but the ued destination now 404s or redirects to the merchant’s homepage. You keep your cookie but conversions collapse because visitors land on the wrong page.
How Post Affiliate Pro links fail
Banner or campaign deleted
The a_bid no longer exists; depending on configuration the link errors or falls back without attribution.
Merchant retires the software
Pages load normally; a_aid does nothing. Detectable only via test conversions or your affiliate dashboard on the merchant’s program.
How to choose
- ▸Choose Awin for the broadest EU/US retail merchant coverage, especially post-ShareASale-merger.
- ▸Choose Post Affiliate Pro for small-merchant in-house programs.
- ▸They are different kinds of platforms, so this is rarely an either/or: many publishers run both simultaneously for different merchants.
- ▸Whichever you use, the operational risk is identical: merchants leave, campaigns end, and product pages die — on both platforms — without notifying you. Monitoring matters more than network choice.
Frequently asked questions
Can I use Awin and Post Affiliate Pro at the same time?
Yes — publishers routinely run multiple networks side by side, since each merchant picks its own network. The cost isn't platform conflict, it's audit surface: two networks means two sets of link mechanics to monitor.
Which pays higher commissions, Awin or Post Affiliate Pro?
Commission rates are set per merchant program, not by the network — the same brand often pays identical rates wherever it runs. Compare specific programs, not platforms.
Do Awin and Post Affiliate Pro links break differently?
Yes. Awin: merchant leaves awin is the most common failure. Post Affiliate Pro: banner or campaign deleted. Afterlink validates both with network-specific error detection.
